Hi all,

I have a Beneteau 473 and have, what I hope, is a simple problem. Most all of my pumps on board are protected by Jabsco Course Mesh Pumpgards. In the forward head I noticed this weekend that my shower drain was working slowly and the pump was laboring a bit. I can see that the pumpgard is likely clogged. As I tried to unscrew the pumpgard it would just not budge. Given that it is plastic I did not want to try to force it. And being under the sink it is a bit awkward to get at.

Any advice on how to get this open without destroying it. Any tools in particular that would be helpful in twisting this off without damaging the cover?

Small oil filter wrench?

Perfect. I think I can get this around it. Others have suggested heating with a hot rag or hairdryer. That combo should work.

Be careful with 'heat' on plastic components as they begin to 'soften' at about 180 deg. f.
Next time you open the strainer be sure to 'lubricate' the seals/gaskets when reassembling .... will make the disassembly easier in the future.

After you've gotten it off and cleaned it up...

Keep your shower and sink drains and sumps--and strainers too--clean and sweet smelling by putting a few ounces of Raritan "C.P. Cleans Potties" into 'em once a week when it can stand at least overnight. Raritan only markets C.P. as a toilet bowl cleaner, but it's also the best sump and drain cleaner on the planet! C.P. is a bio-enzymatic cleaner that not only destroys odor on contact, but the enzymes in it "eat" hair, soap scum, grease, body oils etc that clog pumps and screens. And using it is one of the few jobs that doesn't require any manual labor:

Sumps: Make sure the sump is about 1/4-1/3 full of water...put 2-3 oz of C.P down the shower drain. That's it. When you come back, run plenty of clean water through the sump to rinse it out.

Sink drains: close the seacocks...put an ounce or two of C.P. down the drain...fill the drain with water. That's it. When you come back, open the seacock and flush out the drain with clean water.

C.P. can sit in drains and sumps indefinitely without any problem--although it ceases to accomplish anything after about 24 hours...so no rush to get back and flush it out. Use it once a week, or just before the boat will sit each time and your drains and sumps will stay clean and screens clog free.

And btw...it's also an outstanding toilet bowl cleaner!

p.s. Hey Rich...Your scalp starts to do worse than soften at well below 180F...so he can use a blow dryer on it if he's careful with it. However, I'm not fan of heat guns because it is too easy to do damage with one.

Good advice on CP. For 'jammed in the open position' seacocks, get some 'plumbers putty' and dive under the boat to 'seal' the problem throughull with a small wad putty. From the line suck out 'most' of the water, then add CP to the line and simply wait for several days for the CP to 'work'. Clear the line of the putty with a 'plumbers helper'. Most times after such a 'treatment' the seacock will turn 'free'.

Hi all,

Thanks for the advice. Got to the boat this weekend and used a small strap wrench. The strap wrapped around the pumpgard just fine and worked great. Turns out the pumpgard was not stuck or bound ... I just did not have enough leverage in the confined space under the sink to us my hand to undo it. It was really just a bit more than finger tight.

Filter was completely clogged ... mostly with what looked like lint from the towels.
