Why is my water pressure low?
Two things usually cause low water pressure in an apartment. Sediment collects in your faucet aerators and chokes flow at one fixture. Calcified galvanized pipes and a failing pressure-reducing valve (PRV) drop pressure across the whole building.
Struggling to rinse the shampoo out of your hair because of a weak, trickling showerhead? Dealing with low water pressure in Brooklyn is a real nuisance. Older brownstones and pre-war buildings carry aging supply piping, and it shows up at the fixture.
Steer clear of major DIY fixes. Leave the pipes under your sink alone. A few simple checks narrow the problem down first. Then bring in a licensed plumber to fix a low water pressure apartment issue safely.
DIY Checks: Where to Look When Your Pressure Drops
If your water pressure suddenly dips, here is how you can investigate the root cause without picking up a wrench:
- Check Multiple Fixtures: Turn on the sinks and showers in your bathroom, and then check your kitchen. Low pressure at a single faucet narrows it to that fixture. Look first at the aerator, the small mesh screen at the tip of that faucet. Scale and sediment collect there.
- Compare Hot vs. Cold Water: Turn on only the cold water, and then only the hot water. Strong cold water with a weak hot trickle points away from the main water line. The cause usually sits inside your water heater or boiler: sediment buildup, or a failing valve.
- Ask Your Neighbors: In a multi-family building, ask the tenant next door whether their pressure dropped too. Low pressure building-wide points somewhere else: the city water main, or the building’s main pressure-reducing valve (PRV).
- Look for Hidden Leaks: Sometimes a severe drop in water pressure means the water is escaping somewhere else. Check the walls and ceilings below your bathroom for water stains, and listen for the sound of a running toilet.
When to Call an NYC Plumber for Low Water Pressure
Clean aerators and still-weak pressure usually means structural pipe calcification. Over decades, older galvanized steel pipes corrode and calcify from the inside out, choking the water supply. Replacing sections of calcified piping or repairing a building’s main PRV requires advanced diagnostic tools and a licensed professional.
