Last week I was told by my pool cleaner the Pentair Intelliflo pump was leaking and would need to be replaced with a new pump. I checked the pump later and found 5 of the 6 housing bolts were loose. I tightened them and the pump no longer leaks. The tight bolt was the hardest bolt to reach. The owner of the company came out today and said these bolts can work loose. He did say the cleaner should never have told me I needed a new pump and should have inspected the bolts. It doesn't seem right to me that only the easier to reach bolts worked loose on their own. I have had 3 pools over the years and this has never happened before. Has anyone ever had these bolts work loose before?
