Toilet flush problem

How about fitting a simple shut off valve in the line bteween the pump and the bowl and switch it off after use

If you mean instead of a vented loop, you'd have the same risk of flooding the bowl when the boat is at rest if you or a guest leaves it open as you'd have without it. Any shut-off valve should be in the line from the seacock to the pump and/or head discharge line and should be in addition to vented loops. And should never be used as an alternative to closing seacocks when leaving the boat, only while aboard.

Re: Toilet flush , now fixed with boiling water.

When this happened on our loo, being only six months old and subjected to fairly light use, I refused to accept that it needed a service kit. Instead, the gasket was removed and soaked in boiling water with various crocodile clips holding the valve in such a position to correct the 'misalignment'.

Spot on that man. My Jabsco toilet was only a year old so I followed your instructions and now the inlet water flows without a hesitation.

Having taken the top off the pump and looked at the distorted section of rubber I was appalled at the general crappiness of the design. All it took was 15 minutes in simmering water with the valve flap held in a reverse bend by a plastic pincher clamp.

Jabsco must have degenerated in a malfunctioning corporation if it continues to ship a product with a manifest low tech design error now well understood by suffering customers.

My next heads project is to install a small loop on the inlet pipe between pump and bowl to being the top of the inlet circuit above sea level when heeled. Once done I think it would be safe to leave the heads in the flush position and the inlet open while on the boat.

I do not see the need for a siphon break as my toilet pump is about 1 ft higher than the inlet seacock, but I am happy to hear counter opinions.
