Plumber in King of Prussia, PA

Yes, and the fix is very different. Low pressure at just one faucet almost always means a clogged aerator (the small mesh screen at the faucet tip) or a partially closed isolation valve under the sink - both are quick, inexpensive fixes. Low water pressure throughout the entire house is a more significant issue: it can indicate a failing pressure reducing valve (PRV), significant internal corrosion narrowing your main supply line, a partially closed main shutoff valve, or in older homes, widespread galvanized pipe deterioration. We'll check pressure at multiple points to diagnose which situation you're dealing with.

First: find your main water shutoff valve and turn it off completely. This is usually located near the water meter, in the basement, or in a utility closet. Once the water is off, the damage stops. Then call us - we answer 24/7. While you wait, try to mop up standing water and move valuables away from the wet area. Do not turn the water back on until a plumber has identified and repaired the break. Most burst supply line repairs can be completed in 1–2 hours once we arrive.

Skip the store-bought drain chemicals. Here's why: chemical cleaners generate heat that can warp PVC fittings, they rarely reach deep blockages effectively, and they create a hazardous situation for any plumber who works on the drain afterward. More importantly, a slow drain is often an early sign of a deeper problem - tree root intrusion in the main line, improper pipe slope from settling, or significant grease buildup that will eventually cause a full backup. A plumber can camera-inspect the drain and tell you exactly what's there before recommending the right fix.

This is one of the most common - and most urgent - situations we encounter. What you're likely dealing with is a slow, steady pinhole leak or a sweating pipe that's been dripping into the wall cavity over time. By the time drywall is visibly wet or discolored, significant moisture has usually accumulated inside the wall, and mold begins growing within 24–72 hours of water intrusion. We use moisture meters, thermal imaging cameras, and pressure testing to find these hidden leaks without tearing out entire sections of drywall. The sooner you call, the less remediation you'll need.
