Clogged Drains near you

Kitchen lines fail from the inside out. New York City's Department of Environmental Protection describes grease poured down a kitchen sink as clinging to the inside of household plumbing and the pipes of the sewer system, and warns that when wastewater cannot move freely because of a blockage, it can cause flooding and a sewer backup into the home. The city's advice is to let cooking oil and grease cool, put it in a container or a sealed bag, and throw it out rather than rinsing it away with hot water, which only moves the problem downstream to where the pipe is colder.

Bathroom lines fail differently. Wipes are the recurring offender, including the ones sold as flushable, because they do not break down the way toilet paper does; combined with grease they form the mats that plug laterals and municipal mains alike. Further out, tree roots find their way in through cracked joints and defects, thicken season by season, and catch everything that passes. A house with mature trees over the line and original clay or cast iron pipe is the classic recurring-blockage candidate, and no amount of careful flushing will change that until the pipe is repaired.

Work usually moves from the fixture outward. A plumber will pull and clean a trap or use a small drum machine on a branch line first, since that solves most single-fixture complaints. For a building drain or a lateral, the cable goes in through a cleanout — the capped access fitting inside the house, at the foundation wall or in the yard — using a larger machine and a cutting head sized to the pipe. Where the line is greased over rather than obstructed by one object, high-pressure water jetting scours the pipe wall instead of punching a hole through the blockage, which is why a jetted line tends to stay clear longer.

A camera inspection is what turns a repeat clog into a diagnosis. The City of Minneapolis tells homeowners plainly that it does not televise private laterals to find blockages and that a homeowner can hire a company to do it, and the same holds in most cities. The video shows whether you are looking at roots at a joint, a belly holding water, an offset or a crushed section, and a locator on the camera head marks the spot and depth in the yard so a repair does not become exploratory digging.

Ask for the footage, or at least for a look at the screen while the head is in the pipe. A recording made before and after cleaning is the most useful record you can keep, and it is the thing to hand the next plumber, an insurer or a buyer's inspector rather than trying to describe the problem from memory.

Sewage in the house is not merely unpleasant. EPA describes sewage as containing bacteria, viruses, protozoa, helminths and inhaled molds and fungi, with illnesses ranging from mild gastroenteritis to life-threatening conditions such as cholera and dysentery. That is the reason to stop using water in the house the moment a backup starts, to keep children and pets out of the affected area, and to wear gloves and eye protection if you have to move anything out of the water.

Caustic drain cleaners deserve their own caution, particularly when a drain is already standing full. CDC's Agency for Toxic Substances and Disease Registry notes that sodium hydroxide is commonly present in commercial drain and oven cleaners, that direct contact with the solid or concentrated solutions causes thermal and chemical burns leading to deep-tissue injuries, that strong solutions can cause severe eye damage, and that dissolving it in water liberates substantial heat. Poured into a blocked line, the product sits in the pipe, and it is then waiting for the plumber who opens the trap. Tell whoever you call what you have already put down the drain.

There is no national plumbing licence in the United States, so what qualifies the person at your door depends on the state. Washington's Department of Labor and Industries requires certification by the state Plumber Certification Program to work in the plumbing trade, with a journey level certificate covering all phases of plumbing construction and narrower certificates such as residential and residential service covering defined work in houses and duplexes. Minnesota's Department of Labor and Industry licenses master and journeyworker plumbers, licenses the plumbing contractor as a business that must keep a licensed master plumber as its responsible individual, and issues restricted licences limited to municipalities under five thousand people. California licenses the contractor rather than the individual tradesperson, through the Contractors State License Board's C-36 Plumbing classification, whose scope expressly covers complete removal of waste from the premises.

Simple clearing of a fixture drain rarely involves a permit. Replacing or repairing pipe usually does: Minneapolis, for example, states that a permit is required to repair a sanitary lateral so the work is done properly and meets city code. Permits and inspections are administered by your city or county building department, not by the state, so ask who is pulling the permit and who will meet the inspector before repair work starts.
