Electric Dump Valves

Posted this on a couple of other forums, and am looking for opinions...

Debating adding Drain Master electric dump valves.

Anyone done this?

Who did the work? Difficult DIY??

Why bother with the expense when there are manual gate valves on the black and gray water tanks? Just another electrical device to give you problems in my humble opinion.

My response exactly. What benefit would you gain from the expense and trouble of installing electrically operated valves?

Doesn't look that difficult to put the valves on (make sure the tanks are clean and empty). The more difficult part is running the wires (will need power and then to the panel for the switches).

I can see them being useful if you were at one place for a long time but not very when setting up or getting ready to leave (as you'd have to go inside to flip the switch instead of pulling the valve handle right in front of you).

No electric toilet or dump valves for me. Replaced the Factory black tank valve with a hand pull that I access behind water manifold. Simple design, works every time.

So mount the switch right in front of you, it doesn't have to be inside the coach.

Not really any advantage to having electric valves, I've always considered them a gimmick that's not really needed.

Installed them several years ago. Will do it again when we buy next unit. Had a set on a '00 Sunnybrook prior to this one. I can open or close from inside or outside. No more stiff controls.

Interesting how many who have never had them have such strong opinions about them.

I actually did have them on our DP, was just as easy to pull the handle as it was to flip the switch. I firmly believe in KISS.

If any of the responders, except anijet and Cummins, owned a DRV trailer, you would understand why lots of DRV owners opt for electric or dispensing with the outside pull handle........especially the older ones.

I too subscribe to the KISS methodology, however our valves operation, as with other DRV's, is difficult and I fear I'm going to pull too hard one day & rip off the wall of the trailer.

That said, I wanted to hear the experiences of those who have utilized the electric valves to assist me in the decision. Sounds like those with DRV's that installed it have had good experiences.

How about a picture? Did you reroute the OE cables or buy new valve with a shorter cable?

My black tank valve is OK, its the gray tank valve that's really hard especially if its cold out. I remember your picture of the mod you did. The gray tank valve is under the 5er, isn't it?

I believe you access the grey valve by moving aside the black plastic box that the drain lines come out of. Since the box is put in place with no way to actually remove it with the lines in place, you can only move it aside unless you cut into the box itself to remove it.
Haven't done this myself, but have seen several reports on doing this in the past.
As to the black valve, I just finished replacing the seals due to leakage--and in doing this, it freed up the cable movement to where it is almost too easy to pull. If I ever have to dig into the black valve again, I believe I will go the electric route also.
As to replacing it with a manual valve--I have too many items in the basement that would have to be moved each time I wanted to access the handle--but that's my problem.

Correct. There are I think 6 screws that have it bolted on. You also might need to clear out some of the spray foam that keeps the pipes and pan sealed up. Then just move it aside and you will be able to access the gray valve. At least in my 2016 model.

Never had electric valves on tank dumps. There are probably some good reasons for them on some rv's but at the same time I can see chances of accidental spills being a huge concern. Expecially if the switch in anywhere other than near the discharge hose.
