Pump/Filter base ? - Contractor Talk - Professional Construction and Remodeling Forum

As some of you know from another thread in another forum, I am having my lined pool renovated.

Work will include new skimmer, returns, and lines. The filter/pump will be relocated into a soon to be installed pool house.

I do not plan on having a slab poured for the pool house. I would like a framed floor (w/ PT ply flooring) sitting on blocks.

I asked my pool guy what he wanted ready for a base for the pump/filter - I must have been unclear with my question because his answer was not relevant - or I misunderstood him.

So I ask you guys, what would you want to put the pump/filter on. (sand filter this time)

Can it go on the wood floor of the pool house or does it need a concrete pad ? If concrete, how thick ?
If concrete, does the pad need to be relatively level with the pool house floor, or can it be a few inches lower?

TIA

We use prefab lightweight concrete equipment pads. They come in standard sizes like 2' x 3' and 4' x 4'. We get them from the pool wholesale house, but I have seen the same type slabs used for HVAC equipment.

The elevation needs to be high enough that the pump won't flood. Never used wood but it would be a big hassle when you had to replace it.

i don't use pre fabs - i hate em

i might have an idea for you da arch - you're basicallyy just having a block foundation and the pool house framed on top of that - right?

so you'd have a crawl space??

A pad is the only way to go. Have you done any weight calc's on a sand filter full of water? The last one that I did a pad for was 3600#'s. It WAS a big pool and we live on sand.

Dirt Diggler,

Yes and no. Blocks - yes. Foundation - no. It's just a small pool house - actually a shed - 8 x 10 is the only size we can fit (and afford). Blocks will be used to support and level corners. No crawl space, unless you're a chipmunk. The floor will be approx 10" above grade.

Teetorbilt,

ALMOST 2 TONS !?!?!?!. WOW, I had no idea. It's a 20,000 gal pool. Filter will be a 20 inch Hayward sand. Pump is not heavy - 30-50 lbs (?).

The old DE filter was what? 200 - 300lbs WITH water???

But that's why I asked you pool pros. You know the business. I'm just a paperhanger. I know walls - you know pools and equip.

20" tank - 250 sandlbs + 40gal (@ 8 lbs. per gal 320). 570lbs

4x8x4" pad plenty to hold that set up & room to retro a heater in the future. ask you installer to bury a "dumby" set of lines & punch new 1408s in panels. so when a line breaks (& one will) you just have to cut the liner at faceplate & tie into the pipe stub @ filter area, or you can rip up the new deck for a repair if you prefer. any ?s
