Material and Labor Costs

The material cost for PEX tubing ranges from $0.50 to $1.50 per foot, with SharkBite PEX-B and Uponor AquaPEX being popular choices. Fittings, manifolds, and valves can add $500 to $1,500 to the total cost. However, labor is the primary cost driver, often accounting for 60 to 75 percent of the total expense.

Common Scams and How to Avoid Them

Be wary of common scams, such as contractors pushing unnecessary full manifold system upgrades or inflating drywall repair costs. Always ask for a breakdown of labor, materials, and wall repair costs, and ensure the quote includes a full repipe to all fixtures without exclusions.
