Drainmaster Gate Valves - Best MOD Ever!

Thanks, I agree with you, it is the best Mod ever. I have the 2nd drainmaster controller in the 1/2 bath but now I would like Alexa to control it ?

Neal, did you have to slide the 3” pipe into the black tank to get enough clearance to replace the valves. How easy is it to move?

I don't recall anything needed for the black side, that was the simple swap. The grey side, on my coach used a step down from 3 inch port in grey tank to 1.5 inch pipe (stupid) which I don't think they do anymore. So I replaced that entire pipe on mine to do this mod.

How did you spread the pipes apart enough to get the valves out?

 

[Neal]

The tank itself will slide left/right and hence the piping.

Interesting. Mine are leaking on long trips. Not sitting still and I was concerned about getting the pipes to spread. On the old coach one has to use the biggest pair of channel locks I have ever seen to push the pipe into the black water tank and the slide it out again to reconnect.

Thanks. Hope mine is as easy as yours.
