But as the preferred place to stick them is in the water outlet side , they do tend to have extremely hot water flowing through them .What temps are those plastic hoses and fittings rated for ?
I asked about that recently when thinking about doing this. Cranky and shady lane said input side, still_stirrin said output side. I am going to try this on the input side for the reason you mention, hot water. They’re polypropylene which melts much higher than boiling. These John Guest fittings and tubing do have pressure ratings at elevated temps, but on the output side they won’t be under pressure if I have the valve on input. Different story on output if this doesn’t work out.
