In South San Francisco, 81% of the housing was built before 1990. About 61% of households own their home and 39% rent, so this page has two readers.

Short version

61% of occupied homes in South San Francisco are owner-occupied and 39% 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 is 81% pre-1990, which dates the house rather than the fixture.

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 is actually wrong with it

Which of these is it? Running continuously, not flushing at all, flushing weakly, leaking at the floor, or moving when you sit on it. Each has a different cause and only one of them is urgent.

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.
