I see a few of these a year.
I have recently come across this problem where The Pvc pipe is being split like there was high pressure. Ive used this well for many years with no problems. In the last 3 months Ive had to pull the pump out cause I lost water do to this strange accurance with the pipe being split like as if it had been stretched and bursted. The burst on the pipe is up about 1-2 feet from the pump. Again this is an in well pump 200 feet down. Thanks for your help and replies.
My guess is that you have more than one checkvalve and that is causing water hammer.
it expands like this on the black pvc pipe at the bottom of the well. Above the threads tho. 1 foot above the pump. Do you think its the pipe or the pump doing something strange
If the pipe is swelled, I would say that the pump is running dry and turning what little water there is into steam which is then swelling the pipe.
I would do a simple yield test to find out how much water your well is making.
If the pipe were not swelling I would agree with LL, as a split can also be caused by having too many check valves.
I've seen my fair share melt off over the years , but never seen one bubble pvc like that.
This one was on a Sub Drive 100..... The first one on a 1 hp with a QD pump tek.
This is what happens when the pumps run long enough to create steam in a weak well. In both cases the wet ends were wiped right out.
Valveman, both of these jobs had pitless adapters buried 4+ feet.
Pretty damn amazing
yupp. Same thing happened again , pipe swelled and bursted just like this picture. yesterday was not a good day at -20 pulling the pump outta the 250 foot well. Thanks for great information. We now lowered the pump an xtra 50 -60 feet down. hopefully it all is good.
