I broke the union nut on my pentiar pump. I decided to just build a new connection from pump output to filter input. Previosly the pipe was a straight with (2) 90 degree couplers. In reading about pool plumbing I saw that hard 90 degrees couplers shouldnt be used. Instead to use the 45 degree couplers. I only need to go about 2 feet from the pump to filter. I was just wondering what the professionals would do in this instance? Also any tips on getting the mesaurements right. I tried to fix the old pipe by cutting the broken section out and cementing on a new section but I found that when you dry fit the pipes they only go in about 75 percent of the way where as when you have the primer and cement actikng as a lubricant for few seconds the pipe will seat all the way in the couplers. Anyhow my attempt to install the frankenstein pipe wasnt fitting flush so that is why I am starting from scratch.
