I just installed a new pump and pipe in my well. I replaced a 3/4 H.P. pump w/ a 1.5 H.P pump and intend to use for automatic sprinkler system. I ran a test with the well and at 50 PSI at a water level of 60 ft and I was getting 22 gpm with the unit. This test was just letting it run onto the ground. I connected my pitless and connected the plumbing to a hose spicket. I restarted the pump to check for leaks on the pitless and noticed that a stream of water started to shoot up around the casing of the well. The top of the pitless appears to be dry. I do not know the type of pitless it is but it is the same size of the casing and has two rubber seals on it. One on the top and one on the bottom. The water enters the underside of the pitless and is forced between the two seals to the pipe leading into the house. Any suggestions to stop the leak on top around the well? Is my casing split? Or do I have a bad pitless? Thank in advance.
