I’m looking to add a stand alone solar heating system to my pool. I would like it to be completely independent to my filtration system, so that I can run both systems to their optimum. I have upgraded my pool from 32 to 38 mm fittings, so am happy to cut the liner, however, that was done over an already reinforced area. So my question is ; has anyone added new inlet/outlets? Did you reinforce the area prior to cutting, if so what did you use, how did you find it worked. Thanks in advance for any replies.
