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.

Review from a similar EZ Valve in RV Waste Valves


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.

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!

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.

This was the 3rd valve I put on it. This one was working when I traded the RV in on a newer keystone Avalanche. Has manual waste tank pulls which I will keep.

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.

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


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.

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


These valves are a huge improvement over the manual types. I wound up disassembling the unit sent and just replaced the valves, as the assembly was narrower than my existing set. 8 1/4" between the flanges, mine was 11"+, No instructions were included. Took most of the day to complete single handed. Extra hands would be very helpful...

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.

A very useful valve, hope it works better than the last one! The last one of these had the plastic break where it opens the valve. This new one seems to be different, hope it's stronger! Just wish it wasn't the black tank! etrailer was especially helpful with a UPS problem but got a new one out to us right away. Very nice people to deal with!

Review from a similar EZ Valve in RV Waste Valves


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.

Review from a similar EZ Valve in RV Waste Valves


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.

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

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

Review from a similar EZ Valve in RV Waste Valves


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.

it is so nice to not have to go outside in the winter months and have to crawl under my toy hauler to empty my blackwater tank. Got an electrician who installed the switch right in the bathroom for easy access. No problems at all! Now to get one for each tank for individual control!

I bought 3 of these valves and installed them to replace my cable actuated valves. They were delivered in a timely manner and very well packaged. The time to install these was much faster than expected. They came with everything needed. Crystal was very helpful in the buying process. I will definitely buy from etrailer again.

Ask the Experts about this Valterra RV Waste Valves

  • Is there a Specific Place to Get 12 Volt Power to Valterra EZ Valve Electric Waste Valve # E40-8
    Honestly if it were me installing Valterra EZ Valve Electric Waste Valve # E40-8 I would run a new wire to the battery. If you tap into an existing 12 volt circuit the extra load on that circuit could cause a fuse, or breaker if equipped, to blow. Basically you would have to be sure that the combined power draw of the valve and whatever else may be on that circuit is within the capacity of that circuit. This particular valve pulls 2.5 amps.

    Electric valves like the Valterra EZ Valve Electric Waste Valve for RV Black Water Tank - 3" Hub to 3" Spigot # E40-8 are only operated on 12v power. I recommend getting a converter like the Progressive Dynamics Inteli-Power RV Converter and Battery Charger - 12V - 30 Amps # PD9130 along with the Charge Wizard for Progressive Dynamics Inteli-Power PD9100 Series Converters # PD9105 and battery which it will maintain.

  • Can the Wires Between the Valve and Switch On the Valterra EZ Valve Electric Waste Valve Be Extended
    The Valterra EZ Valve Electric Waste Valve part # E40-8 is an excellent option for hassle/mess free dumping. The wire leads on the valve are about 8-1/2" long whereas the wire leads on the switch are about 7' long. If you need more space between the valve and switch then you can certainly extend the wires as needed with some butt connectors. That said, just be sure to cut far enough behind the connector that you still have room to attach the butt connector.

  • What is Shortest Cable Length for RV Sewer Dump Valve
    The shortest cable length for the RV dump valves is 36 inches like the part # 34466N4AB36GM you referenced. You can loop the cable to take up the extra slack and it will work fine. The bigger the loop you can make the better as that will allow the cable to slide the easiest. We do have an electric version of this with the part # E40-8 as well.
