These Thomas pumps for the microphor toilet

[Leroy Eckert]

The first thing to know is how often it cycles. I can barely hear mine. It should not cycle constantly. If it is find the air leak and stop it. My pump cycles every 6-7 hours without use which means I have a small air leak somewhere most likely in the toilet itself.. The Thomas pump can be rebuilt for about $70 in parts. Parts include an O ring head seal, two little metal flapper valves, a piston sleeve and the pump piston itself. When you look at the inside you wonder how the thing could work at all but the piston material(don't know what it is)is tough as nails and runs dry. Rebuild time is about 30 minutes.

The last two we got directly from Thomas instead of BB. Now #4 sounds like it's going. I drain it about once every two weeks. What causes them to give out? Ron & Ruth in 2000 LXI in Port Aransas
