Plumber in Prospectville, Horsham, PA

A crossroads village, not a subdivision

Prospectville was once called Cashtown. It grew around a tavern at a stop on Limekiln Pike, a road that extends a 1693 route between Old York Road and lime kilns in Upper Dublin. It sits at about 351 feet of elevation, one of the higher points in the township.

Today it is a crossroads at Routes 152 and 463. Graeme Park, a 42 acre historic park whose Keith House is the township's only National Historic Landmark, is nearby. Mail goes through the Ambler post office under ZIP 19002, though the village is in Horsham Township and the Hatboro-Horsham School District.

Township officials have discussed a village zoning district for years, citing walkability and nicer restaurants and stores, and say the idea appears in township planning documents from 2011 and 2024. We describe it as the plan says and do not predict what gets built.

Two kinds of calls here

For homeowners at the crossroads

Homes around Prospectville use the same Horsham rules as the rest of the township, so the practical steps are the same. Find your main shutoff and confirm it turns. Locate the cleanout on your sewer line before a backup. Read your water meter with everything off to check for a quiet leak.

If you are not sure whether your home is on public sewer or a private system, ask the Authority at (215) 672-8011 before any work. It saves a wasted visit and a wrong assumption.

Grease interceptors and restaurants

Horsham Water and Sewer Authority's rules require grease, oil and sand interceptors in all industrial and commercial establishments, and the owner maintains them at their own expense. Chemical dispersants need the Authority's approval.

For a restaurant, a slow kitchen drain is often a sign that the interceptor is full. For a shop or office, the interceptor may not apply, but the same Authority rules still cover what goes down the drain. See commercial plumbing and sewer line cleaning.

Backflow and cross connection

The Authority also requires customers to comply with its Cross Connection Control and Backflow Prevention Program Policy. We did not read that policy in full, so we cannot say which properties must test or how often. Call the Authority at (215) 672-8011 to ask.

Permits

Horsham Township lists plumbing fixtures, including water heaters, among the work that needs a permit. Code Enforcement can be reached at (215) 643-3131. Before any digging, Pennsylvania law requires a call to 811 at least three business days ahead.

For a home, see drain cleaning and water heater replacement. Prospectville uses an Ambler mailing address, and our Ambler plumbing page covers the borough, which is a separate municipality.
