Longview Plumber
Burst Pipes to Clogged Drains — 24/7 Emergency Plumber Serving All of Cowlitz County

Original plumbing from the 1920s and 1930s has exceeded its expected lifespan by decades. While some cast iron drain lines can last 80-100 years under ideal conditions, Longview’s heavy rainfall and active root environment means most have deteriorated significantly. Galvanized supply pipes from this era are almost certainly heavily corroded internally. And importantly, solder used on copper joints before 1986 often contained lead, which can leach into your drinking water. We strongly recommend a comprehensive plumbing inspection for any pre-1940 Longview home, including a lead test on solder joints and a camera inspection of drain lines.

If roots keep coming back, it means they have a persistent entry point—usually a cracked joint, offset pipe, or deteriorated connection. Annual root cutting treats the symptom, not the cause. For Longview’s older sewer laterals, we offer two permanent solutions: trenchless pipe lining (CIPP), which inserts a resin-coated liner that hardens inside your existing pipe to create a jointless, root-proof barrier, or conventional lateral replacement, where we install a new PVC sewer line from your home to the city main. We’ll camera-inspect your lateral and recommend the most cost-effective permanent fix based on its specific condition.

In Longview’s older homes, low water pressure is almost always caused by galvanized steel supply pipes that have corroded internally. After 60-100 years, the inside of a galvanized pipe can be so clogged with rust and mineral buildup that the effective diameter is reduced from 3/4 inch to less than 1/4 inch. No amount of faucet replacement or pressure adjustment will fix this—the pipe itself is the restriction. A whole-home repipe to PEX will restore full water pressure and is typically the most impactful upgrade you can make to an older Longview home.

Significantly. Longview receives roughly 46 inches of rain per year, well above the regional average. This volume of rainfall affects plumbing in several ways: saturated soil increases hydrostatic pressure on below-grade drain lines and sewer laterals, promoting infiltration through cracks and joints. Storm events can overwhelm the city’s combined sewer-storm system in some older areas, causing backups. And constant moisture in crawl spaces accelerates corrosion on pipe fittings and supports. We recommend annual inspections of crawl space plumbing, a functioning sump pump for homes with below-grade spaces, and a backwater valve to prevent sewer backups during heavy storms.

Yes, and we do it regularly. Our approach to repiping older Longview homes minimizes wall and ceiling damage by routing new PEX supply lines through existing pipe chases where possible, using attic and crawl space runs to reach fixtures, and making surgical access holes that we patch neatly when finished. For drain lines, we evaluate whether the existing cast iron can be lined in place (avoiding wall opening entirely) or whether targeted replacement of specific sections is sufficient. Our goal is always to modernize the plumbing while preserving the home’s historic character.
