Since pool water Plumbing typically does not connect directly your home water system, the installation typically does not have to meet all state and local building codes. However, it is commonly considered a "best practice" to meet the building codes in the most reasonable manner.
That being said, PVC pool plumbing is typically installed in a fashion similar to that of an underground sprinkler system for a lawn with the pipes buried 6"-12" below grade.
PLEASE CONSULT A LOCAL POOLBUILDER FOR DEPTH RECOMMENDATION IF YOU LIVE IN A REGION WHERE FREEZING TEMPS OCCUR!
In regards to "which" pipes to bury, I would suggest that the more pipes that are buried, the less chance of accidental damage and the more professional looking the installation.
Hope this helps ...
building codes differ so check yours....and yes the codes apply to pools.....water pipe...8" to 12" inches below bond beam......high volt elect in conduit...18" ....gas line to heater....24"
I see no reason why you would insulate them. When you close your pool for winter you will purge (empty) your pump and pipes. The water in the pool would freeze long before the water will in the pipes under ground.
The spa can go anywhere if it is installed properly.
no,cause it will break
You should never completely drain an above ground pool. The chemicals in the vinyl liner that allow it to stretch when originally installed do not last. If you drain the water, the liner will shrink and when you refill the pool there is a good chance that instead of stretching back the liner will rip instead. NEVER drain your pool.
It can crack the pool and any pipes that has water in them that freeze. a way of protecting the pool is to float drums in a line along the middle of the pool there by leaving an unfrozen track along the middle into which the ice can expand. You should definitely empty the filter and exposed water pipes.
Ideally within 15 feet to minimize heat lose from the pipes.
You should not put any Earth in your 18 foot round 5 foot deep pool. You should only put water and cleaners in the pool.
You should remove the antifreeze with a shop vac if possible, antifreeze will not hurt the water, but is just one more thing in the water that you do not need to be there.
A good way to see if you have a leak in your pool is to # take a bucket and fill it with water from your pool. # mark it at the water level. # mark the pool at the water level. # wait a few days if there is no leak in the pool then the water level in the bucket should have reduced by the same amount as the water level in the pool, however if the water level in the pool has gone down more then the water level in the bucket you have a leak in the pool or in the pipes around the pool.
The plumbing system in a pool spa typically consists of pipes that connect the pool and spa to a pump and filter. Water is circulated through these pipes to keep the pool clean and maintain proper water circulation. The diagram shows the layout of these pipes and how they are connected to the pump and filter.

I'm not sure if it can be installed after a pool has been installed, try contacting a company who makes these hydrostatic valves and see if it can be done. good luck.
