Poway disposals mostly fail from jams, tripped overloads, worn gaskets and scale, and the city water is hard enough to speed that wear. A plumber can sort out whether the unit, the trap or the drain behind it is at fault. Call the number on this page to be connected with a local plumber in Poway.

How hard is Poway water on a disposal?
Harder than many homeowners expect. The City of Poway treats its own water at the Lester J. Berglund Water Treatment Plant and reports hardness of roughly 228 to 235 ppm as calcium carbonate, with a range of 165 to 291. That mineral load leaves a pale crust on the sink flange and inside the dishwasher inlet, and gaskets hardened by scale are a common reason a disposal starts dripping at the top or side. The City disinfects with both chlorine and chloramines, and rubber splash guards tend to wear out before the motor does.
Is my 1970s kitchen drain part of the trouble?
It might be. The median Poway home was built around 1978, so many kitchens have a trap arm and branch line that have carried food waste for decades. If the sink stays slow after a jam is cleared, or a new unit drains no better than the old one, the clog is probably in the pipe beyond the disposal. A plumber can clear that line rather than sell you a unit you do not need.
Water and sewer both come from the City and show up on one City of Poway Water / Sewer account. For account questions, Customer Services is at 858-668-4401.
What does a Poway permit have to do with it?
For a straight swap on the existing trap, usually very little. Larger kitchen plumbing changes are another matter. The City of Poway Building Division takes electronic submittals only, through City of Poway Online Services, with plan check and inspection handled for the City by EsGil Corporation. Building Services is at 858-668-4645. If your disposal job turns into new drain piping or a relocated sink, the plumber can tell you whether a permit applies.
A short local note
Some Poway homes have a second disposal in a bar sink or patio kitchen. Units that sit unused for weeks can seize; running them briefly with cold water every so often keeps the turntable free. If an outdoor unit has quit, mention it when you call so the plumber brings the right parts. A unit that hums, trips or leaks from its base should be turned off until it is looked at.
