Replacing Drain Valves

We have a Cedar Creek 36CKTS it has always had issues in both opening and closing all 3 tank valves and I'm convinced it will only be a matter of time before one or all fail.

I have decided to replace all 3 valves later on this summer. I think I'll go electric but haven't made a final decision yet.

I'd like to hear from some folks who have gone down this road if possible? Did you go electric and how was the install? Is manual better?

How big of a can of worms is this?

I replaced both of my Valterra valves when I replaced the Y pipe between then because one of the ears had broken off and the connection leaked. Very easy! Dump and rinse both tanks very well. Some leave them open after the mondo rinse and let them drip during drive home -- technique only. Then tip the mh so the driver side is high so the dripping will stop, place a bucket under the y pipe and open both valves if not already open and dry. Then get a cooler of beer and follow the guidance on the Valterra site on how to replace the valves -- way easy. Electric valves??? Why? Are manual valves so hard to pull?

I rebuilt my Tetford (?) valves on my TS with their kit. The extra thing I did was to use pure silicone grease you get from a plumbing supply store and apply it to the slide piece and fill the rubber seals. A shot of silicon spray on the stainless shaft and now you can open them with one finger.

I did read that someone replaced theirs with electric, and then threw them away because of problems & went back to manual.
I personally don't know.

I installed these on my motor home because the valves for my tanks require crawling on the ground under the slide. Yours are exposed to the elements and electric valves may not survive.
