So I have convinced myself that it has come the the to accept the inevitable and replace both the black and grey water tanks along with all the associated leaking valves and fittings. Will also replace the tank monitoring system with something more reliable.
Last week I filled, flushed, and drained all the tanks till only clear water was flowing. Used a power wand down the toilet to fill it full. Grey water valve is missing it's handle and looks like the PO simply sealed the rod hole and left it permanently open. Black tank leaks around the outlet from damage when the PO high centered the coach. Various other leaks are coming from the top of the tank.
Called an RV repair and their estimate started somewhere around $2000 to replace the two dirty tanks, valves, connectors, all the associated piping, and install a monitor system (SeeLevel II 709-PH).
A couple of local GMCers have offered their assistance and skill in an offer to assist me in replacing the tanks ourselves. We may have the availability of a pit. I figure the material cost of the tanks, valves, connectors, and piping to be around $1000 (plus some steak dinners).
Is this an area I should leave to the professionals? I've worked with ABS piping before and it isn't rocket science. I also have quite a bit of experience in electronics so the monitoring upgrade doesn't scare me either.
We'll be pretty much duplicating the existing system. One of the guys is trying to talk me into a macerator and electric valves. I think the electric valves are a bit much.
Are there any pitfalls or surprises that I should be aware of BEFORE I start this adventure (yeh, I'll flush out the tanks a couple of times more).
Oh, as it states in my signature line. This is dealing with a 78 Royale (Rear Twin) coach.
Here's a couple of pics of the existing system
