Simple Solar

Today I replaced 200' of 3/4" polypipe tubing in my solar water heating panel after about 12 years of abuse. I originally used the cheaper (100 psi) tubing to save money and it started to spring some leaks in the last few years. Replaced with 160 psi tubing and gave it some fresh flat black paint.
The old polypipe will be repurposed in low-pressure gardening applications. Free hot water season is back baby!!
