I recently bought a Pool Cleaner (The Pool Cleaner, 2 wheel suction model) and decided to add a Hayward Leaf Canister (w530) in the line to catch the large debris on the bottom of the pool. The problem I have is that after about 30 minutes of operation I notice air building up in the canister and if I do nothing eventually the air pocket gets so large the return to pump starts sucking air. Sooo..I started troubleshooting this and realized it wasn't coming from the seal on the canister--the canister starts building up this air volume even when the canister is completely submerged (so it's not the o-ring on the canister). So the only thing it can be is the connections between the pool hoses that run between the cleaner (or they have a leak) and the canister (tried swapping around several of these to no avail). My question is--is there anything I can use to "seal" the connections between the hoses (the hoses are new and came with the pool cleaner--although they do look really cheap)? Any guidance appreciated.
