Hi. We have an older style whirlpool/jetted acrylic tub. The Aqua Flo pump
was installed on the subfloor and at the foot of the tub within the wall
enclosure. When we are using the feature the roar of the pump is almost
deafening. Even though there is access to the pump via a small wall hatch
in the wall, tearing down the walls to gain good access for sound deadening
insulation is not worth the bigger hassle to me.
Instead, I am thinking of moving the pump to the crawl space directly below
the tub structure, about 4 feet vertical. I figure this should solve a good
part of the noise problem and thus make the tub more usable.
My preliminary plan was to mount the pump on a concrete block (in dry warm
cement crawl space) and run 1-1/2" reinforced braided vinyI hoses back up to
the copper plumbing at the tub (inlet and jets) using sch80 pvc insert
Because of the pump's low pressure/ high volume and relatively low temps
generated for the bath, I figured the braided vinyl stuff would be
acceptable. The hoses should also keep sound transfer to a minimum.
However, I need to know if there are any other special considerations (check
valves (priming), water lift problems, potential motor damage, etc) in
mounting this pump below the tub and/or whether this process would work
properly at all.
Thanks for your suggestions.
