Repipe Frequently Asked Questions
What is a repipe?
A repipe is replacing a home's hot and cold water supply lines, typically from the main shutoff and water heater to all fixtures like sinks, toilets, showers, tubs, and laundry.
When does a home need repiping?
A home may need repiping if you have frequent leaks, pinhole leaks, corrosion, low pressure at multiple fixtures, discolored water, or older high risk pipe materials like galvanized steel or polybutylene. Common signs include recurring leaks, water stains, musty odors, rust colored or cloudy water, metallic taste, pressure loss throughout the house, and a history of multiple plumbing repairs.
Is it worth it to repipe a house?
It is often worth it if you are dealing with repeated leaks, low pressure, corrosion, or failure prone piping because it reduces future leak risk and improves reliability.
What are the benefits of repiping?
Repiping benefits include improved reliability, reduced leak risk, better flow and pressure, cleaner water from non corroded lines, updated shutoffs, and fewer emergency repairs.
How much does it cost to repipe a whole house?
Whole house repipe cost depends on fixture count, layout, access, pipe material, permits, and patching. Cost is influenced by home size, number of fixtures, pipe material, access (attic, crawlspace, or slab), permits, and how much opening and patching is needed. An on site evaluation is the most accurate way to price it.
Is it cheaper to replace or repair pipes?
Repair is cheaper when the issue is isolated and the rest of the system is in good shape. Replacement is often more cost effective when leaks are recurring or the material is failing throughout.
How long does it take to repipe a house?
Most homes take about 1 to 3 days for the plumbing portion of a repipe, with extra time if inspections, drywall repair, and texture are included.
How invasive is repiping a house?
It is moderately invasive. Plumbers open access points in select walls or ceilings, run new lines through attic or crawlspace when possible, connect each fixture, then test the system.
Will my house be a mess during the process?
There will be dust and access openings, but a professional crew will protect floors and furniture, contain dust where possible, and clean up daily.
How do I prepare my whole house for a repipe?
Clear access to bathrooms, kitchen, and laundry areas, empty cabinets under sinks, protect valuables, plan for temporary water shutoffs, and secure pets away from work areas.
Do we need to find someplace to stay during a repipe?
Most people can stay home during a repipe, but expect temporary water shutoffs during parts of the day and work areas being opened. Some choose to stay elsewhere for comfort.
What type of pipes are used in a whole home repipe?
Most whole home repipes use PEX or copper for water supply lines. The best option depends on local code, water chemistry, access, and budget.
What is the best pipe to use for plumbing?
PEX and copper are the most common choices. PEX is flexible and corrosion resistant. Copper is rigid and has a long track record. The best choice depends on code, water conditions, and preference.
What is PEX plumbing?
PEX plumbing uses cross linked polyethylene tubing for water supply lines. It is flexible, corrosion resistant, and installed with approved fittings and methods.
What are the negatives of PEX pipes?
PEX negatives can include UV sensitivity (it cannot be left in sunlight), possible rodent damage in some areas, expansion and contraction noise if not secured correctly, and lower heat and fire resistance than copper.
How long does PEX repiping last?
Properly installed PEX commonly lasts several decades, often 40 to 60 years or more, depending on water quality, pressure, temperature, and installation quality.
What type of PEX piping do you install?
Common installations use high quality PEX A or PEX B with approved fittings and methods. The best choice depends on code and manufacturer requirements.
What type of copper piping do you install?
We only use Type L copper for durability. The only time we may use M copper is to run the water heater temperature and pressure relief line.
Does repiping include drain pipes?
Usually not. A standard repipe replaces water supply lines, not drain, waste, and vent piping, unless drain work is specifically included.
Do you include the drain pipes running from the showers and toilets in a standard repipe?
In a standard water supply repipe, drain pipes from showers and toilets are typically not included unless drain, waste, and vent replacement is specifically added.
Will repiping improve water pressure?
Yes, if old pipes are restricted by corrosion or mineral buildup, new properly sized lines can improve flow and often improve water pressure.
Does homeowners insurance cover replacing plumbing pipes?
Homeowners insurance often covers sudden, accidental pipe failures and resulting damage, but usually does not cover full replacement of old piping due to wear, corrosion, or gradual deterioration.
Does repiping lower insurance?
Sometimes, updated plumbing can reduce leak risk and may help with underwriting, but premium changes depend on the insurance carrier and are not guaranteed.
Why don't insurance companies like PEX plumbing?
Some insurers are cautious about PEX due to underwriting preferences and concerns about certain failure causes, often related to installation quality or exposure issues. Acceptance varies by carrier and region.
Why is it more expensive to repipe a slab home than one with a raised foundation?
Slab homes can cost more because routing is more difficult, access may require more cutting, and in some cases special routing is needed to avoid breaking concrete.
When is repiping considered an emergency?
Repiping is an emergency when there is an active major leak, a burst pipe, rapid water damage, loss of water service, contamination risk, or a situation creating electrical or structural risk. Signs include sudden pressure drop, water pooling, hissing sounds in walls, ceiling bulging, a rapidly increasing water bill, or a water meter running when fixtures are off.
What steps should someone take when they need an emergency repipe?
Shut off the main water valve, avoid electrical hazards by turning off power to affected areas if needed, move valuables, document damage, and call a licensed plumber right away.
What are the potential costs of not having it fixed immediately?
Delaying repair can lead to greater structural damage, mold growth, ruined finishes, electrical hazards, and much higher restoration costs.
