Hi
Were about to get our first pool now our kids are confident in the water.
Weve seen a 6m x 4m below ground pool at a local supplier with an aboveground spa which spills over into the pool. Ive been reading up from this website, Dryden Aqua, and a few other sites to produce a scope of what I think we want and which I can provide to a few of the pool suppliers for a quote. By doing it this way Ill understand the system and the functionality.
Id be really interested in any feedback on equipment setups, piping, setouts, lessons learnt etc which others have done and are happy to share. PS were in Perth Australia.
-Were currently not planning on having a separate gas heater for spa, but then it eliminates spa use during winter so rethinking the idea.
-If we go fibreglass pool, pool suppliers here typically only use surface skimmers and not floor main drains due to access incase of leaks. I guess a main drain could be added in the lower side section of the pool wall or isnt this an issue?
-Are we best going a pump for the pool and laminars and another for the spa? If we end up having a swimjet that on its own system anyway.
-Does the spa require a skimmer given its spillover type?
