We're having a new pool built soon (see http://www.troublefreepool.com/new-p...az-t54925.html) and have a question about the plumbing. We will be having an in-ground cleaning system installed (we're 100% set on that) but we're also asking for a dedicated suction line to be installed, just in case we want to use a vacuum at some time. Regarding the returns the PB said they'll put them in if the in floor valve has an available zone. Since we have a pool and spa and a few benches the in floor valve may not have room. Theoretically, we shouldn't NEED the returns because the circulation can/will be done through the in-floor valves.
Do we really need returns? What if we don't have them? Thanks!
