I am in process of installing new SWG. If I install after the filter and before the heater it will be a 30 minute job. The piping that comes out of the heater only runs about 6 inches before hitting valves and will take major planning and work to re-plumb to accept SWG.
What will happen if I put this in before the heater? Living in Houston I only use the heater for maybe 10 hours a year.
I appreciate any advise.
