Pump Preassure after replacing new pump
I just replaced my 3 horse power pump. the system works but the pressure is not like it was last year. The system was winterized by a guy I thought I used the year before. I started up the system and the first zone came on but the second never came on. I replaced a broken line and then started the system It still didnt work right. I replaced the 3 HP pump and the preassure is still not good. What can it be? I have some knowledge but this has stumped me !!! Please Help
