I am having a SWG installed by a professional and would like them to plumb my system for a future DIY solar project.
I am putting in a Pentair Easytouch with IC40 SWG. For the DIY solar project, I Plan to purchase an above ground system and just feed low pressure water through it directly back into the pool bypassing the SWG (between gas heater and SWG). To do this, should I put in a T with a 2-way valve, or a 3-way valve? I think the 2-way valve may be better so I can better control the flow with how far it is opened by the Pentair actuator, and not close out the main return to the pool by accident. This setup currently exists, but with a cheap valve installed by the previous homeowner that has a garden hose connected.
