Hello,
I have a pool pipe that goes from my skimmer to pump. It sprang a leak. The pipe was copper about 1.25 inch diameter. The pool company cut off the pipe at the leak (around 1 foot from pump) and fit on a larger diameter PVC pipe with some type of transition coupler over the copper pipe. Now I have a constant supply of air in the line, could this be cavitation cuased by the larger diameter pipe or would this cause some other type of pressure change that cuases less water to be sucked into the pipe. <b> Thanks </b> Would the problem be fixed if I have a constant diameter of pipe ?
