How To Fix A Leaky Compression Fitting
Here are a few reasons why your compression fitting may be leaking and how you can fix it.
A leaky compression fitting isn’t only a massive inconvenience, but it can also be a rather expensive issue if you don’t fix it right away.
Designed to connect two pipes, plasson compression fittings have three parts – the compression nut, ring and seat.
When these parts become worn or damaged or weren’t installed correctly, you’ll likely experience problems with leaks.
But what causes this, and how do you repair a leaky compression fitting?
What causes leaky compression fittings?
There are many reasons why your compression fitting could be leaking, including:
- Incorrect installation
When pushing the fittings onto the pipe, you must ensure that the pipe is fully inserted.
If the fitting isn’t fitted properly, it will not create a watertight seal and you’ll experience leaks.
When inserting the pipe, you should feel a resistance point but don’t let this trick you into thinking it’s inserted all the way.
Remove the pipe and make a mark, to indicate how far the pipe needs to go in to reach halfway into the fitting.
- Excessive pressure
Leaks can happen when your fittings are under too much strain or pressure, particularly if your installation involves a pipe or fitting that’s on an angle.
The pressure could potentially stretch the O-ring, which means it won’t be able to function as it should and may start to leak.
Plasson compression fittings are designed to manage this problem.
Elbow fittings, either 90◦ angles or short radius 45◦ angles, are angled to change the direction of water and swivel elbows allow you to fully rotate one end so your pipe and[AG1] face whatever direction it needs to.
- Pipe issues
If the end of your pipe is jagged or uneven, you will not be able to achieve a watertight seal.
This is why it’s so important to make sure your pipe has a clean, straight cut.
To avoid this issue, make sure to use a pipe cutter, rather than a blade or saw that you might have in your toolbox.
How can I fix it?
Most professional plumbers would agree that the best thing to do is loosen and retighten the compression nut.
Before you attempt this, make sure to turn off your water, as leaving it on will cause a slippery mess.
You should also have a bucket and towel on hand to catch any water that may leak while you’re attempting to loosen the nut.
Once everything is secure again, switch your water back on and see if it’s still leaking. If it is, then you’ll probably need to replace it.
