Help, We had a new pump and sand filter installed last year. last week twice the heavy rubber hose from the pump to the filter blew off draining the pool below the skimmer intake. I replaced it and clamped it tighter. 2 days later it blew off again. I assumed I hadn't gotten it down all the way on the pump pipe so I greased it with Vaseline and pushed it sown all the way and clamped it tightly again. Next day it was off. Lots of expensive water wasted. I need to know why it blew off in the first place and what to do. My son told me it had done the same thing last year but he hadn't told me but just shoved it back on and tightened the clamp. The clamp is the slotted metal sort with a screw that one must turn to tighten it. I need all the advice I can get. I do not have great amounts of physical strength as I am 67 years old.
The pool man I consulted on the phone told me to get all the grease off and put the hose back on and try 2 clamps.
