Toilet Repair in Portsmouth, NH

Two figures shape this page. 81% of housing in Portsmouth was built before 1990, and 47% of households rent rather than own.

Short version

Renting is the majority position in Portsmouth, at 47% of occupied homes. A fixture in a tenancy is generally the landlord's responsibility to repair, which makes the lease the first document to look at and not the last. With 81% of the housing built before 1990, a fixture predating the 1.6 gallon standard may still be in place; the figure describes the building rather than the bathroom.

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 Portsmouth’s housing suggests

Housing in Portsmouth is mostly older than the standard: 81% of it went up before 1990. A toilet fitted when those homes were built used at least twice what a current one does.

Whether the original is still there is a different question, and the only way to settle it is to look at the fixture.

What is actually wrong with it

Most calls are one of five things, and the useful first step is deciding which. Three of them — running, a weak flush and no flush at all — live inside the tank. The other two, a leak at the base and a rocking fixture, are underneath it and are related to each other.

Two questions are worth asking whoever comes: which part they tested before reaching a conclusion, and whether anything under the fixture needs attention. The second one is what separates a repair that lasts from one that repeats.
