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.

Replace the standard waste valve on your RV's black-water tank with this electric one so that you can open and close the valve with the flip of a switch. Light comes on when valve is open. Wiring harness and 2 switch plates included.


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.


After one year these valves have been flawless. I added one for black and one for grey tank on our Montana 5th wheel. So much better than the stiff cable valves it had from the factory that never completly closed.


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.

You mentioned that the clip is not holding to the valve handle correctly. I wanted to see if you could send a picture?

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.
-- Etrailer Expert Jenny N - 04/26/2022


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.

After a year of usage the valve is working very well. I really like being able to flip the switch to drain the tank.
Dennis T - 06/29/2022


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.


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 .


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.


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.
robert a - 04/09/2020


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.
Mjh - 03/07/2021


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.


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


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.


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!


This project works just as advertised. I am a Mobile RV service man and this is perfect for seniors who have trouble getting down to operate manual valves. I now have two other customers wanting these installed next spring.


Just installed, Easy, No Issues
- quality appears to be good, works fine, would purchase again
Con - Circuit breaker little cheap looking, wire harness too short, needed to
extend for my installation
Would like to see in a 1 1/2" direct replacement for gray water tank.


Just recently learned about etrailer. Now that I have received my order, the excellent order status notification and followup by etrailer I have book marked the company for future reference. Easy to do business with and excellent customer service.

I will be doing business with them again when I have a need for rv products in the future.


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!


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.


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


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!


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.


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.


Great customer service from Super fast shipping. Item looks to be easy to install, I have not installed it yet. Looks to be good quality and should last many years of service.


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.


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.

  • 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 the...

    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.

    The Valterra EZ Valve Electric Waste Valve for RV Black Water Tank - 3" Diameter # E1003VP does not require any lubricating of the rubber seals.

  • Switching From Manual To Powered Mode On The Valterra EZ Valve Electric Waste Valve
    The manual handle on your Valterra EZ Valve Electric Waste Valve for RV Black Water Tank - 3" Diameter # E1003VP needs to be connected to the black powered arm behind it that goes in and out to open the gate.

    Yes you are correct Valterra EZ Valve Electric Waste Valve for RV Black Water Tank part # E1003VP does come with everything you will need.

  • 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.

  • 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 for...

  • 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.
