2 FAQs on the Diaphragm for water control assy, Morco D51B and D61B/E


Hello i've a thetford cs200 toilet and i need to reduce the water that is pumped into the bowl the water pump on my boat seams a bit too strong chris P.s. do you also do spares for a morco water heater i need the bottom diaphragm as it tends to leak from the frost


The easiest way to reduce the amount of water entering the toilet is to introduce a restriction in the pipework leading to the toilet.
With regard to the Morco heater then we do have spare diaphragms, our ref. 125366.


Hi, I have a Morco water heater that won't heat my water. The pilot light is lighting and when I turn on the hot water tap the burner ignites and heats the water for a few moments and then goes luke warm/cold. Would you be able to tell me what could be wrong, I have been told that possibly it could be lime?

The problem could be water pressure or, as has been suggested to you, the heat exchanger could be suffering from lime deposits that are preventing a sufficient flow of water. Alternatively the diaphragm in the water control valve could be damaged such that the water pressure is unable to open the gas valve fully.
