External Strainer for Head Intake?

will be pulling the boat out next week and install t-hull for a permanent head and was wondering if it is wise to install one of those strainer cups over the t-hull on the outside and if not do i need an inline strainer before the toilet on the inside?

thanks
Ben

Normally it is not really needed. You could install one on the outside.

I couldn’t imagine bringing sea water on board with it going through an inboard strainer.

A scoop might force water past the head valves when underway, and flood the boat.
IMHO, don't put a scoop on anything that is not constantly discharging water.

No scoop on ours either. Never a problem.

I think an in-line strainer inside could be useful. I've had to take the head pump apart once to clear out weeds that got stuck in a flapper valve. Would have been a lot easier with a strainer.

i have an inline strainer mounted between the thru hull valve and the head. it's cheap enough insurance to keep the line into the head relatively clean. might prevent having to take it apart at sea - might also help to keep smelly decayed plant life out of the head as well....

It probably all depends on where you live and the amount of free floating stuff. In my area a strainer is unnecessary.
