Pool Heater By-Pass?

[Gary R]

Hi to all;

Pool heater has by-pass installed, just wondering if there is any reason to keep it in the loop when not in use for the rest of the summer. Should I drain and blow out excess water.

Thanks,

Gary R. :-D

Bypassing the heater when you won't be using it for a while is easy and well worth. Draining the heater until fall is more work and makes less difference. There is no harm in it, but I doubt it will make a detectable difference.
