Answer these two lists honestly before you call. Triage sorts urgency; it does not diagnose your pipes from a web page.

Between the two lists? Describe the symptoms when you request help. Homes near the Schuylkill should also watch basements after heavy rain. In rowhomes and twins, tell neighbors below or beside you if water may be traveling. Not sure? See what counts as a plumbing emergency.

Northwest Philadelphia is not one housing type. Stone Victorians on the Hill, mill-era rowhomes on Manayunk’s slopes, and twins and rowhomes in Germantown and East Falls each push plumbing toward different failures. Match what you see to the pattern below.

Pick the problem that matches what you see. Each page covers safe first steps, warning signs, and what a plumber may do.

A pipe burst after a freeze. I have an oil heat system that feeds radiators throughout the house. Should I turn off the oil boiler until morning?

Shut the water off first, since that stops the damage. If the system lost water, switching the boiler off keeps it from firing dry, then request help. Do not drain the radiators yourself unless a professional tells you to.

What happens when a radiator bursts because the pipes froze? Tiny holes started forming, one after another, along a single vertical tube.

Freezing water expands and splits the metal, and pinholes often open in a row along the weakest tube. A plumber checks whether that radiator can be isolated and whether the rest of the loop survived. In the radiator-heated homes common across Germantown and Mt. Airy, the full loop needs checking before the heat goes back on.

We bought a 1928 house and found tree roots blocking up to 75% of the sewer line. One company quoted $7-8k for pipe bursting, and another suggested cutting the roots and lining the pipe. Which is right?

Both are legitimate repairs, and the right one depends on the pipe’s condition, depth, and access. Bursting replaces the line while lining preserves it after the roots are cut out. Get a camera inspection and written quotes for both options before you decide.

I got quotes between $3k and $10k for tree root damage on a deep sewer line. Should I fix the existing pipe or cut a new trench with easy access to the mains?

Depth drives the price because excavation is the expensive part, so access is the real question. When the old pipe’s route is sound, repairing in place usually costs less than a new trench. In Philadelphia you own the lateral from your home to the main, so confirm where that responsibility ends before anyone digs.

We have a toilet in the basement. When we do laundry, shower, or use the upstairs toilets, drainage comes up and overflows the basement toilet. What should we do?

That pattern points to a main line blockage: wastewater has nowhere to go except the lowest fixture. Stop using water in the house and request help, since more flushing makes it worse. Skip chemical drain cleaners for a suspected main line clog.

The toilet keeps backing up and overflowing. When I plunge it, water comes up in the bathtub, and all the drains run slowly.

Water moving between fixtures means the blockage sits past the branch lines, in the main drain or the lateral. Stop running water and request help; this is past what a plunger can fix. Keep people and pets away from any water that came up through a drain.

Why does my basement flood during long rains? The sump pump ran for 30 hours straight, which is longer than usual.

A pump that never stops is either overwhelmed by inflow or starting to fail: check the power, the float switch, and that the discharge line is clear and sends water away from the house. When the pump checks out and water still comes in, inflow exceeds capacity and the setup needs an upgrade or a backup pump. Long-rain flooding matches the pattern Philadelphia’s emergency office warns about for river-adjacent and low-lying blocks.

A friend in a Philadelphia row home has a flooded basement. How should he handle the mold and mildew risk?

Stop the water source first, then dry the basement fast: pump or wet-vac standing water, ventilate, and pull out soaked porous materials like carpet and cardboard. Watch walls and stored items over the next few days, and remove anything that stays damp. A plumber fixes the entry point so the next storm does not repeat it.

What are the main causes of low water pressure, and is there a way to improve it?

In older homes the usual causes are mineral buildup and corrosion inside aging supply lines, a failing pressure regulator, or a valve that is only partly open. A plumber measures pressure at several points to find whether the restriction is inside the home or on the supply side. Repiping is the last resort, not the first guess.

Water is slowly seeping from the bottom of our water heater and it looks rusty. Is the unit done for?

Rust-colored seepage from the tank bottom usually means the tank itself is failing, and tanks cannot be repaired. Shut off the water and the power or gas to the unit, contain the leak, and plan for a replacement. Have a plumber confirm the source on inspection before you buy anything.
