How To Repair Cpvc Pipe Without Cutting

The Basics of Repairing Aged CPVC Piping

As with any crumbling process, CPVC plumbing piping that has been performance for years tin can change in advent with the passage of time. Discoloration tin happen, but if the pipe is FlowGuard® CPVC, that will not affect the life expectancy of the pipe system or its pressure begetting capabilities under normal use atmospheric condition.

However, there is a misconception that older CPVC pipe is hard to repair. This is not the case, if the pipe is handled with care and the right tools are used. Merely follow these steps and review the day's piece of work later each shift to ensure the all-time repair possible:

Dry out the arrangement out to get residual water out of the joint. Make certain that dirt has been wiped away with a clean material. Besides scrape or sand off any paint that is adhered to the pipe. Old paint volition interfere with the solvent welding procedure and/or overstress the fitting, possibly causing information technology to fissure.
Verify that you lot take a proper interference fit by inserting the pipe easily 1/3 – 2/3 of the depth into the plumbing equipment, every bit you would with a new installation. It'southward this disquisitional expanse that will provide 80% of your joint strength.
Make a clean, square cut using but a C-manner tubing cutter (shown at right), a wheel cutter or a fine-tooth saw, non a ratchet or pair of scissors-style cutter. This is the way to provide the largest surface for a strong solvent cement bond.
Chamfer and deburr the pipe to prevent its sharp square edge and/or the cut debris from scraping too much of the cement off the surface of the socket. This helps to avoid creating a leak path through the joint.
Check again that the joint is dry before standing with the usual solvent cement process. Apply the solvent cement to the CPVC fitting and pipe with a dauber, and then quickly quarter-turn the pipe into the fitting to evenly spread the solvent.
Be vigilant by solvent cementing each joint as it is installed. Errors can occur when the system is not installed joint by joint. At that place should be a bead of xanthous solvent cement on each articulation.
Follow the solvent cement manufacturer's recommendation for set and cure times.

Whether it's a new install or a needed repair, ever keep in mind that when joined correctly with solvent cement, the molecules of FlowGuard® CPVC pipe and fittings are mingled and bond together, with the resultant joint becoming the strongest part of the piping system. That's the peace of listen that comes from a combination of pipe cloth advances and superior plumber workmanship!
