Valterra electric valve pieces

The switch plate, wiring, seals, and hardware needed to install this electric waste valve on your RV's black water tank are included. The switch plate installs in the RV's control panel. The waste valve secures to existing pipes using ABS solvent cement (A05-0303 - sold separately). A booklet with step-by-step instructions and a template for drilling are also included.


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.

Is outstanding product make certain to order lots of wire however depending on where you want to run your switch. I wanted mine in my cabin next to my refrigerator.




by:

The Valterra valves work great unless they get wet on the outside and then the electronics corrode and stop working. This happened twice in the past to me personally. If they sealed the motor they would be awesome, but I still love the convenience of the remote switch.




by:

This replaced a mechanical one I had for the black water. It was a relatively easy install, the install of the valve was straightforward and the wiring for the switch was easy with the worse being choosing a location and drilling the switch mounting area. Works great and hasn’t had any problems




by:

This is a very nice easy hookup, 2 wire install. This valve is being used on a 1010 gallon tanker trailer for an agricultural application. The valve comes prewired with heavy duty wiring and very sturdy crimped on connectors. The lighted activation switch is mounted into a faceplate with a 5 amp DC circuit breaker. Most attractive about this valve is the very reasonable price. This is a lot of valving for the price.




by:

These valves are fantastic, after a year of use they function flawlessly, and I don’t have to get on my knees anymore to pull those stupid valve handles.




by:

Valve works as promised. Would have been helpful to have instructions and panel mounting screws but I have [on-line videos] and a can of spare hardware. I wonder if the manufacturer knew where I was mounting everything as the power connection plug was JUST the right length.




by:

VERY good service and VERY quick delivery. They have a good system for taking orders, processing them and keeping the customer informed along the way.




by:

Everything they describe, and we tested and is working perfect

Review from a similar EZ Valve in RV Waste Valves


Nice valve for remote operation . The wiring is 4 ft from switch to motor/valve, and 3 ft of wire for power. I replaced power wire with a 10 ft piece which was only $9 bucks. Take pic of switch wiring cause you need to remove wires from switch to pass wires through any holes you drill in floor and cabinets, etc . Watch out for water , electric wires when drilling holes. Hole needs to be at least 1/2”for wire ends to pass through. If wood is thick I would do 5/8” hole . Pass big wire ends through first and smaller next. Or cut wire ends off and recrimip new ends after running wires.

Review from a similar EZ Valve in RV Waste Valves


So far a very good valve. I just removed the old cable valve and this slipped right into it's place.
There was one little surprise, the instructions did not indicate which 12v wire was positive. There is a black and white wire. I assumed black was positive, it's not. So of course the valve opened when I connected the wires.


Comments
After a year of usage the valve is working very well. I really like being able to flip the switch to drain the tank.

Review from a similar EZ Valve in RV Waste Valves


I bought this item hoping it would fix the issues I had with the factory installed cable, NOPE. This part is no better than the cable system. The clip that hold the valve handle to the electric motor doesn’t clip on correctly, I even tried making it work with zip ties, it worked for maybe two weeks, now I just crawl under the RV and operate it manually. Don’t waste your money.


Comments
You mentioned that the clip is not holding to the valve handle correctly. I wanted to see if you could send a picture?
-- Etrailer Expert Jenny N - 04/26/2022
Hi thanks for reaching out, unfortunately the valve is in a very hard spot to get a decent photo. I am out of town the rest of the week, I could try to take a photo this weekend if needed.
-- comment by: Ryan - 04/26/2022
I reached out to the manufacturer who advised that often the handle is not in the correct position and if it is not it will cause problems wit the use of the valve.

Review from a similar EZ Valve in RV Waste Valves


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.

Only reason it's not five stars is the shipping, they wouldn't let me ship it to a PO box because of the wait but UPS took it to the post office??, Otherwise love etrailer they are alot of help and these valves which I didn't need the Y but it was cheaper than buying 2 single valves.

Review from a similar EZ Valve in RV Waste Valves


The Drain Master cam-lock waste water hose is second to none, but after having to use a small allen wrench to manually open/close a failed Drain Master black tank valve, I replaced both with this Valterra assembly. They require a fair amount of space above them to open, but it is much easier to manually operate them, if necessary. They are well-constructed. No leaks, no problems after a year of use, and etrailer offered quick delivery and excellent customer service.

Keep in mind-- the switches are a rocker design that makes open/close positions less obvious, and in bright sun, the red led may be hard to see. I learned this while flushing out my black tank. After I was finished, I reinserted the stopper, thinking the black tank valve was closed. The next time I went to drain the tanks, I took the stopper out, and had a 40 gallon gusher of raw sewage! One thing I can say about all my RV mistakes- I never repeat them!


Comments
A year later, we are still full-time in the RV. I am using the Valterra valves every couple days and they continue to operate faultlessly.

Review from a similar EZ Valve in RV Waste Valves


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.


Comments
Still working flawlessly.Been recommending this item to all who inquire about it on my rv.

Review from a similar EZ Valve in RV Waste Valves


I would recommend this product to anyone who has long remote pull drains.
It made both the black and gray water work without a hitch. Just smooth full open to full closed. Well worth the money. Install them myself with the help of my son. They bolted right up no problem.

Still working great. Should of made this change long ago.

Review from a similar EZ Valve in RV Waste Valves


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

  • Electric Waste Valve for 4 Inch Diameter Black Water Tubing
    Are you referring to a waste valve for your black water tank? If this is the case than are you sure you have a 4" diameter tube because the industry standard size for a black water tube is 3" diameter which is what most of our waste valves are designed to work with. We do not have any 4" diameter electric waste valves but you can reduce the 4" diameter black water tube down to a 3" diameter black water tube and use one of the following: Valterra EZ Valve Electric Waste Valve part # E40A-8...

  • Electric Waste Valve Compatibility to Replace Cable Actuated Valves
    The Valterra EZ Valve Electric Waste Valve for RV Black Water Tank - 3" Hub to 3" Hub # E40B-8 can be installed horizontally as well as vertically without any issue. I reached out to my contact at Valterra to confirm and they absolutely can replace existing Valterra cable actuated valves. You will simply unbolt the hubs and make sure the seals are in place when you bolt the valve into your current setup. They did mention that the motor is slightly wider than the valve body, so you will...

  • Why is Valterra EZ Valve Electric Waste Valve Tripping Breaker
    Something getting hung up would not trip a circuit breaker on the Valterra EZ Valve Electric Waste Valve for RV Black Water Tank # E40B-8. If you are having an issue with the breaker getting tripped the issue is almost certainly going to be because the circuit you are wired to is pulling more amps it is capable of. This valve pulls 2.5 amps so you may want to try and wire it directly to a battery if possible.

  • Can Center Section of Electric Waste Valve E40B-8 Replace Manual Setup
    To make your life easier you could just remove the center section of your current waste valve and then install just the center section of the part # E40B-8 so that you can convert to an electric setup without having to deal with a much more involved install since the pipes are plastic welded and can't come apart without cutting.

  • Which Valterra EZ Valve Electric Waste Valve To Use
    You linked to the Valterra EZ Valve Electric Waste Valve for RV Black Water Tank, # E40-8 a 3" Hub to 3" Spigot. 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. Please note the three options of a 3" Hub to 3" Hub - # E40B-8, 3" Hub to 3" Spigot - # E40-8 or 3" Spigot to 3" Spigot - # E40A-8. I suggest you remove the current component and examine what you have. For installation,...

  • Recommended Electric Dump Valves for 2014 Sanibel 3600 5th Wheel Trailer
    For the electric valves, we only have the 3 inch options. We have the hub to hub # E40B-8, the hub to spigot # E40-8, or the spigot to spigot # E40A-8. If you were to convert your 1-1/2 inch to a 3 inch, we do have the double 3 inch electric valves with 3 inch hubs # E85-8 or 3 inch hubs to lug fitting # E84-8. For your slide-out seal, I assume you are referring to weather strip tape like # WS1412 which can be combined with silicone sealants like # 0160297 for extra water protection....

  • How to Choose the Correct Valterra EZ Valve Electric Waste Valve for RV Black Water Tank

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 You Replace Just the Valve When Upgrading To Electric Sewer Waste Control
    In order to upgrade from manual to electric waste control valves you'll need to change out the entire housing/body as well. For this, we have quite a few options which will depend on if you have separate valve like part # E40B-8 or combined like part # E85-8. These options both have hub fittings which are the easiest to change out since all you need to do is cut the old ones off and slide the new ones on with some solvent part # A05-0303.

  • What Wire Gauge Does Valterra EZ Valve Electric Waste Valve Use?
    I spoke with a representative of Valterra who told me that the Valterra EZ Valve Electric Waste Valve # E40B-8 uses 3 wires, each of which are 18 gauge. Please keep in mind that you will need ABS solvent bond # A05-0303 for installation of this valve.

  • Does Valterra EZ Valve Electric Waste Valve Have Gaskets/Seals Between Valve and Ends
    Yes, there are gaskets/seals between the valve portion of the Valterra EZ Valve Electric Waste Valve # E40B-8 and the 3" hub sections. Just use ABS Solvent # A05-0303 when you install this to 3" spigots and you won't have to worry about any leaks!

  • Upgrading To Electronically Controlled Waste Valves
    If you're wanting to have an electronically controlled valve for just the gray tank then you can use the Valterra EZ Valve Electric Waste Valve for RV Black Water Tank - 3" Hub to 3" Hub # E40B-8 along with a reducer # T1041-1 to make the connection between the valve and gray water pipe. There currently are no electronically controlled valves with a 1-1/2" opening so you'll have to use a black water tank valve to accomplish this. You could also use the Valterra EZ Valve Double Electric...

  • Can The Valterra EZ Valve Electric Waste Valve Replace the Manual Valve Already On My Camper?
    Yes, the Valterra EZ Valve Electric Waste Valve # E40B-8 uses the same size 3" Slip Hub with Flange # T1005 that you have on your sewer line already. The Valve may benefit from being installed up in your enclosed underbelly with the Valterra ABS Solvent Cement # A05-0303 if you do camp when the weather is colder to help prevent the sewer pipes from freezing. It will also protect the valve from damage caused by road debris while you are driving.
