Just installed Hayward 250,000 BTU natural gas heater and it says to install a flow meter to make sure you are getting the proper water flow through the heater. Where can I find one that does not cost an arm and leg. Also does it install between the filter and the heater inlet port or does it install between the heater return line and the chlorinator?
Any help would be greatly appreciated.
Thanks
