I have a grundfos sqe constant pressure well system that provides water to my house along with my irrigation system. This is combined with a 2 gallon pressure tank. We used to have a larger pressure tank with the system, but that caused issues with the constant pressure, so our well company replaced the tank with a properly sized one and now the system works great. The only issue is that when the irrigation system turns on, there is so much water leaving the house at such a fast rate, that we lose all pressure in the home for 5-10 seconds. Is this okay for my plumbing to endure these drastic pressure changes, or is there something that I should do to fix/prevent this? Are there any solutions out there? Perhaps a slow open master valve for the main line?
