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.

  • Does the Valterra EZ Valve Electric Waste Valve for RV Black Water Tank Continuously Draw When Open
    Hi Jeff, Great question! The Valterra Easy Valve # E40B-8 is designed to be energy efficient, it only draws power while it’s actively opening or closing. That process usually takes just a few seconds. Once the valve reaches either the fully open or fully closed position, it stops drawing current thanks to built-in limit switches. So, even if the valve is left open, it won’t keep pulling power and draining your battery. That means you won’t run into a situation where the battery dies just...

  • Determining The Correct Replacement Brake Lines For A 2024 DRV Mobile Suites 40KSSB4
    There unfortunately isn't a guide to tell us exactly what your 2024 DRV Mobile Suites 40KSSB4 uses so you'll need to check the length of the hose, fitting sizes, and if there is a 90 degree bend or if the fittings are straight. For example, the Kodiak Hydraulic Brake Hose # bh-3mfs90ff-1-5 is 1.5' in length, has a 1/8" hose inner diameter, and has 3/16" fittings with one 90 degree bend.

  • Troubleshooting a Valterra Electric Waste Valve That Has a Open Valve Light Stuck On
    It could just be a weird connection the wires are making with the switch causing the light to stay on. I'd recommend checking the connections to the switch and make sure they're seated properly and making a good connection to the switch. If the wires going to the switch are fine, and everything is connected properly, then I'd recommend just swapping out the switch with another switch like the Single Momentary Switch # 37213845.

  • 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...

  • 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 #...

  • 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...

  • Does the Valterra EZ Valve Electric Waste Valve Require Routine Maintence?
    The Valterra EZ Valve Electric Waste Valve for RV Black Water Tank item # E40B-8 may benefit from being installed up in your enclosed underbelly with the Valterra ABS Solvent Cement item # A05-0303 to help prevent the sewer pipes from freezing if you camp when the weather is cold. This will also protect the valve from damage caused by road debris while you are driving. Other than that there are no suggested routine maintenance schedules to follow. You will definitely want to keep the motor...

  • 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,...

  • Can Center Section of Electric Waste Valve E40B-8 Replace Manual Setup
    To make your life easier you could just remove the center section of your current waste valve and then install just the center section of the part # E40B-8 so that you can convert to an electric setup without having to deal with a much more involved install since the pipes are plastic welded and can't come apart without cutting.

  • Troubleshooting A Valterra Electric Waste Valve That Keeps Blowing The Fuse
    I spoke with Valterra and they stated that there's a microswitch inside of the Valterra EZ Valve Electric Waste Valve # E40B-8 that isn't sensing that the gate is fully closing causing the fuse to blow. This could be either an obstruction blocking the gate or just something on the sensor itself. I recommend using a hose to try and clean out the line and seeing if that solves the issue. You can hook on an adapter like the Valterra Hydroflush Reverse Flush Adapter # F02-4110 to connect a...

  • 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.

  • Can You Replace Just the Valve When Upgrading To Electric Sewer Waste Control
    In order to upgrade from manual to electric waste control valves you'll need to change out the entire housing/body as well. For this, we have quite a few options which will depend on if you have separate valve like part # E40B-8 or combined like part # E85-8. These options both have hub fittings which are the easiest to change out since all you need to do is cut the old ones off and slide the new ones on with some solvent part # A05-0303.

  • Does Valterra EZ Valve Electric Waste Valve Have Gaskets/Seals Between Valve and Ends
    Yes, there are gaskets/seals between the valve portion of the Valterra EZ Valve Electric Waste Valve # E40B-8 and the 3" hub sections. Just use ABS Solvent # A05-0303 when you install this to 3" spigots and you won't have to worry about any leaks!

  • Upgrading To Electronically Controlled Waste Valves
    If you're wanting to have an electronically controlled valve for just the gray tank then you can use the Valterra EZ Valve Electric Waste Valve for RV Black Water Tank - 3" Hub to 3" Hub # E40B-8 along with a reducer # T1041-1 to make the connection between the valve and gray water pipe. There currently are no electronically controlled valves with a 1-1/2" opening so you'll have to use a black water tank valve to accomplish this. You could also use the Valterra EZ Valve Double Electric...

  • 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....

  • Can The Valterra EZ Valve Electric Waste Valve Replace the Manual Valve Already On My Camper?
    Yes, the Valterra EZ Valve Electric Waste Valve # E40B-8 uses the same size 3" Slip Hub with Flange # T1005 that you have on your sewer line already. The Valve may benefit from being installed up in your enclosed underbelly with the Valterra ABS Solvent Cement # A05-0303 if you do camp when the weather is colder to help prevent the sewer pipes from freezing. It will also protect the valve from damage caused by road debris while you are driving.

  • 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...

  • Will 3" PVC Pipe Fit The 3" Hubs Of The Valterra EZ Valve Electric Waste Valve
    The hubs on the Valterra EZ Valve Electric Waste Valve for RV Black Water Tank # E40B-8 will have an inner diameter of 3". PVC pipe is measured by it's internal dimensions so a 3" PVC pipe would actually have a 3.5" outer diameter and would not be compatible with the # E40B-8. You would want to use ABS pipe, which can be purchased in a 3" outer diameter to fit the hubs.

  • How Do I Lubricate/Maintain My Waste Water Valves
    If you were to ask a waste valve manufacturer like Valterra or Dometic, they would tell you that their valves do not require lubricant. That being said, along with regular cleaning/flushing, adding a lubricant like a silicone plumbers grease will help the valve operate more smoothly over time, and it can help the seals last longer. I am sorry to say that we do not offer any such lubricant here at etrailer, but I imagine it would not be too hard to track down locally.
