How can I keep the hoses on my (above ground ) pool filter from blowing off all the time?
Question:This question is actually for my friend, who's pool we were swimming in over the weekend.All of a sudden a hose on her pool filter blew and we had a fountain in her backyard. She quickly shut it down and then told me she has put two clamps on it and it still does it almost every week.Can someone help?
Answers:
Not knowing if the pump is a positive displacement pump or not I would suggest that you make sure the discharge side is free of any obstructions before proceeding.
Assuming the connection size and the hose size are compatible, this sounds like the clamp is losing its grip.
Worm drive clamps are subject to loosening under vibration, such as in applications on a pump.
Sound familiar?
The first person to talk to is the system supplier, as they may encounter this on a regular basis and have a standard fix.
If not try some better clamps, making sure not to create so much torque tightening the clamps as to crack the connections, which I assume are plastic.
I would suggest moving up to a Constant Torque Worm Drive Clamp, which should be able to compensate for any thermal changes (It is hot around the pool isn't it?). Use TWO clamps per connection stagger the locations of the Worm Drives so that they are 180 degrees apart and facing in opposite directions, this should minimize any potential for leaks that might be lubricating the connection point and help insure the clamps stay in place.
If these do not hold the next step up would be using Constant Torque/Spring Loaded T-Bolt Clamps, which will hold even more torque and come in wider band widths.
Good Luck
Stainless steel radiator type clamps will usually hold. It sounds like her filter is plugged up and causing extreme pressure to build up. Only other thing I know of is to change the inlet/outlet adapters to the hose-barb type and they still need clamps.
