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.

  • 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,...

  • 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 #...

    Absolutely! To install the Valterra EZ Valve Electric Waste Valve # E40A-8 on your gray water tank with 1-1/2" pipe you can simply use the Valterra Eccentric Tank Reducer 3" Spigot to 1-1/2" Hub # T1041-1 on each side of the waste valve to convert the 3" openings to 1-1/2". The Valterra EZ Valve # E40A-8 includes a gray water switch plate for you to use as well. You will also need Valterra ABS Solvent Cement # A05-0303 for a strong leak free connection.

  • 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...

  • 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).

  • Recommended Double Electric Waste Valves
    We have a solution for your double black water waste tanks but not the grey. I recommend the 3" Lug Fitting Valterra EZ Valve Double Electric Waste Valves with a rotating hubs, # E84-8. You can replace the OEM waste valves on your 2020 KZ Durango Gold 40ft 5th wheel with these electric ones so that you can open and close the valve with the flip of a switch.

  • 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....

  • Using Valterra EZ Valve Electric Waste Valve for RV Black Water Tank To Replace Manual Valve
    The Valterra EZ Valve Electric Waste Valve for RV Black Water Tank part # E40A-8 is designed to replace a single 3" black water tank valve. It has spigot couplings on the ends which are designed to slide into a 3" diameter black abs sewer pipe and then attach with solvent like part # A05-0303. If you're replacing an existing valve you would just simply cut the old valve and fittings off and attach the new ones using the method above. Finally, you would run your wires to a power source and...
