What Customers Are Saying

Customers overwhelmingly praise this repair coupling as a fast, reliable solution for fixing broken or leaking PVC pipes in irrigation systems and tight spaces. Most complete repairs in under five minutes by hand without tools or solvents, describing it as foolproof and ideal for emergency leaks. Reviewers appreciate its versatility in confined areas like crawlspaces and value the ability to reuse it over years. The majority report no leaks when installed correctly with firm tightening, with several confirming durability for months or years in low-to-moderate pressure systems. A few note failures under high pressure or when pipes move, emphasizing it works best as a temporary fix.

This is one of the most amazing fix I know!

Would Recommend

Real easy to use, the one thing I’m always worried about is over tightening or not tight enough. Go fig!

Good Product

Would Recommend

This compression repair coupling works good as long as you keep the threads clean and don’t over tighten it. You need channel lock pliers or a pipe wrench to tighten it. Just some info if your new to using one of these.

I have bought 3 of these and all of them have blown out and had water everywhere inside the house. I don't recommend using these at all

Weak temp fix

Would Not Recommend

This item held up for a few weeks in my crawlspace for the main line coming in. Was out for two days and it separated under the pressure. 54,0000 gallons of water later I have a fully flooded crawlspace. Save the headache later, put in the effort to dig out and glue in a proper coupling.

Not for the faint of heart

Would Not Recommend

This fitting, although rated up to 150 psi, does not hold well for water pipe at 90 psi. Our water line has blown this fitting off three times. The ONLY way to use it with confidence at this pressure is to 1) bury the line securely so it cannot wiggle out. 2) add additional secure locks to the pipe so it cannot wiggle free. 3) use ONLY as a temporary repair I am sure it works great at normal house pressures, but our water supply is a very high pressure

Good product for selective use

Would Recommend

This is a great item to splice a line with that you need access to on a regular basis. I've personally had the best luck using these in lower pressure situations such as my pool plumbing and on an aquarium. Just make sure you push in the pipe as far as it can go.

Quick plumbing fix.

Would Recommend

Used this on a condensation drain line. Now I have an easy compact way to break the line for maintenance.
