Toilet Repair in Mercer Island, WA

Mercer Island is mixed on both counts: 72% of its housing predates 1990, and 66% of households own rather than rent.

Short version

66% of occupied homes in Mercer Island are owner-occupied and 34% are rented, which is close enough to even that the first question is which you are. A landlord is generally responsible for a fixture in a tenancy; an owner is not. Housing there splits either side of 1990 at 72% pre-1990, so flush volume is worth checking rather than assuming.

Tank and Bowl is a referral service, not a contractor. We connect homeowners with independent contractors. Contractors are required to hold whatever credential their state or municipality demands. Every state page sets out who licenses plumbers there and where to check, so you can confirm before work begins. We carry out no work, we sell no fixtures, we do not set prices, and we never charge homeowners anything — the contractors in our network pay us when we route them a call.

What the age of Mercer Island’s housing suggests

Mercer Island straddles the line: 72% of its housing units were built before 1990, when the Energy Policy Act of 1992 set the 1.6 gallon maximum, and the rest since.

So the housing stock genuinely does not predict the fixture here, and the date inside the tank lid is worth more than any figure on this page.

What is actually wrong with it

Work from the symptom rather than the fixture. Continuous running has a ten-minute test that settles it; water at the base is identified by when it appears rather than where; and a handle that does nothing is visible the moment the tank lid is off.

Ask what happens to the floor. A leak at the base has usually been going for a while by the time it is visible, and whether the subfloor and flange are sound is the difference between a seal replacement and a return visit.
