Has anyone ever rebuilt a leaky toilet valve? The new coach has one of those plastic toilets and it has a slight leak that causes the water pump to cycle every so often, just enough to wake you up. I can swap the toilet from my other Barth which is a porcelain newer type.

I put new seals in a Thetford Aqua Magic IV. Not difficult.

Twice during my RV years, the toilets needed fixin'. I hired 'em out. It a dirty smelly job that all RV repair places can do. Keep the economy strong. Hire out those smelly jobs. Also, the second time, an honest repairman said that he could install a brand new toilet for about the cost of removing and replacing valve kit in my 15 yr old unit, because valve kits do not always solve leaks in older units. The total cost for complete replacement was only $40 to $50 higher than repairing the thing; i.e., if you hire it out like I did. Best toilet preventative is to keep a bit of flush water above valve, so valve does not dry out. Repairman also recommended vaseline on top and bottom sides of valve will prolong life and abate some of the tank odors leaking past valve. Also, vaseline tends to repel water and leak thru valve is slower. One repairman said he tries vaseline w/ many units first to see if it will fix leak w/o valve replacement. Most common toilet valve problem repairman stated was toilet paper the gets rammed into the groove by the valve. Paper clip can pick out compacted debris in that groove, but that's a smelly job too. If you turn on the bathroom vent fan while working on the toilet, it pulls all the tank odors past your face, so the repairmen I hired both times did it fanless.
