Easy Guide to Repiping House with PEX: Cost, Process & Benefits

Repiping House with PEX: A Complete Guide

Repiping your home involves replacing your old water pipes with new ones. If you're considering updating your plumbing, this guide covers everything you need to know about repiping your house with PEX (cross-linked polyethylene) pipe.

Why Repipe with PEX?

PEX has become a popular alternative to copper pipes due to its flexibility, durability, and cost-effectiveness. Here’s why you might consider PEX for your home:

• Flexibility: PEX is flexible, making it easier to install in tight spaces and reducing the number of fittings needed.
• Durability: PEX is resistant to corrosion and mineral buildup, extending its lifespan.
• Cost-Effectiveness: PEX is generally less expensive than copper, which can save you money on materials and installation costs.
• Fewer Leaks: PEX connections are more resistant to freezing and bursting compared to rigid pipe systems.

The Repiping Process

Repiping a house involves several steps:

1. Inspection and Estimate: A plumber will inspect your home and provide an estimate for the repiping work.
2. Preparation: The plumber will protect your belongings with plastic coverings, as they'll need to cut holes in the drywall to access the pipes.
3. Pipe Selection: You'll choose between PEX, copper, and CPVC pipes. A certified plumber can help you decide.
4. Repiping: The old pipes are removed and replaced with new PEX pipes.
5. Testing: The new system is tested to ensure there are no leaks.
6. Restoration: Holes in the walls are patched, and the house is cleaned.

Choosing the Right PEX System

There are different methods for PEX installation:

• Trunk and Branch System: A main PEX line (the trunk) runs through the house, with smaller branches extending to individual fixtures.
• Home Run Manifold System: Each fixture has a direct PEX line running back to a central manifold. This can provide more consistent water pressure.

DIY vs. Professional Repiping

While some homeowners may consider DIY repiping, it's generally recommended to hire a professional plumber. Professional plumbers have the expertise and tools to ensure the job is done correctly and safely. Furthermore, using a professional ensures that the work complies with local building codes and regulations.

Cost of Repiping with PEX

The cost of repiping a house with PEX can vary depending on several factors:

• Size of the House: Larger homes with more fixtures will generally cost more to repipe.
• Complexity of the Plumbing System: Homes with complex plumbing layouts may require more labor and materials.
• Local Labor Rates: Plumbers' rates vary by location.
• Materials: While PEX is typically cheaper than copper, prices can fluctuate.

Factors Influencing Repiping Cost

• Obtaining permits before starting any major plumbing project is advisable.
• Repiping a house without shutting off the water supply is not possible.

Benefits of PEX Repiping

• Improved Water Quality: PEX pipes don't corrode, so you'll enjoy cleaner, healthier water.
• Increased Water Pressure: Replacing old, narrow pipes with new PEX can improve water pressure.
• Fewer Leaks: PEX is more resistant to freezing and bursting, reducing the risk of leaks.
• Increased Home Value: A repiped home with PEX can be more attractive to buyers.
• Pace of Mind: Knowing your plumbing system is new and reliable can give you peace of mind.

Potential Challenges

• Cutting into Drywall: Repiping requires access to the pipes behind walls, which means cutting into drywall.
• Temporary Water Shutoff:The water supply needs to be temporarily shut off during the repiping process.
• Disruption:The repiping can be disruptive to your daily life.
