I came to give an estimate for a rear outlet toilet and check their filter. I took a field test for the raw and treated water Treated- PH:7 H:2 FE:0 Raw- PH:7.5 H:17 FE:Trace I removed the sediment filter and replaced it with a customer supplied sediment filter and cleaned and lubricated the o ring. I removed the injector and screen for the softener. The injector was plugged with sediment. I adjusted the time and reinstalled the injector after cleaning it.
