Redesigning my plumbing for a heat pump. Is it better to put a Wye and 2 ball valves, or one 3-way valve? (to heat pump or to pool). Two Jandy 2-way cost more than one Jandy 3-way, but it seems a 3-way would be more restrictive. Much cheaper if I use red handled valves since I probably will hardly ever have to take them off heat pump. Most of my joints seem to be two 45's rather than one 90, will stick with that for corners.
