I recently had the hose that runs from the seacock to the strainer replaced. It's 3/4" Hose and had been the cheap
clear reinforced plastic or PVC hose. The tech. used a black wet exhaust
hose. It is smooth inside, but after only two months in use (full time live aboard in brackish water
in the Texas
heart), the 4' length between the seacock and the strainer had completely clogged with algae. I was able to blow it out, but this does not seem right. Is there a better hose for this application? Needs to be 3/4" ID.
