I have a grundfos sqe 1hp pump that was hooked to a CU301. I have just converted it to a PK1A cycle stop valve kit thinking maybe my controller was telling my pump to act the way it was. I have the same concern on both the CU301 and the CSV. My concern is that when you turn on water (lets say the shower) the pump starts running but the pressure drops slowly from 70psi to 40psi and then when it reaches 40psi it drops drastically to 20psi and stabilizes at 20 and does not climb until you shut off the water, if you run a shower and turn on a sink at the same time the pressure hovers between 10 and 20psi but I never really run out of water. My well was punched 4 years ago and I was with the well driller when he hit water at 304ft he continued to 340ft. My grundfos sqe 1hp pump was set at 240ft. He put my well flow at 35+ GPM. I live in a very rural area with very few people for miles. This is a new development. My system used to work well and keep a constant pressure near 70psi with the CU301 for years. Lightning did take out my controller twice in the past 4 years and they are not cheap. The last controller I installed was about a year ago.
The only thing I can think of next is the pump. Does this sound like a pump going bad? If not, what are your thoughts? If so what would be the best replacement pump for my situation? I have 7 kids, a small hobby farm, a garden, and a pool so I use a lot of water and I don't want to replace my pump every 4 years and I want the absolute best performance and reliability that money can buy. I have already dumped enough money into this system to buy several pumps.
My grundfos pump is model 10SQE10-290.
