Toilet repair. Replaced gasket/flapper on Kohler toilet on 1st floor powder room toilet Pool heater repair. Cleaned the pool heater and tried to get the pool heater to burn properly. Flames were coming out of the right side of the heater when I arrived. I cleaned and blew out the system as good as I could, and it burned cleaner without flames coming out, but not 100% blue flames. It had flickers of orange, but was not erratically flaming.
