Port Morris is the industrial southeast corner of Mott Haven, running along the East River and the Bronx Kill toward Randall's Island, with Bruckner Boulevard and the Bruckner Expressway crossing the top. For most of its history it was warehouses, factories and rail yards, and much of that remains: distribution buildings, food businesses, auto shops and storage. Older brick industrial buildings have been converted to studios, offices, restaurants and lofts.

Residential pockets of 19th century rowhouses survive here and there, and new apartment buildings have gone up near the water in recent years. That makes Port Morris a mostly commercial service area. The work centers on backflow testing, large drain lines, grease from food businesses, and older industrial piping that was never meant for apartments or restaurants. Con Edison supplies gas here.

Common plumbing issues in Port Morris
Backflow devices on industrial water services
Warehouses, food processors and businesses with boilers, fire lines or process water usually need a backflow preventer, and every device must be tested each year with results filed with the city. Failed tests and missed filings bring violations. We test, rebuild or replace failed assemblies, and handle the paperwork. Multi-tenant buildings with several devices can be scheduled in one visit.
Old industrial piping in converted buildings
When a factory or warehouse becomes offices, studios or a restaurant, the original water service, drain lines and gas piping were sized for a different use. The result can be low pressure, slow drains or a gas supply that cannot carry new kitchen equipment. We evaluate what is there, size upgrades to the new use and handle the plumbing side of the conversion.
Grease and solids in commercial lines
Food businesses and distributors send grease, food waste and solids into drain lines that may already be decades old. Lines clog, interceptors back up and smells travel. We clear lines with our van-mounted jetter, camera them to check for damage, and set up a cleaning schedule. See hydro jetting for details.

Plumbing in Port Morris: FAQ
Our backflow test failed. What happens next?
The device needs to be repaired or replaced and then retested, and the passing result filed with the city. Many failures are fixed by rebuilding the internal parts. If the assembly is too old or damaged, we replace it. We handle the full process and the filing.
Can you upgrade plumbing for a loft or restaurant conversion?
Yes. We evaluate the existing water service, drains and gas piping, then design and install what the new use needs. Work like this usually requires filings with the Department of Buildings, and we tell you what is needed before work starts. Estimates are free.
Do you service warehouses outside business hours?
Yes. We dispatch 24/7 for emergencies, and planned work like jetting or backflow testing can be scheduled early in the morning or in the evening so it does not interfere with deliveries.
