Just a live and learn here guys. I went to the pool store---got everything I thought I needed to hook up my pump and filter. The owner of the store cut me some flexible PVC to hook up between pumpo and filter along with 2 threaded to smooth fittings. This will NOT work. I learned the hard way.
Only threaded to barbed fittings will work. I dont care how many clamps you put on, unless you have a very weak pump the clamps are not enough to hold the PVC hose on and keep it from leaking.
When i told the original pool store my issue they said I would have to get a plumber---essentially not their issue. Dopes. How some of these guys in pool stores are able to operate with so little knowledge of their business is beyond my realm of understanding.
