What Saw Mill Valley is
Condo listings name Saw Mill Valley as a subdivision, including second floor end units with a monthly association fee and association maintained decks. Listings place it in the Hatboro-Horsham School District, near the Pennsylvania Turnpike and Routes 309 and 611.
The township plan counts about 1,175 single-family attached homes and about 2,300 multifamily units out of roughly 10,300 housing units, so condos and townhomes make up a large share of Horsham. We do not state a build year for Saw Mill Valley because the listings we found did not give one.
Where the association ends and you begin
Condominium documents decide who owns and repairs what. The usual pattern is that the association handles shared lines, risers and common areas, while you handle fixtures and supply lines that serve only your unit. Your declaration and bylaws are the final word, so read them.
Questions to answer before work begins
- Does the pipe serve only your unit, or several?
- Is it inside a shared wall or floor?
- Does the association require notice, a form or a licensed contractor?
- Does the association carry coverage, and does yours cover interior damage?
- Who pays if a leak damages the unit below?
If the answer is unclear, call the manager before a plumber opens a wall. It avoids disputes and sometimes avoids a repair bill.
Leak or backup in Saw Mill Valley?
Call (215) 714-6692 and tell us the unit type, the floor and what you see.
Leaks in upper and lower units
Upper floor unit
A slow leak under a sink or behind a toilet can run to the unit below before you notice. Check the supply valves and the floor around fixtures.
Ground floor unit
A stain on a ceiling or wall may come from above or from a shared line. Photograph it and tell the manager.
Water bill creeping up
Horsham Water and Sewer Authority explains a quiet meter test, and a moving dial with nothing running points to a leak on your side.
Toilet that keeps running
A dye tablet in the tank for about 20 minutes shows whether the flapper leaks. It is a small fix that wastes a lot of water.
For hidden leaks, see leak detection. For a failing shutoff or supply line, see water line repair.
Water heater swaps and the township permit
Horsham Township lists plumbing fixtures, water heaters included, among the work that needs a permit. Code Enforcement can be reached at (215) 643-3131, and inspections generally need 24 to 48 hours of notice. In a condo, your association may also require approval before you change a heater or venting.
For options, see water heater replacement and water heater repair.

It depends on your declaration and whether the pipe serves one unit or several. Ask the manager and photograph the damage before repairs begin.
Many associations require notice or approval. Horsham Township also lists water heaters among the work that needs a permit, so check both.
With everything off, read your water meter and read it again later. A moving dial suggests a leak on your side of the meter.
