Clear corrugated suction hose (was) Bilge Pump Upgrade
It's reinforced. The inside is like regular hose with only the
slightest irregularity from the outer reinforcing ribs slightly distorting the plastic as it set. Absent the reinforcing ribs, it's about as thick as clear plastic hose but appears to be a tougher material. No wire in it but it would take quite a suction with the ribs. I bought this stuff at Hamilton Marine and the box said bilge pump hose. (They also had the cheap, truly corrugated stuff.) I think it's OK. BTW wire can cause it's own problems. When we first tried to start the engine of our new boat, the cooling system was sucking air. We spent hours trying to track it down. It finally turned out to be the connection at the strainer which was very hard to see. Even though the wire in the hose was stainless, the end had touched the bronze strainer body and the electrolysis had degraded the rubber. Fortunately, the seller was paying but that cost him about $250. Here's a photo: http://home.maine.rr.com/rlma/Hose.jpg No choice but to have wire when there is going to be any significant suction but this is something to watch for when you are cutting the wire while trimming hoses. Don't let the end of the wire stick out where it can contact other metal. -- Roger Long "Peggie Hall" wrote in message om...

If it's rated for the application--not only for below waterline, but for whatever goes through it and the temperature of it--it's ok. If it's not, I'd replace it. -- Peggie ---------- Peggie Hall Specializing in marine sanitation since 1987 Author "Get Rid of Boat Odors - A Guide To Marine Sanitation Systems and Other Sources of Aggravation and Odor" http://shop.sailboatowners.com/books...ku=90&cat=1304 |
