My Kreepy Krauly hose appears to be pulling in quite a bit of air -- my leaf trap canister fills with air relatively quickly even when it's totally submerged, so it's definitely the hose that's leaking. I tried some of the generic Kreepy hose sections from a pool store, but they leaked even worse -- I could hear and even see the leaks, which appeared to be where the end couplings were glued to the hose. In other words, I don't think that it's the connection itself that's leaking, but rather the seal between the end pieces and the corrugated hose.
Is it normal for this to happen after a while? I don't know how old the hose is since we inherited the cleaner with the pool, but it appears to have gotten worse over time.
Are the "official" Kreepy hoses any better than the generic ones, and do they simply start pulling in air after a while?
