Wolver Hollow, Tappentown, then Brookville.
Wikipedia says the area was known as Suco's Wigwam when the Town of Oyster Bay bought it from the Matinecock, Dutch settlers called it Wolver Hollow, and for most of the 19th century it was Tappentown, after a prominent family; Brookville took over after the Civil War. By the mid-1920s there were 22 estates here, and the estate owners incorporated the village in 1931. The Post estate, Hillwood, became Long Island University's C.W. Post campus in 1947, home of the Tilles Center. In the 1950s the village annexed the northern part of Wheatley Hills, roughly doubling it to 2,650 acres (4.0 square miles).
The Census Bureau's latest five-year survey counts about 900 homes, with a median year built of 1967. 26% went up in the 1950s, 10% before 1940, and 43% after 1980. 96% are single-family detached houses, and 93% are owner-occupied.
So a typical house here has drain and water lines around 59 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 44% of homes heat with utility gas and 43% 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 Brookville.
The Census Bureau's survey puts the average owner household at 2.44 people; 96% of homes have three or more bedrooms and 82% 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 Brookville as not publicly sewered, so expect a cesspool or septic system. 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 Brookville in the high-risk flood zone.
Big houses, long runs.
The Census survey counts 82% of Brookville's homes with four or more bedrooms and 43% still heating with fuel oil. Big houses on big lots mean long water and drain runs, and often a long line out to the cesspool or septic system, so a slow drain can be well outside the house. We find which run it is before we open anything.
Water: Jericho Water District.
EPA's service-area map puts essentially all residents on the Jericho 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.
Brookville is an incorporated village, so plumbing permits go through the Village of Brookville's building department, not the town.
Local reference points: Cedar Swamp Road (Route 107), Long Island University's Post campus and Tilles Center, and the Brookville Reformed Church.

Questions
Brookville plumbing FAQ
Do you cover all of Brookville?
Yes, all of Brookville (ZIP 11545, 11548), plus the neighboring communities listed below.
Is Brookville 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 essentially all residents on the Jericho 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 Brookville house need?
It depends on the people and bathrooms, not the house's age. Brookville's average owner household is 2.44 people and 96% 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 Brookville?
We answer calls 24/7. We're open Monday through Saturday and closed on Sunday. Call (631) 644-2084.
