Blocked through Hull fittings

[Gary Ryan]

Guys, my fresh water overflow and I believe my Sump Pumps through hull fittings are blocked. I suspect spider webs etc. Anyone have a good way of clearing the lines?

I'd be more apt to believe Mud Daubers rather than spiders.

I HATE mud daubers

First time I've ever heard of them. Any tools/utensils that I could insert and clear out?

One time I was successful when our raw water inlet was blocked. I disconnected the hose from (in my case the strainer)
and held a cut off piece of hose tight against it and turned on the water. It worked great. The reversed flow did the trick.

Blow them out.. For Ken.
Water, Reverse flow of vacuum cleaner, or air form a compressor. I here even your boat horn can be used to blow air into a pipe and blow any stuff out. (Never tried it, but in a pinch one gets resourceful.)

That worked. I used a shop vac....all good now! Thanks for the ideas.
