Read →Polybutylene pipe replacement: how to identify it, the lawsuit, and what replaces it
Polybutylene is gray or blue plastic pipe installed about 1978 to 1995, stamped "PB2110." Chlorine degrades it from the inside and its fittings crack, so insurers and inspectors treat it as a full repipe. The lawsuit claim window has closed.

Bellevue homes built between 1978 and 1995 on concrete slab foundations used copper supply lines embedded in the slab. Those pipes are now 30–50 years old and failing on a predictable schedule in specific neighborhoods. Here is why, where, and what to do.

Read →Sewer line cleaning in Bellevue: when to do it, what it costs, and what method is right
Most Bellevue homeowners should have their sewer lateral cleaned every 18–36 months if they have mature trees nearby, or every 5–7 years otherwise. Hydro-jetting clears the full pipe diameter; cabling clears soft blockages faster and cheaper. Here is how to choose.

Bellevue's soft water consumes magnesium anode rods faster than hard-water markets, leaving tanks unprotected by year 5-7. The $200-$500 replacement extends water heater life by 4-7 years — payback math that strongly favors doing it.
Read →Water heater leaking from the bottom: causes, diagnosis, and when to replace
A bottom leak is usually a failing drain valve, T&P discharge, or condensation — all repairable. Water pooling under the tank means the steel has corroded through and the unit must be replaced.
Read →Water heater not heating: electric and gas causes, tests, and fixes
On electric units, no heat is most often a tripped reset or a failed element or thermostat. On gas units it is an out pilot, a weak thermocouple, or a failed gas valve — diagnosed in that order.

Classify the symptom first — none at all, runs out fast, lukewarm, or hot-then-cold — then split gas from electric. Each pattern points to a different cause, from a tripped reset to a broken dip tube.

Popping and rumbling almost always mean sediment trapping steam at the tank bottom — flush the tank and check the anode rod. Ticking is thermal expansion; a screech is a restricted valve.

Garbage disposal not working: a dead-vs-jammed diagnosis and the four-step fix
