Had a starite 1hp pump for 30 + years which sat ontop of a large bladder tank & was reasonably quiet.
Have a j10s now on top of new bladder tank & it is noisey compared to the starite. Want to move the pump to the slab figure it will be less noisey than sitting atop a 20 gal bladder tank but wundering should I bolt the pump directly to the slab or bolt it down with rubber between pump & slab ?

I have my J5 bolted directly to the concrete floor in my garage. It’s very quiet. I thought about the rubber too but did it without figuring I’d test it first. I can always put the rubber in but truly I don’t think it could be any quieter than it is.

Thanx for the reply; was also wondering that taking the pump off of the top of the pressure tank & bolting it to the slab puts it 3 feet closer to the static water level of the well would there be a noticeable increase in the gpm ?

You could probably measure a difference but I doubt it’ll be big enough to visibly notice it. It surely won’t hurt anything as far as flow rate. I have a PK1A system with a CSV. The tank is only 2 gallons. Awesome system. My pressure switch is 40-60 but the water pressure at the faucet, once it drops to 40, comes back up to 55 in a few seconds. Then stays there for as long as I’m using water.

Noticeable? Maybe, but probably not. If your static water level is fairly low or falls much as you use water, then yes.

Lower the pump the better. Sometimes it is more the hard piping to the pump that makes noise than how the pump is bolted down. A flexible hose like theStainless braided type will take out the vibration noise.

Are you talking about the hard piping on suction side of pump or discharge side. I have a 1 inch pump connector I was going to use on discharge side of pump.

Usually just a flex line on the discharge side will stop the vibration from transferring down the line. But sometimes a flex line is also needed on the suction side.

A flex line on the suction side of the pump would make it eaiser to connect / disconnect and I have a falcon stainless 1.25 mip / fip that would work nicely but can they take vaccume as well as pressure ?

Yeah those should work fine on the suction, but are rigid enough they may not isolate the noise. Rubber suction hose would be best.
I have spent a great amount of time trying to find a 1.25 hose that will work just can't seem to locate, all I would need is a 4-6 inch piece and use a couple band clamps. have allways had hard piped to the pump & if I needed to disconnect would have to cut pipe do what I needed to do & then reinstall using a coupling and glue. Would much prefer very short piece of hose and band clamps. Have only found rolls of 20 feet to buy and then I could cut a 6 inch piece off that -- too expensive that way. Maybe you have an idea how where I can procure a short piece.
