Crazy Question

[TROUBLE]

My friend just bought a silverton motor yacht. When he flushes the forward head it brings in salt water and waste from the holding tank. Is this possible and is there a common place to look or a common part that fails. He doesnt know what type of toilets they are. All I know is they are electric salt water flushers.

I was on the boat last night and the smell when someone flushed the toilet chased me off the boat.

thanks

Your friend needs to check the valve from the head to the holding tank. It is a non-return (of-course) and called a duck-bill valve. They fail quite often and I used to keep a few spares on my previous boats.

Check that the seacock is open and the strainer is clean on the head intake.
