A few years ago I bought a 1HP Myers pump and a 30 gallon pressure tank from you guys with lots of help (thank you) picking what I needed. I think I scrimped on the tank and it is undersized but perhaps that is a different issue. We installed the pump and tank with 1" copper line running first through a softener from Sears and then split to to HW tanks and to a manifold on the wall with PEX plumbing from there throughout the house (4 showers and 5 bathrooms).

The problem is that in the bedroom next to the mechanical room in the basement, the sound of the system when it kicks on and starts pumping is so loud you cannot sleep if it kicks on at night. It is actually louder in that bedroom than it is in the mechanical room itself. It gets quieter as the pressure tank fills but the initial sound is loud and has a sound similar to rushing water and pump noise mixed together. It is not water rushing through the pipes outside the mechanical room. Pressure switch on pump is set to 40-60 and 38 lbs in tank empty. Pump was not bolted to floor so I bolted it down and it made no difference in sound. Placed pump on 3/8" rubber pad and bolted down - no difference. Supply line is NOT attached to the wall - I removed the attachment points so it could not vibrate in the wall.

Is there a quieter way to install or system to buy? Tank is metal tank (Blue). Wall is insulated between mechanical and bedroom - didnít help either. The manifold is on the common wall but the sound does not come from that area - and with the softener in between pump/tank and manifold I donít see how any vibration or conductive noise could be getting to it any way. It is just very loud when pump starts and tank starts filling. Any ideas - I am at a loss but right now the bedroom is un-usableÖ...
