I have a cheap DRUMMOND 1 HP Cast Iron Shallow Well Pump With Pressure Control Switch. I have 6 zones on a 1/4 acre lot with only 4-5 heads running at a time. The pump had not run in a few months and it was failing to prime so I called a sprinkler and irrigation company out to fix my sprinklers. It cost me $400, he removed my pressure tank, replaced my sprinkler timer and wired the pump directly to the timer to turn on/off and draw water, replaced check valves. He never mentioned any potential issues with the size of the pump. The pump is intaking 50psi if the discharge is shut off to the sprinkler heads, but drops to 10-15psi when water is going to the sprinklers. Now the guy is telling me I need a new pump and that this one is not large enough.
Questions:
1. If I had a pressure tank still attached would it resolve the lack of psi? Is this going to burn my pump up even if i buy a new pump?
2. If some of the heads were clogged/leaking would this cause that significant of a drop in pressure? Trying to decide if I should try replacing all the heads prior to getting a new pump.
3. Does it sound like I need new pump?
4. How bad did this guy rip me off?
