Valterra electric valve gray water switch

You can also adapt the valve to work with your gray-water tank. A gray switch plate is included for that purpose. For this installation, you will need to use adapters (sold separately) to convert the valve opening from 3" to 1-1/2" in diameter.

Valterra electric valve manual use

If you're dry camping or in the case of a power failure, the manual override is easy to use. Simply remove the pin from the valve's lift arm and turn the handle 90 degrees clockwise. Then pull the handle to open the valve.

Video Transcript for Valterra RV Sewer - Waste Valves - E1003VP Review

Today we're going to be taking a look at the Valterra EZ Valve Electric Waste Valve System. This system is going to allow you to open and close your waste valve with a push of a switch. This is a 3 inch waste valve system. It's going to feature a durable high torque water resistant electric motor. It's all built into the unit. Really nice compact design, and the unit's going to feature a 5 amp breaker located here on the switch.

That's going to protect the entire system, and it's very easy to reset if needed. Here on the switch, the unit does feature a switch light built onto the housing right here. That's going to activate immediately upon the valve opening, and then the light will stay illuminated until the valve is completely closed. That gives you a nice visual indicator that everything is closed, as it needs to be. This does require 12 volt DC power. It's going to have an amp rating of 2.5 amps. This has been tested, when it comes to the valve cycle testing, that's going to be at 6,000 cycles. It does feature a manual override.

To activate manual override, we just need to pull this pin out right here, rotate the handle, and then you can open and close the valve very easily, if you ever need to do it manually. You rotate it back into the bracket, put the pin back in, and then now it should be ready once it's hooked up to power, to be used with electric. When it comes to installing your control switch, this switch is going to mount in the control compartment, and requires two holes for the wiring to pass through. You can see back here, it's all plugged in, so you're going to need a hole for this unit, and a hole for this unit. In the instructions, I think on the last page, is actually a drilling template that's to actual size, that you can use to make the installation easier, and to get everything drilled out that needs to be. One hole is going to need to measure 1 3/4 of an inch in diameter. The other one's going to need to measure one inch in diameter.

Here on the plate, it's going to have three mount holes. It does come with the appropriate hardware to get it installed, and those are pre-drilled, so you can easily get the unit installed. When it comes to the valve installation, you'll need to choose a location for the valve assembly that provides plenty of clearance for the valve to open completely. When it's extended all the way up, this is going to have an extended length measurement of 15 and 1/4 of an inch from the bottom of the unit to the top of the handle, when it's fully extended. When it's fully closed, like right now, it's going to measure 11 1/2 inches. That's going to give you an idea whether or not you have the space needed to get this installed. You'll install the valve assembly by gluing the pipes from the waste tank into the appropriate fittings.

It does come with the appropriate seals for leak proof performance, and it's going to come with the appropriate hardware to get the unit installed. When it comes to the wiring harnesses, you're going to have the connection point, right here. These are going to be your male or female harnesses. They connect together, and then they have locking tabs for a secure connection. That harness, the long one, is going to measure around 7 feet in length. Then you're going to have your power wire and your ground wire. All the wiring is protected with a nice, thick casing. Your ground wire is white. Your power wire is black. These are going to measure around 3 1/2 feet long. They come from the back of the switch. The black wire goes to the positive side of the 12 volt DC power source. Ground wire goes to the negative side of the power source. What I want to do now, is simply just hook it up to power. That way you can see kind of the response time that the unit has, and how quickly it opens and closes. Very nice response time. As you can see, that light is on. When it fully closes, it will shut off. Really nice design of the unit. Gearing in the unit is all lubricated, so it's going to offer nice seamless operation. It's just very easy to use. That's going to do it for today's look at the Valterra EZ Valve Electric Waste Valve System. Again, this is a 3 inch, electric waste valve system.

Sorry to say the hardest part of this job was gaining access to the underbelly of my 2012 Volatage 5ther. The installation of the valve itself is pretty simple and straight forward. Works great!! Will probably order the Gray Valve later, but that’s for another day. 491543

Shipped on-time as told through the confirmation email. Arrived perfect and intact-undamaged. All Parts were included. I had it installed with-in One hour of it arriving. Tested for leaks, none and were good to go! So excited about having a remote switch to cycle our black tank now. I know it might now seem like a big deal, but it is when you live full-time in an RV. I have ordered from etrailer before and knew they were my go to source for Parts Online. Always great service people to talk to on the phone. Great Job Guys and Gals! 453745

Nice valve, well built. Everything needed for the install is included. Valve opens and closes quickly. This valve replaced a leaking cable valve that was in a tight position requiring an excessive angle on the cable. Problem solved with this electric valve. I installed a 5" access port in the belly pan in case of failure. Will allow me to empty my tank without having to drop the belly pan. My only complaint is that the switch plate will not fit a single or double gang electrical box. Had to make my own since there was no room to mount the switch plate on my panel. 491907

Except for having to make some minor modifications to my flanges (they were bowed out between the bolt holes) so the actuators were clearing the flange, the install was easy. The flange issue is not the valve manufacturers fault, just how the flange was made. My old valves were cable style and cheap and these will be a great upgrade on Leaky crappy valves. I was tired of getting the sewer surprise every time I dumped. etrailer delivered on time and at a good value. 412130

Replaced black valve that had a kinked cable. A great product. Is working well. Installation was difficult in my case due to the original installation. I used two 3" rubber sleeves (Fernco) to join drain line that had to be parted in two places to free up space for the valve. Feel most owners would not have go to these lengths. Electrics were easy. Still glad I did this addition to my RV. 438916

Every things was in the package , arrive at the time its was schedule . The installation went very good and easy , to dot it your self if you are manuel its will work find. I change a existing cable valve with this electric waste valve , the only bad situation was to work under the RV . The valve work great . 470866

Seems to be a quality product installed easily, haven't had a chance to use them other than installing the valves 718860

- E1003VP

I am more than satisfied with this product. We purchased a brand New Renegade Vienna MH, on a Mercedes Chassis. It is a very nice Motor Home, but the very tight spaces underneath the rear caused the (cable pull) Valves very hard to pull and would not close all the way. To our disappointment the manufacturer could not make them work to my satisfaction. A independent repair facility near us suggested the Valterra Electric valves. The manual valves that were on the MH already were Valterra, so the switch was extremely easy. BEST DECISION I've made in years. I 100% suggest this product 695720

- E1003VP

Can't say enough about these valves. The were fantastically! I'd easily give 5 stars but the one small complaint I have it that I had to cut a clearance bump/blister into my RV corregated basement floor because I couldn't get them in a position where something didn't stick out. That was more an installation issue. Now that they're in we love em! 686641

- E1003VP

This product was delivered a day early with free shipping. Had it installed 08/09 will be happy to see how it works, 683055

- E1003VP

Instalation of the valve was easy on my 1999 Alpen lite St. Andrews. Removeable of the underbelly is simple Alpen lite provides two panels to be removed for easy access to manuel valves. The electrical assembly was straight forward having to add 10 inches of wire to reach my battery compartment. For us folks who are replacing our manual valves with electric it would be nice to have a water proof gang box to fit switch assembly. There are no gang boxes available that fit the switch panel without extensive modification to the gang box. Completed installation in 5 hours. The second valve will take about 2. lol Thanks etrailer for great parts at a great price. 669203

I bought these and installed them On my mother's RV she's 93 years young and summers in northern New Mexico these EZ valves has made her life so much easier wish I would have done it earlier 651363

Great product has been maintenance and trouble free. Easy to install good instructions and so much better to operate if you have the old type pull cable you know what I mean. I'm going to order 2 more one for the two gray tanks and will make a video of those install . I highly recomend this product . And sorry I didn't do pictures are video. 647506

Delivery was fast ,hook up was simple and works great. 647384

- E1003VP

This is such a great product,I don't know why it is not an option more often on a rv.I installed the control switch inside my rv near a window that looks out on the sewer connection.I have the clear 3" elbows on both hose ends of my sewer hose,and can observe from inside, the operation of emptying my black tank.Being able to do so during rainy or cold weather is such a great luxury.I have had this in operation for about a year now and it has performed flawlessly.I chose this brand over others due to the ability to manually operate valve in event of a power loss.Installation was very simple and instructions were very detailed.Will never have a rv without one now. 619404

Very happy with the valve. Should have been put on from the start. 579944

- E1003VP

After a year of use the valves work just like new. Installation was simple and there is enough wire to put the switches wherever you want. The switches could be marked a little clearer for open or closed even though there is a led light. 577660

- E1003VP

Installation was a breeze and it works better that I expected 566387

  • How to Choose the Correct Valterra EZ Valve Electric Waste Valve for RV Black Water Tank
    The difference between a hub connection and a spigot connection is that the hub is the female end and has a lip on the inside that stops the spigot (or male) end where it needs to be. I have attached some pictures to assist. With this knowledge it is just a matter of taking your valve off and choosing the correct replacement: 3" Hub to 3" Hub - # E40B-8 3" Hub to 3" Spigot - # E40-8 3" Spigot to 3" Spigot - # E40A-8 I would avoid going with the option that only has the 3" Diameter...

  • Can a Valterra Electric Waste Valve Replace a LaSalle Bristol Valve
    I spoke with my contact at Valterra, who confirmed that the Valterra valve should replace a standard LaSalle Bristol unit. You can simply slide out the LaSalle Bristol valve, slide in the Valterra unit, and bolt it back in place. The Valterra EZ Valve # E1003VP has the motor mounted directly onto the valve, so as long as you have the space for this, there should be no issue using it with the LaSalle Bristol valves. The ABS solvent bond for installation, # A05-0303, is sold separately.

  • Can the Valterra EZ Valve Electric Waste Valve # E1003VP be Installed Right Behind the Waste Cap
    You definitely can use the Valterra EZ Valve Electric Waste Valve # E1003VP just before the cap to your black water tank to avoid any unpleasant presents when you take the cap off. To install it you will just need to cut the pipe and then glue the appropriate pieces together with Valterra ABS Solvent Cement # A05-0303. A great option to accomplish this is to use the Valterra RV Sewer Slip Hub with Flange # T1005 that has a 3" diameter. Just keep in mind that when the valve is open...

  • 1-1/2 inch Valterra Bladex Waste Valve Recommendation for 1-1/2 inch Gray Water Tank Valve
    Since you have a 1-1/2 inch gray water tank valve what you'd want is the part # T1001VP for that size. We don't have an electric version of this though.

  • How To Secure An Electric Waste Valve for RV Black Water Tanks
    Yes, you are correct in that the piping that runs both into and out of the Valterra EZ Valve Electric Waste Valve for RV Black Water Tank part # E1003VP will be sufficient for mounting and securing the water valve. You will not need to mount any additional brackets to secure the valve. The waste gate has a wiring harness totaling 7' in length. For a proper installation, I recommend using the Valterra ABS Solvent Cement part # A05-0303. I have also attached a review video of this waste...

  • Replacement Waste Valves for a 2014 Heartland Elkridge
    Yes, we have both economy and premium replacement valves for your 2014 Heartland Elkridge. However, in order to recommend options for you I would need to know what type of valves you have as well as their size. The most common is 3" for black water tanks and 1-1/2" for grey water tanks. In most cases there will be a wye in which the black and grey water outlet is combined but they can also be separate so I will need to know which you have. If you just need a replacement economy valve...

  • Does Valterra EZ Valve Electric Waste Valve # E1003VP Install by Just Replacing Old Valve
    You'd want to remove your old valve and use ABS solvent bond like part # A05-0303 to install the part # E1003VP but it basically just installs in place of the old one.

  • Are Other Parts Needed When Installing
    You'll also want some ABS solvent like part # A05-0303 to seal the Valterra EZ valve # E1003VP to to your RV. That's all you'd really need. We promise to have the lowest advertised price if that counts as a special!

  • EZ Valve Electric Waste Valve Installation Positioning and Function
    The Valterra EZ Valve Electric Waste Valve for RV Black Water Tank - 3" Diameter # E1003VP will have no problem with function anywhere between vertical and horizontal. You will only be restricted by the valve mounting flanges on your current system, but you have the option of replacing those to meet your needs. I've attached a video of this system to assist.

  • Does Valterra 3 inch Waste Valve Fit 3 inch Bristol Hub
    The Valterra EZ Valve Electric Waste Valve System # E1003VP that you referenced is designed to fit standard RV waste setups that use 3 inch pipes like what a 3 inch Bristol hub is so yes, it would work.

  • Can a Second Switch be Wired in and Used with Valterra EZ Valve Electric Waste Valve # E1003VP
    Valterra EZ Valve Electric Waste Valve # E1003VP is operated with a switch and the valve would either open or close accordingly. If you are talking about just installing a second switch then it is possible though the switch is not available separately. You might be able to wire in two electric valves but both would either open or close together. But the switches may not be rated for the load of 2 electric valves. This one is fused at 5 amps so you would likely need a separate switch...

  • Waste Valves to Replace Those With Rods That Are Falling Off
    If your waste valve handles and rods are falling off you are going to need to replace your waste valves. I have added a link to our entire selection of waste valves so you can find the exact replacement you need, based on the connection you need. I also recommend considering an electric valve such as the Valterra EZ Valve Electric Waste Valve for RV Black Water Tank - 3" Diameter # E1003VP to mitigate this type of issue.

  • Do Waste Valve Rubber Seals Need Lubricant?
    The Valterra EZ Valve Electric Waste Valve for RV Black Water Tank - 3" Diameter # E1003VP does not require any lubricating of the rubber seals. I do know that some people choose to add silicone plumbers grease to the seals because they believe it helps the seals to last longer, but it is not required and also is not included in the kit.

  • Manual Override on Valterra EZ Valve Electric Waste Valve
    I reached out to the manufacturer about this question and they replied, when the EZ Electric Valve is activated, it is fully open or fully closed. There is no way to throttle the flow. However, this unit, the Valterra EZ Valve Electric Waste Valve for RV Black Water Tank Item # E1003VP, does have a manual override in case you need to have this unit be partially opened or closed, it can be done. To activate manual override, there is a pin that is able to be pulled out, then rotate...

  • Is Switch of Valterra EZ Valve Electric Waste Valve # E1003VP Weatherproof
    The switches of the Valterra EZ Valve Electric Waste Valve # E1003VP that you referenced are considered weather proof but I would still recommend you install them away from direct rain and weather. You'll have to use your best judgment but under a ledge or in a recessed area that won't get direct rain is the best option for long time reliability.

  • Valterra EZ Valve Electric Waste Valve Installation
    Yes you are correct Valterra EZ Valve Electric Waste Valve for RV Black Water Tank part # E1003VP does come with everything you will need. The confusion came from the spigot or hub ends and which one they needed for their application in that question. With a valve that is currently in good shape you will retain your current spigot or hub setup and this valve will simply bolt in between replacing your current valve. This is a great solution because it won't require you to cut and repair...

  • Troubleshooting Cable Waste Valves Not Functioning In Sub-Zero Temperatures
    I'm sorry to hear about the issues you are having in the cold weather. I reached out to my contact at Valterra and they said that cold shouldn't be an issue with operation unless there is moisture in the cables or if the cables have kinks or coils. The orientation of horizontal versus vertical should not be a factor. If it were me, I'd start with trying to lubricate the cable system using penetrating oil like # L11363 and working it as far into the cables as you can by working them...

  • RV Automatic Black Water Release Valve
    We do not offer a lock made specifically for use on an RV waste valve and we are not aware of any item intended for this specific purpose. The nearest thing we do offer is the Valterra EZ Valve Electric Waste Valve # E1003VP which operates your dump valve via 12V power. This is not a lock and the valve can still be manually opened but its primary purpose is to allow remote operation of the dump valve.
