Constant Drain Leaks? Check Your Seal Stack Assembly! 🚰
If your iron filter or water softener is constantly dripping or running down the drain, a fouled seal stack is usually the prime suspect.
As shown in these photos, heavy iron accumulation blocks the valve’s internal seals, preventing the system from sealing off after a backwash cycle. Typically, when a stack gets this severely fouled, the filtration media inside the tank is heavily loaded with iron as well.
For homes with iron in their well water, we strongly recommend an annual Water Man house call. Regular checkups keep your control valves clean, protect your filtration media, and prevent unexpected water waste.
