There is no way around pipes when building a pool. The further the distance from the technical room to the swimmingpool, the longer and more vulnerable the pipes are. The most ideal is a technical room that lies directly next to or underneath the swimming pool.
If pipes have to be burried, we would recommended that they are as easily accessible as possible. If the pipes are in a protective cover-pipe, they are better sheltered and possible leaks are immediately detected and can be quickly repaired.
I just don't understand why no pool builder takes this into account.
