Removal of head hoses from IP37

[Shelgail]

The hoses from the head to the overboard sea cock that go via an anti-syphon
loop have to be romoved because they are clogged. I spoke with
IP customer service and they said it was difficult and gave me a few
suggestions. Has anyone actually removed these hoses? I would appreciate
any suggestions from anybody who has removed these hoses.

Completed a full hose remove and replace on an 1995 IP40(#45) two winters ago. When we purchased the boat in 2002 we noticed that the "system" gave off some pretty pungent odors. We finally traced that down to the hoses. After a good deal of research and a discussion with IP about ties that may not be accessible (there are none) we decided to go for it. We used http://www.sealandtechnology.com/pro...ges.asp?pid=74 306342871 1-1/2 inch ID OdorSafe hose. A 50 ft roll was about $380 shipped. It's 100% PVC. It's a two-person job with a lot of push and pull but it can be done. We ended up pulling the old out trailing a pull line and using the line to pull the new. The old hoses were multi layer with a reinforcing wire to keep their form. You'll need a hack saw or heavy duty wire snips. The PVC is much more pliable when it's heated and we used a heat gun to "soften" it up to get on to valve nipples. We also took the opportunity to add a macerator and rebuild the heads. Good luck.

You say the existing hose are clogged. I assume that means with scale build up. If so...bofore you go through the process of replacement...may I suggest you buy a gallon of muriatic acid (Home Depot) and pump it through your lines till you see it coming out the through hull. Let it sit for about an hour in the lines. You may cure the problem for about 5 bucks!
(Note...the fume reaction when the stuff hits water is NOT to be breathed in...make sure you have good ventilation.)
