I’ve been using a Hayward PoolVac XL with a Hayward Leaf Canister for years. Just purchased a new PoolVac XL and installed with new hoses. It is connected to a suction port not the skimmer. Now the hose gets hung up on the leaf canister when it passes underneath and will not move from a small area. Never had this problem before. Same suction and speed is set on the new PoolVac as before. Any ideas?
