My Mansfield Vacuflush will not hold vacuum. If I put about two inches of
water in the bowl it goes dry in less then an hour and then the pump cycles.
I have tried cleaning the inside surface against which the ball seals with
soap and water but it has not helped. Do you have nay suggestions. TIA.

A new "ball, shaft and cartridge kit" should solve the problem.

Btw...your toilet is at least 20 years old...the Mansfield brand name
was changed to SeaLand in 1984 when SeaLand Technology bought out the
marine toilet division of Mansfield Plumbing. So no part #s you have are
still current, but most parts haven't changed.

Call SeaLand on Tues...800-321-9886. And as long as you're doing some
maintenance, I'd replace the duckbill valves (4 of 'em) in the vacuum
pump too. And get a current owners manual for it. Not only will that
give you current part #s and exploded drawings, but just about every
possible symptom, probable causes and cures that a VacuFlush can develop
is covered in it.
