how to construct a sand filter for a pool?

Answer 1

You could build one, but it would be cheaper to buy. A sand filter is made up of a multiport valve, tank body, latteral assembly and sand. You'd have issues constructing the lateral assembly most definitely. It's a precision part. The holes can't be to big to allow sand to get through, yet have to be large enough for decent water flow. It's a fine line. Don't forget, the entire assembly also has to be able to withstand an internal pressure of up to 30 psi without failing. Buying one makes a lot more sense and less frustration factor for you.

This is for KeKe: Don't think for a minute, that going salt will reduce filter run time. You still need to turn over that water. Going salt will save you money in the chemical department is all. Don't get me wrong, I love those units, just don't buy one thinking you can start running the filter less. Bad mistake and one of the reasons that some people that have gone salt, complain that their water goes green. The unit is doing it's job only when the filter is running, but the filter isn't turned on in their case, hence no chlorination and filtration = green pool
Additionally, two filters going bad in two years is something I've never seen other than in filters that weren't winterized correctly ( destroying the laterals or standpipe) or the bad habit of turning the multiport, while the pump is still running blowing out the keystem gasket and internal pressure bypass gate. It's not due to run time.

Answer 2

Essentially its a barrel full of sand with a pump and a filter to keep the sand contained.

I'm sure you can make one if you can come up with a good enough filter to keep the sand out of the pool. But I'd suggest just buying one. It's year end so you may be able to find a good deal, or even a used one.

Answer 3

I would recommend buying a resin filter from your pool supplier. These work better than traditional sand filters, and you don't have to mess with recharging the sand. One charge will last a couple of seasons depending upon how well you manage your pool chemistry.

In addition, if you install a sand filter yourself, you will have to buy the multiport valves and pvc pipe to line up the system. I just replaced my sand filter with a Hayward resin filter system. It took two guys 2 hours to pull out my old metal sand filter and install the new one.

Answer 4

Is this for an above ground or in-ground? If it's above, you can probably do it with a search on "how to" --with the right size pump; however, if it's in-ground, I just don't know if you'll get the long-term results you want. We have a 30,000 gal in-ground, and our sand filter (professional) has been replaced twice in 8 years. We're thinking of going to salt-water system to reduce the need to filter as much. Wish I could tell you how, but here's some info on a site below:

Answer 5

you have to buy the filter from a pool supply store.You really need somene to install it.

Answer 6

Buy one
