North Hempstead's youngest village.

Wikipedia says residents voted unanimously to incorporate on May 16, 1932, after neighboring Manorhaven tried to annex the area in 1931; it's still the youngest village in the Town of North Hempstead. Shore Road was rebuilt and widened through the village in the 1940s. Today it mixes homes with waterfront, shopping (Soundview Marketplace) and light industry, including Grumman Studios on the former Publishers Clearing House headquarters site. It covers 0.5 square miles, about 4% water.

The Census Bureau's latest five-year survey counts about 1,500 homes, with a median year built of 1969. 5% went up in the 1950s, 4% before 1940, and 23% after 1980. 59% are single-family detached houses, 20% are in buildings of five or more units, and 66% are owner-occupied.

So a typical house here has drain and water lines around 57 years old unless they've been replaced. Slow drains in several fixtures, a gurgling floor drain or rusty water from one tap are signs to have the main line and supply piping checked.

Oil to gas means new gas piping.

The ACS shows 67% of homes heat with utility gas and 19% with fuel oil. Switching means properly sized gas piping to the new equipment, and often to the water heater, range and dryer. We do the gas line work. We don't sell or deliver oil.

On the sewer.

Port Washington North isn't listed separately in Nassau County's health department sewer list; Wikipedia says the village is inside the Port Washington Water Pollution Control District, which the county list shows at 70 Harbor Rd. (516-944-6100). A backup that stops at your house is usually in your own line to the street; we clear it and repair or replace the line. If neighbors are backed up too, call the Port Washington Water Pollution Control District (516-944-6100).

Flood risk.

Laying FEMA's current flood map over the Census boundary, about 9% of Port Washington North is in the high-risk (1% annual chance) flood zone (5.8% in zone AE, 3.5% in zone VE; shares of the Census area, water included). On a sewered street, a backwater (sewer check) valve on your house sewer line can keep a street-sewer backup from coming in through basement floor drains. We install them. If your water heater or gas appliances ever sat in flood water, have them checked before relighting.

Water: Port Washington Water District.

EPA's service-area map puts essentially all residents on the Port Washington Water District; your bill is the final word. The main supplier's most recent 90th-percentile lead result was 2 ppb, under the 15 ppb action level; lead usually comes from a home's own pipes and fixtures, so results vary house to house. In EPA's UCMR 5 testing, the main supplier's highest single PFOA/PFOS result was 5.3 parts per trillion. EPA's 4 ppt limits apply as a running annual average starting in 2029, so one high sample is not a violation, but it's the kind of number a carbon filter is sized against. For a leak at the curb or in the street, call your water supplier. For anything on your side of the meter, call us.

Permits.

Port Washington North is an incorporated village, so plumbing permits go through the Village of Port Washington North's building department, not the town.

Questions

Port Washington North plumbing FAQ

Do you cover all of Port Washington North?
Yes, all of Port Washington North (ZIP 11050), plus the neighboring communities listed below.
Sewage came up through my basement floor drain. Who do I call?
If it's only your house, the blockage is usually in your line to the street: call us. If neighbors have it too, the public sewer may be backed up: call the Port Washington Water Pollution Control District (516-944-6100).
Can a backwater valve keep sewage out of my basement?
That's what it's for. A backwater (sewer check) valve goes on your house sewer line and closes when the street sewer backs up, so sewage can't flow back in through floor drains and low fixtures. It has to be kept clear and checked from time to time to keep working. We install them. Call (631) 644-2084.
Is my house in the flood zone?
About 9% of Port Washington North is in FEMA's high-risk zone. FEMA's Flood Map Service Center will show your exact address.
Who supplies my water?
EPA's service-area map puts essentially all residents on the Port Washington Water District. Your bill says which. For leaks at the curb or meter, call the supplier; inside the house, call us.
Can you handle the gas piping when I switch from oil to gas?
Yes, we install and repair gas lines for heating equipment and appliances.
When can I reach you in Port Washington North?
