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.

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 749041

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. 691318

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. 541457

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. 521912

Review from a similar EZ Valve in RV Sewer


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

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

1 year review. Purchased the Valterra electric waste dump valves (3 ea.) and after 1 year the motor on one unit has failed. I did reorder a replacement unit as I still prefer these over traditional cable pull valves. 670455

Review from a similar EZ Valve in RV Sewer


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! 683771

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. 763808

Review from a similar EZ Valve in RV Sewer


I had to replace and old valve that had jammed on me. The original valve was installed about 4 years earlier. When they work they are great. when they don't, the sewers back up. I had to manually open up the old valve in order to flush the tank before replacement. 711149

Review from a similar EZ Valve in RV Sewer


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

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

Review from a similar EZ Valve in RV Sewer


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

Review from a similar EZ Valve in RV Sewer


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

Ask the Experts about this Valterra RV Sewer

  • 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...

  • 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....

  • 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.

  • 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...

  • 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.

  • 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.

  • 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!

  • 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...
