Kinda strange but I need a good answer. I bought a new hose for vacuuming out my pool. It's about 6 feet longer than the old one. Same interior dimensions, just a little longer. Could this lesson the amount of suction? I have backwashed and closed the main drain, but I just don't get a lot of suction. Maybe a new impeller? It's only 2 years old, but ..... I wouldn't think a longer hose would cause this issue, but I have to ask.
