Electric dump valves

Hello all, my '14 3150rl has 3 cable operated dump valves.

I had a mobile tech look at the valves and he indicated that both the front grey and black tank valves are 3".

Anyone changed the cable operated valves to electric? And were your black and grey both 3"?

He indicated the add on electric motor kit would not work and I would need to replace the valve assy with a electric valve assy.

Thanks Jim

Was parked next to a rig with those. For some reason either mechanical or electrical they failed and left him with no easy way to dump. So I passed on them. Plenty of motohomes have them, however. Just research the brand you want to go with for problems.

Both those are 3". I threw away the cable pulls for the most dependable valve I could find, a direct pull valve.

Would I be correct that all I need is the valve that would replace the existing valve by removing the 4 bolts on the existing valve and installing the new valve?

Etrailer Valterra 3" Electric valve. # E1003vp.

I have changed valves before they were the manual kind where you just removed the 4 bolts, changed the rubber seals and installed the new valve.

Going to have the mobile service guy look at the elec valve video to confirm room to install a pair of these.

Thanks Jim

Its same as manual valve 4 bolts. But you need to run wiring from valve back to switch added in convenience center and to battery. I put switch in hole from the old pull handles. Will have a switch for each valve.

Thanks, Jim. Going to mount the switches on the plastic panel that hides the back side of of the convenience area. My cables are at the bottom of the panel and the switches would get wet from disconnecting the black tank flush hose.

Have 12vdc close from the compartment lights.

Again Thanks Jim

Just me, but I would be afraid I would do something stupid like fit the switch before I put on the hose (by accident or due to SoneTimers), and then get something caught in the valve so it wouldn't close. This is how my life is, if something stupid can happen it will. Like the bracket on our last motor home breaking and grinding off the black water valve. The worst part was cleaning all the TP off the towed vehicle.

JMHO, but I'd never go with electric dump valves. Something else to break, then you have a real mess, and, how hard is it to walk around an manually open the valves...not worth the trouble.

Do the standard cable operated valves have a history of problems? This is our first camper to have them. Is there any maintenance I should be performing?

We replaced our cabled valves with 3 in. Valterra electric valves from e trailer. Wouldnt be without them now. They have a direct pull valves as backup. Also have a manual valve at the dump connection as backup if switch gets opened inadvertantly.

Used a 3 in. x 3 in. hose coupler from hardware store to install, as plumbed piping was too stiff to swap in the valve replacement. Put switches in same spot as old cable pulls.

My SOB TT had the pulls for the valves positioned so that you had to get on your hands and knees to pull them. After my first soggy dump station, electric valves were added. I had no issues with them and if you have a need for them, then go for it.

Now that sounds better, I will look at that.

I've known them to break. They are a nice selling feature but in reality they can leave you in a terrible situation when they break. It is a personal decision to keep them or not. I just chose to avoid the inevitable trouble since I'm keeping the trailer a long time.

They will tend to leak over time. If your rig sits for long periods recommend you exercise them occasionally. Recommend adding another twist on Valtera valve where you connect your hose. It will save you if one leaks and makes the job of hooking up your hose easier and cleaner.

I posted this before but it seems to have disappeared. I had to use 2 hands to pull my black tank valve. I was afraid the cable would break and leave me in a mess in the middle of no where, so I had a new valterra manual valve installed. I can now open/close it with 2 fingers - one if I really work at it. MUCH MUCH better than the old valve and cheaper than the electric ones.

Hi

9 years now with the factory installed pull valve and cables. The only valve problem we have had is with the direct pull kitchen gray tank valve.
