Norwich, renamed for the mail.
Wikipedia says the hamlet was simply Norwich until the postal service asked for a new name to avoid confusion with Norwich in Chenango County. It sits on the Harbor Hill Moraine, is served entirely by the Oyster Bay–East Norwich school and library districts, and has no train station; the nearest are Oyster Bay and Syosset. The CDP covers 1.0 square mile, all land.
The Census Bureau's latest five-year survey counts about 1,000 homes, with a median year built of 1958. 44% went up in the 1950s, 16% before 1940, and 10% after 1980. 97% are single-family detached houses, and 98% are owner-occupied.
So a typical house here has drain and water lines around 68 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 31% 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.
Water heaters in East Norwich.
The Census Bureau's survey puts the average owner household at 2.90 people, with a median of 7.6 rooms; 97% of homes have three or more bedrooms and 61% have four or more. A tank sized for a smaller household, or one full of sediment, is what runs out first when several people shower back to back. When a heater fails, we size the replacement to the household and the number of bathrooms, not just to the label on the old tank. With this much oil heat, many houses make hot water from the boiler (a coil or an indirect tank), so an oil-to-gas switch usually means a new water heater and gas piping too; we do both.
Cesspools and septic, mostly.
Nassau County's health department list of sewer collection districts shows East Norwich as not publicly sewered, and Wikipedia says most of the hamlet relies on cesspools and septic systems, with a portion inside the Oyster Bay Sewer District. A sewer district charge on your tax bill means you're connected. We clear the line from the house, but a full or failing cesspool is a job for a cesspool or septic contractor; we don't do cesspool work, and we don't install septic systems.
Little mapped flood risk.
FEMA's current flood map puts none of East Norwich in the high-risk flood zone.
Water: Jericho Water District.
EPA's service-area map puts about 78% of residents on the Jericho Water District, with about 22% on the Oyster Bay 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 reported no PFOA or PFOS. 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.
East Norwich is an unincorporated hamlet, so plumbing permits go through the Town of Oyster Bay Department of Planning and Development.
Local reference points: the Route 25A and Route 106 crossroads, Highwood Road and Sugar Toms Lane.

Questions
East Norwich plumbing FAQ
Do you cover all of East Norwich?
Yes, all of East Norwich (ZIP 11732, 11771), plus the neighboring communities listed below.
Is East Norwich on a sewer or a cesspool?
Most homes here use a cesspool or septic system; a sewer district charge on your tax bill means you're connected. We clear the house drain line, but cesspool pumping or replacement is for a cesspool or septic contractor.
Who supplies my water?
EPA's service-area map puts about 78% of residents on the Jericho Water District, with about 22% on the Oyster Bay Water District. Your bill says which. For leaks at the curb or meter, call the supplier; inside the house, call us.
What size water heater does a East Norwich house need?
It depends on the people and bathrooms, not the house's age. East Norwich's average owner household is 2.90 people and 97% of homes have three or more bedrooms, so we size the tank to your household and fixtures, and check the gas line or wiring, flue and relief valve when we install it.
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 East Norwich?
We answer calls 24/7. We're open Monday through Saturday and closed on Sunday. Call (631) 644-2084.
