I have a TMC Dry Bowl 999 manual heads unit.

It has a two way lever (OPEN / CLOSED) and a manual hand pump.

Being a little naive, I have no idea where the lever should be whilst being USED / FLUSHED or in STANDBY mode

Does anyone have access to an instruction book, know how to use one correctly or point me towards an owners guide anywhere (Mr Google has failed me so far!)

Many thanks in anticipation.

In one position it will pump the waste out of the bowl. In the other it will also draw in water from the inlet to wash the bowl. Easy to see which is which looking in the bowl - although if it has not been used for sometime you may find the flap valve stuck on the inlet. If with the lever in the flusjh position you can pump with nothing happening you need to strip down and make sure all the valves are free.

This would seem to be the problem. No matter what position, the bowl empties, but does not seem to 'flush'. Although there is a lot of pressure on the pump handle there is very little amount of 'flush' water entering the bowl.

There is probably a separate stop valve on the inlet skin fitting which could be closed?

Make sure the stop valves on both inlet and discharge (unless holding tank) skin fittings are open.

It doesn't look much different from most marine toilets. Check that the seacocks are both open and flowing. If it still doesn't work you will need to open it up to ensure everything is functioning.

Longer term: This ancient thread suggests that a Jabsco pump will fit the base. Might be worth considering as you are most unlikely to be able to buy spares for it.

This seems a problem I have too. :(

Fresh in my mind because used the loo for first time this season over Easter. Would not pump in water. Took the top of the pump of cleaned the little weighted flap valve on the inlet. Problem solved.
