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.

Fits properly, performs excellent. It would awesome if they would make a way to have 2 switches, one inside and one outside.

Working great

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.



by:

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!



by:

Best purchase ever! One year and not a single failure unlike “other brand” which was replace yearly and hope it worked!

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?

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.

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.

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.

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 .

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.

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!


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.

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.

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

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.

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.

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...
