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.

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.

I installed 3 of these valves on my RV, i've had them for a year now with no problems with the valves themselves the only issue was one of the switch red lights that lets you know it's open went out but really don't need it, I am very pleased

Review from a similar EZ Valve in RV Waste Valves


Good quality components. One of the valve actuators arrived damage. Contacted etrailer and they shipped out a replacement. All in all great addition to my sister-in-law's rig as she has trouble bending down

Review from a similar EZ Valve in RV Waste Valves


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.

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


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


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.

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.

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.

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.

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


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.

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.

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.

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


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.

  • 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...

  • Can Valterra EZ Valve Electric Waste Valve Be Installed Sideways Under 5th Wheel Trailer
    Yes, the Valterra EZ Valve Electric Waste Valve for RV Black Water Tank # E40B-8 can be oriented sideways so it's able to open up under your trailer. The 3" to 3" hubs mentioned in the description are included with the valve. These are the pipe ends on either side and the hub terminology means that they are the "outer" connection - so your existing pipe will need to fit inside of this at both ends. Since it looks like you have one hub and one spigot (the inner connection) on your setup...

    I went out to our warehouse to measure the Valterra EZ Valve Double Electric Waste Valves part # E84-8 for you. The wire lead on the actual valve is about 8-1/2" long whereas the wire lead on the switch is about 7' long for each valve/switch. If you just need the electric valves then we do offer them separately, the Valterra EZ Valve Electric Waste Valve part # E40-8 (3" Hub to 3" Spigot) or the Valterra EZ Valve Electric Waste Valve part # E40A-8 (3" Spigot to 3" Spigot).

  • Can The Switch For The Motorized EZ Tank Valve Be Mounted Outside The RV
    I talked to the install gurus down at the shop. The Valterra EZ Valve Electric Waste Valve for RV Black Water Tank - 3" Hub to 3" Spigot # E40-8 should not be mounted outside in the weather. If you have a storage compartment close to the valve you would need to put the switch inside the compartment to prevent damage to the switch and electrical system.

  • 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....

  • 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. But as far as any 12 volt circuits that are near...

  • 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.

    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 # PD92201 and battery which it will maintain.

  • 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.
