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.

  • 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 #...

  • How Long are the Wires on the Valterra EZ Valve Double Electric Waste Valves Part # E84-8
    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).

  • 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 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.

  • Grand Design 2600RB Waste Valve Replacement
    You're on the right track here- the Valterra EZ Valve Electric Waste Valve for RV Black Water Tanks # E40-8 is the part you're looking for to put an electric open/close function on your black water tank. Adding in this electric switch for your sewer will allow you to avoid having to crawl under your slide out each time you want to open/close the black water tank- no more pulling the tank handle. You will use the present plumbing and replace your existing cable/handle with the # E40-8;...

  • 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.

  • 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...

  • 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 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 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.
