Frequently Asked Questions

Have questions about plumbing in Portsmouth? We have answers.

Is it safe to use chemical drain cleaners in my Portsmouth home?

Chemical drain cleaners can damage older pipes in Portsmouth homes, especially PVC, brass, or aging galvanized plumbing. The caustic chemicals can eat through pipe walls over time and are hazardous if they splash on skin or eyes. A professional drain cleaning by Phoenician Plumbing is safer, more effective, and prevents pipe damage — costing less in the long run.

How can I tell if I have a slab leak in my Portsmouth home?

Signs of a slab leak in Portsmouth homes include unexplained increases in your water bill, warm or wet spots on the floor, the sound of running water when all fixtures are off, cracks in the foundation or walls, and low water pressure. If you notice these symptoms, call a plumber for professional slab leak detection before the damage worsens.

How do I prevent frozen pipes in Portsmouth, NH?

To prevent frozen pipes in Portsmouth, insulate exposed pipes in unheated areas like garages, crawl spaces, and attics. Keep cabinet doors under sinks open during cold snaps. Let faucets drip slightly during freezing temperatures. If a pipe does freeze, call Phoenician Plumbing immediately rather than attempting to thaw it yourself to avoid a burst.

What is the difference between a plumbing repair and a repipe in Portsmouth?

A plumbing repair addresses a specific problem — a broken pipe, a failed joint, a leaking valve. Repiping replaces the entire water supply system throughout your Portsmouth home, typically because the existing pipes are too corroded or deteriorated to repair reliably. If your Portsmouth home experiences frequent leaks or has galvanized or polybutylene pipes, repiping may be the more cost-effective long-term solution.

How much does a plumber cost in Portsmouth, NH?

Plumber rates in Portsmouth typically range from $100 to $250 per hour depending on the type of work and time of day. Common jobs like drain cleaning run $150 to $300, while slab leak repair and repiping projects cost significantly more. Phoenician Plumbing provides free estimates so you know the full cost before any work begins.

How often should I have my drains cleaned in Portsmouth?

Most Portsmouth homeowners benefit from professional drain cleaning every 1 to 2 years as preventive maintenance. Homes with large families, frequent cooking, or older plumbing may need service more often. Tree roots, grease buildup, and hair are the most common causes of drain problems in Portsmouth. Phoenician Plumbing uses hydro-jetting and snaking to thoroughly clear all drain types.
