Plumber in King of Prussia, PA, from Phoenixville

King of Prussia, in Upper Merion Township, took its name in the 1700s from the old King of Prussia Inn, and the area around Valley Forge holds some genuinely old housing. But KOP is also one of the fastest-changing places in the region, wrapped around the largest mall on the East Coast. The newer townhomes and developments that have filled in around it are a very different plumbing proposition from the older homes near the park.

That split is the thing to know about plumbing here. In the older Valley Forge and Gulph Mills homes you find the same aging supply and drain materials as any pre-war house. In the newer construction it is modern plastic supply and a different set of issues, water heaters reaching the end of their first run, fixtures wearing out, the ordinary maintenance of houses built in the last few decades.

In King of Prussia's newer developments the questions are different from the old-house ones. These homes were plumbed with modern plastic supply and manifold systems, and the calls tend to be about builder-grade fixtures reaching the end of their run, water heaters hitting the ten-year mark, and the occasional quirk in how a development was originally plumbed.

Because so many homes in a community went in at once, they often age on the same schedule, so when one neighbour's water heater fails, others on the street are usually not far behind. We keep that in mind, and when we replace a unit we are happy to tell you honestly whether yours was early, on time, or overdue for the batch. It is a small thing, but it lets a homeowner plan the next replacement rather than be caught out by it on a cold morning.
