Nationwide Plumbers is a NYC Licensed Master Plumber, License #2023, in business since 1984 with 24/7 emergency dispatch. In Mariners Harbor we install sump pumps and backwater valves, repair sewers, replace water heaters and serve commercial and industrial properties. Call 718-748-2727.
Mariners Harbor sits at the northwest corner of Staten Island along the Kill Van Kull, with Richmond Terrace running beside the water and Forest Avenue farther inland. The name goes back to the oyster captains and sailors who settled here, and a few of their 19th century houses still stand along Richmond Terrace. Most of today's housing is newer: attached townhouses and two-family homes built over recent decades, alongside apartment complexes and working industrial and maritime sites on the waterfront.
Low ground near the Kill and a large stock of townhouses define the plumbing calls here. Basements and ground floors close to the water can take on water in storms, and townhouses built in the same years tend to need water heaters, fixtures and drain repairs at the same time. Commercial and industrial properties along the Terrace need backflow testing and heavy-duty drain service. Mariners Harbor is covered by our 24/7 dispatch.

Common plumbing issues in Mariners Harbor
Storm water on low ground
Blocks near Richmond Terrace and the Kill Van Kull sit low, and heavy rain or storm tides can push water into basements and garages. Some comes through the foundation, and some comes up through floor drains from the sewer. A sump pump with backup power handles the first, and a backwater valve on the house sewer handles the second. We check how water is entering before recommending either.
Townhouses aging at the same time
When a row of townhouses is built together, the water heaters, toilets and faucets wear out together too. Owners often call after a neighbor's tank fails and wonder if theirs is next. We inspect the water heater, expansion tank and shutoff valves, replace what is near the end, and can install a wall-hung tankless unit where the gas line and venting allow.
Commercial and industrial drains
Yards, warehouses and shops along the waterfront send dirt, grit and oil into drains that see heavy use. Sediment settles in the lines and causes backups. Most of these properties also need a backflow preventer tested yearly. We clear and jet lines, camera them for damage, and handle backflow testing and filing so the property stays in compliance.

Plumbing in Mariners Harbor: FAQ
Do I need both a sump pump and a backwater valve?
Not always. A sump pump removes groundwater that seeps in, while a backwater valve stops sewer water from coming up through drains. Homes on the lowest blocks near the Kill often benefit from both. We inspect first and give a free estimate on the installation.
Who supplies gas in Mariners Harbor?
National Grid supplies gas on Staten Island. If you smell gas, leave and call National Grid or 911. Afterward, we can find and repair the leak, pressure test the piping and help with gas restoration if service was shut off.
Can you test backflow at an industrial site?
Yes. We test backflow preventers at commercial and industrial properties, repair or replace failing devices and file the results with the city. Industrial yards often have larger devices, and we bring the right test kit for them. Call 718-748-2727 to schedule the yearly test.
