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.

Video Transcript for Review of Valterra RV Sewer - Electric 3 Hub to Hub Waste Valves - E40B-8

Today we'll be taking a look at the Valterra EZ Valve electric waste valve for RV black water tank. This is going to give you an electric valve to operate your tank remotely, so you can open that and close that FRET with a push of the switch here.It comes outfitted with that black water tank plate, but you can retrofit this for a gray water tank, and it'll have a replacement plate for that. You will need to get an adaptor, though, to size this valve down from 3" to 1.5" to work with a gray water tank.This is going to be a really easy option for opening up that tank, getting your tank drained out, and then closed back up, without having to get under your RV or even get out and pull any cable or pull a handle.It does have a handle up at the top, so if you're dry camping or if there's a power failure, you could pull this little keeper here and then operate the valve manually. Pull it up, push down, and you can take care of business there. That little ring just pops back in place and keeps that handle locked in whenever it's being operated by our motor.It has a built-in 5 Amp breaker, so that's going to provide circuit protection for the unit, so we don't have to worry about changing any fuses. It just resets with the push of a button.

We'll have a light on our switch to indicate when it's open. That'll turn red there, and then whenever we need to reset that breaker, we just press the button down at the bottom to get it working again.Now this is going to be a 3" hub, so that inner diameter will work with 3" spigots, and the hub will be the female end, so then our other pipe will fit inside there, and this is a hub-to-hub, so it's the female end on both sides.Our wiring harness comes pre-installed there to make the connection between the valve and the switch. We just have this plug to connect, and then power and ground to connect as well.It's a pretty easy install, just replace that valve out, plug up your wiring, and you're good to go. You do want to get some ABS solvent bond to properly install this, to make sure that there's no leaks or anything like that. That is sold separately.

You can find that here at etrailer.com, using Part #A05-0303.This is compatible with 12-volt systems. Again, our passage diameter is 3". The wiring length that we get is eight feet. The valve harness is one foot long, and then our switch harness is seven feet long. It has a power draw of 2.5 Amps, and that's going to do it for our look at the Valterra EZ Valve electric waste valve for RV black water tank..

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 Valterra EZ Valve in RV Sewer


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

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. 491543

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! 453745

Review from a similar Valterra EZ Valve in RV Sewer


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

Review from a similar Valterra 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

Review from a similar Valterra EZ Valve in RV Sewer


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. 438916

Review from a similar Valterra 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 Valterra 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

Review from a similar Valterra 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 Valterra 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

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. 577660

Ordered and received in 3 days with free shipping. Installed the following weekend in about 2 hours. Tested prior to and after installation. All necessary materials were supplied in package. The valves stroke cleanly and quickly. Indicators show open valves. Good quality switches. I am extremely happy with these valves. Wish I knew of them sooner. Well worth every penny. 572515

Do you have a question about this 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....

  • 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...

  • 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.
    view full answer...

  • 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.

  • 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...
