Scupper Clean Out

[gamecocks2001]

One of my deck scuppers is very slow to drain.  Is there a way to clean it out short of taking the inline valve apart?  That thing looks like it would be an extreme pain to get to.  I do have rabubs installed if that makes a difference.

Only other remedy other than taking it apart is flushing it with a hard stream of water and hope it unclogs. Mine were the same way, it's annoying!

High pressure will not get them cleared. You need a large volume of water to flush them. Yes you need some pressure but not 1000 lb. Find a funnel that fits the inside and cut and attach a hose. Turn on all the way and use a rag if necessary to seal.  Putting some dawn in and letting it sit will help.

The other option is a shop vac. Remove the raybuds even above take them off.  Rig the vac to fit the transom. Put some dawn down then cover the grate. Fill inside of boat with a bunch of water. Remove the rag covering the grate and cut on shop vac. This will pull a large volume of water and the trash.

I use a gas powered leaf blower.

I've used air compressor with around 65 psi and pointed nozzle.....to push the water and soap through it. I guess it depends on what is actually clogging it up.

I eliminated the check valves and installed Rabuds, no problems.
