Tips

  • Using plastic push-fit pipes offers the advantage of expansion and contraction during freezing temperatures, reducing the risk of future pipe bursts compared to copper pipes.

Common Mistakes to Avoid

1. Incorrect Pipe Sizing

Reason: Using push-fit fittings that don't precisely match the diameter of your pipes can lead to leaks and a weak connection.
Solution: Always double-check the pipe and fitting diameters before connecting them and ensure a snug, secure fit.

2. Insufficient Depth of Insertion

Reason: Not pushing the pipe fully into the push-fit fitting until you hear a distinct click or feel the proper resistance can result in a loose connection and leaks.
Solution: Push the pipe firmly and completely into the fitting until it is fully seated and you hear/feel the secure connection.

FAQs

Are push-fit fittings a permanent solution for a burst pipe?
No, push-fit fittings are designed for temporary repairs. While they effectively stop the leak quickly, they are not as durable or long-lasting as traditional soldered or compression fittings. They should be replaced with a permanent repair as soon as possible.
