Evaporator and furnace condensate drain, pH neutralizer needed?
Hello! I have a Bryant 915SA high-efficiency furnace with a Bryant CNPHP AC evaporator unit. Both the AC evaporator and furnace condensate drains were going into a single PVC pipe, then into a 'pH Treat' acid neutralizer, then into the sewage line.
The pH neutralizer is vertical-mount only, and was wrongly installed horizontally. It thus clogged up, backed water into the furnace and evaporator, and generally flooded the attic. As a temporary solution I removed it entirely and bypassed it with a flex tube, so now both the furnace and evaporator drain directly into the sewage (each still having a trap).
- Does this setup even need a pH neutralizer for the furnace? I can't find any reference to this requirement in the installation manual and my city's sewage code.
- Shouldn't the AC evaporator drain bypass any pH neutralizer anyway?
- While on this topic, why doesn't my high-efficiency tankless gas water heater have a neutralizer for its condensate line?
Thanks for reading, and appreciate any thoughts you may have!
