When we don’t use the boat for a day of two and then pump in sea water to the toilet, we get black particles in the stagnant water in the transparent inlet pipe which smell strongly of bad eggs when they get in to the bowl. Does anyone know what might be causing this and how to prevent it? It is as if something in the sea water dies and decomposes when left in the inlet pipe.
if you got ot hints and tips on main site ref heads (smelly heads )there are photos of how to cure the smell have done it to two of my boats and have not had the problem since the cost is small the time it takes is minnimal the problem solved all parts can be sourced from the local fish pond shop.
I sent email to readers letters in Yachting Monthly egarding smelly toilet, and received interesting reply, aparently smell is caused by sea life in the inlet pipe which die when seacock turned off and left for several days, the cure is to dissconect the inlet pipe from the seacock, insert a tee piece into the oulet pipe from the basin just above the seacock, and connect the toilet inlet pipe to the tee piece. To operate the toilet flush you need to fit the basin plug, and when you leave the boat fill the basin with water from the tap,turn off the seacock and then flush the toilet using the water in the basin, this removes any sealife from the inlet pipe to the toilet and leaves it full of fresh water, then when you return and use the toilet there is no sea life to die in the pipe
