Toilet Repair in Union City, CA

Neither figure in Union City points one way. 70% of the housing was built before 1990 and 33% of households are renting.

Short version

67% of occupied homes in Union City are owner-occupied and 33% 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 70% 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 Union City’s housing suggests

About 70% of homes in Union City predate 1990. That is close enough to even that the town average tells you very little about any one house, which is worth saying rather than dressing up.

What it does tell you is that both generations of fixture are common here, and they fail in different ways.

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.

If you are quoted for a new fixture, ask what ruled out the parts. Flappers and fill valves are inexpensive and account for most of what goes wrong, so replacing the toilet without testing them has skipped a step.
