Plumbing Advice for New Homeowners

Buying a home in Bridgewater or anywhere in Central New Jersey means inheriting a plumbing system you didn't choose — pipes, a water heater, drains, and a sewer line with a history you can only partly see. The first few weeks in a new house are the best time to learn a few basics, because the things new owners usually discover during an emergency are much cheaper to learn on a quiet afternoon. Here is what to find, check, and keep an eye on first.

Find Your Main Water Shutoff — Before You Need It

This is the single most useful thing to learn about a new house. The main water shutoff stops water to the whole home, and it is usually near where the water line enters the house — often in the basement, near the front wall, or by the water meter. Find it, make sure you can turn it, and show everyone in the household where it is. If it is seized up or drips when you turn it, have it looked at before you need it in a hurry. The same goes for the smaller shutoff valves under each sink and behind each toilet: they let you stop water to one fixture without shutting down the house, but only if they still turn. A valve that won't move is a repair waiting for the worst moment — see our article on what happens when plumbing repairs wait.

Learn Your Water Heater

Find out where the water heater is, whether it is a tank or a tankless unit, and how old it is — the information is usually on a label on the unit itself, or in the paperwork from the sale. Then look at it: rust or water pooling at the base, rumbling during heating, and hot water that runs out faster than it used to are all signs a tank is wearing out, and a leaking water heater is a prompt call, not a watch-and-wait item. If the house has a tankless unit, it needs its own kind of attention — regular service keeps it running efficiently. See our water heater repair & installation page, including tankless options.

Get to Know Your Drains and Sewer Line

Every drain in a new house has a past. Run the taps and watch how fast each drain clears, and flush each toilet to see that it fills and empties properly. A drain that is slow from day one has a partial blockage — grease, buildup, or roots narrowing the line — and slow drains only get slower. Only water, toilet paper, and what the toilet is made for should go down a toilet: wipes, even ones labeled flushable, and grease poured down a kitchen sink are two of the most common causes of clogs we see. Find out where the sewer cleanout is, too — it is the access point a plumber uses to clear or camera the sewer line, and knowing where it is saves time when a line backs up. If drains are slow in several places at once, or the same line keeps clogging, the line itself may be the problem; a sewer camera inspection shows exactly what is going on underground. See our drain cleaning and sewer services pages — drain cleaning can be booked online for $99.

Look for Leaks in the First Weeks

Walk the house with fresh eyes in the first month: look under every sink and around the base of every toilet for dampness, stains, or swelling; check the ceilings under upstairs bathrooms; look at the walls behind the washing machine hookup. A small leak you can see is only part of the story — water soaks into cabinet floors, subfloors, and drywall quietly, often for weeks before it shows as a stain. Your water bill is the other early warning: if it climbs for no clear reason, a hidden leak is one of the first things to check. See our article on why a water bill goes high for how hidden leaks show up, and our plumbing services for leak detection and repair.

Older Home? A Few Extra Checks

Much of Central New Jersey's housing stock is older, and older homes carry older plumbing. Low water pressure throughout the house, leaks appearing in several places, pipes that look corroded, and clogs that keep returning in the same line all point to pipework wearing out rather than a single fixture failing. If the inspection report mentioned galvanized or aging supply lines, or a sewer line with root intrusion, don't file that away — get a plumber's read on it early, while it is a planned job instead of an emergency. Our article on plumbing repair issues in older homes covers the patterns to watch for.

Your First Winter in the House

New Jersey winters are hard on plumbing, and your first winter in a new house is when you find out where the cold spots are. Pipes in unheated spaces — basements, crawl spaces, garages, and exterior walls — are the ones that freeze, and a frozen pipe can burst. Before the cold sets in, disconnect garden hoses, shut off and drain outdoor hose bibs if the house has a shutoff for them, and make sure pipes in cold spots are insulated. Keep the heat on even when you are away, and know where the main shutoff is — if a pipe does freeze and burst, stopping the water fast is what limits the damage. If a faucet gives you little or no water on a freezing morning, or you find a burst pipe, shut off the water and call right away.

Know What You Shouldn't DIY

Some homeowner jobs are fine — plunging a slow toilet, cleaning a faucet aerator, replacing a shower head. But a leak you can't stop, a sewer backup, a water heater leaking at the base, or a burst pipe are jobs for a licensed plumber, and trying to force them can make the damage worse. And if you smell gas near a gas appliance or line, leave the house and call your gas utility or emergency services first — that is not a plumbing call to wait on.
