Plumbing, explained before it’s fixed.

Northline Plumbing & Drain handles leaks, blocked drains, water heaters and fixtures for homes, rentals and commercial properties. You get the problem, the plan and the scope in plain language before work starts.

Common problems, in plain terms

Five symptoms, what usually sits behind each, and what we check first.

A drain that keeps slowing down

Likely cause

Buildup further along the line than the visible trap.

What we do

Clear the line, then check whether something is causing it to return.

Water stains on a ceiling or wall

Likely cause

A slow leak behind the surface, often at a joint or fixture.

What we do

Locate the source first, then open only what we need to.

No hot water, or it runs out fast

Likely cause

A failing heating element, thermostat or sediment buildup.

What we do

Diagnose the unit, then repair or replace based on its condition.

Low pressure at one fixture

Likely cause

A clogged aerator, a partly closed valve or a worn cartridge.

What we do

Check the fixture and its supply before looking further upstream.

A faucet or toilet that won’t stop running

Likely cause

A worn washer, seal or flapper.

What we do

Replace the worn part and test for leaks.
