Hi. A plumber installed a 2hp jet pump as a booster pump less than 1 year ago.
It ran fine until a few weeks ago when the pump outlet to bladder connection blew off and all the water in the bladder gushed out. I quickly shut off power and investigated.
I found that the metal outlet of the pump was so hot that it caused the pvc pipe connected to it to blow a leak and release the bladder pressure.
I read this forum for help and measured the voltage. I found that the voltage at the pump is 247 volts (the pump is rated for 230).
I replaced the blown pvc pipe (1-1/4") interface to the pump and replaced the cut in/off switch as the contacts were pitted.I used a 30/50 psi switch. I checked the bladder pressure and it measured around 40 psi-which was 12 psi too high so released some air and now it holds water(feels heavy when I rock it and releases water when I open the downstream valve. I also brought the bladder (82 gallon) within 2 feet of the pump as I read that at 4 feet you can cause chatter on the points. I used the diagram in the manual to postion the bladder downstream of the pump and upstream of the house.
Now when I start the pump it does create pressure on the output (I put a valve inline after the bladder but before the house) but when the pressure gets around 55 psi the output pipe warms up. Therefore I adjusted the spring loaded breaker to trip off line around 55 psi.
That is OK but I remember before all this happened, the pump would cut off around 72 psi and provided more pressure to the house.
The well has a separate pump and it fills a 3000 gallon tank that is up hill from the booster pump in question. It has good gravity flow and I have a valve with a hose on it to allow water usage in case of emergency.
So, am I asking to much to get more pressure out of this pump ? and is it normal for the pump output to start getting hot to the touch at 55 psi? What else can I check to verify everything is normal?
