How To Find a Leak In a Pool Return Line?

You’ve often heard of how critical a pool system’s return line is in maintaining and cleaning the water in your pool.

However, you may not know that if your return line is not functioning, your system may be filling with water instead of sucking it out.

How To Find a Leak In a Pool Return Line

As every pool owner is well aware, this gravity-fed scenario presents a significant problem. If the return line ever fails or leaks somehow, there is a good chance you will end up with excess pool water all around the house; likely in places you don’t want it.

Every homeowner knows that the only way to have a pool running for long is to check for leaks during the swimming season regularly.

That is why having a leak detector capable of detecting leaks even at low-pressure levels is essential if you want to avoid unnecessary repairs and expenses.

How To Find a Leak In a Pool Return Line?

Here are some steps that you should follow in this regard.

1. Check your filter:

If you have an automatic turn-off switch for the pump or filter, check this area as well to see if water is leaking through it from somewhere near the return line in your pool. You will not detect a leak if the water is not visible.

 

2. Check your pump:

If you have a manual turn-off switch for the pump, inspect it to see if there are signs of leakage around where they attach to the return line at its fitting or elsewhere in this area.

If there is any damage to the piping, you will probably see a water leak that can be repaired.

 

3. Check your return line:

If you leak the pool return line, inspect it to see any discoloration or damage around where they attach to the fittings. Also, check for holes and gaps in this area as well. You may find that some of these holes and cracks are caused by gaskets that have become loose.

 

4. Check your return hose:

If you do not detect a leak in the pool return line but notice discoloration or damage to this area, check the rest of it to see any other damage that leaks may have caused.

 

5. Check your water levels:

Check your water levels regularly. If you notice excess water, it can probably be attributed to leaks in the pool return line.

You should inspect this area and look for any signs of leakage, such as discolored or stained areas around the pipe fittings or holes where they have been removed.

 

6. Check your pump motor and wiring:

If you have a manual turn-off switch for the pool pumps, check this area to see signs of leaks around where they attach.

Also, inspect any exposed wiring that may be damaged or in bad shape. If the wires look like they have been chewed or cut, you may find leaks there as well.

Why Does a Leak Come In a Pool Return Line?

There are a few potential sources of water leakage in your pool return line. A common culprit is using a weak or corroded thread at the end of the line.

Over time, this can lead to leaks as pressure builds up inside the system and eventually breaks through. Another common issue is leaky rubber coupling.

These can be caused by various factors, such as exposure to sunlight, age, and shoddy repair work.

The last possibility is the presence of algae growing inside the return line itself. This will look like a faint white streak in your waterline that may not even show up on your daily pool maintenance check.

 

Why Is It Essential To Find a Leak in a Pool Return line?

If a leak is not detected and corrected, it will eventually cause your pool to fill up with water.

This can lead to severe problems, such as damage to the equipment and walls of your pool, potential injury when diving in or walking on the water surface, and even loss of money due to unnecessary drain and pump repairs.

It is essential to look for a leak in the return line of your pool as soon as it appears before the problem gets worse.

This way, you can begin taking action immediately to prevent damage from occurring. Plus, you will also be minimizing the cost associated with repairs.

 

How Do You know IF There Is a Leak in The Pool Return Line?

A leak detection system will detect even small amounts of water, so it can learn how much pressure is being applied to your plumbing. As these changes over time, it will make an alert sound when it detects a leak.

For this reason, it is essential to maintain proper water levels in your pool so that you can see the effects of leaking pipes on your return line and repair them before they become more severe.

If you have an automatic turn-off switch for the pump or filter, do not forget to turn it on when your pool is not used to reduce the amount of water and air lost through leaks.

 

How To Fix A Leak in A Return Line?

There are a few things that you can do to fix a leak in the pool return line. If you have detected discoloration or damage to this area, your first step is to check for any signs of leakage.

This includes looking for any signs of water leaking from around the fittings that hold these lines together. You can also check for holes and gaps in the pipe itself to see loose or damaged.

If you find leaks, you will want to get them fixed as soon as possible. Make sure not to leave any exposed areas of piping like this one alone until you have repaired it.

 

Final Thoughts

If you have detected a leak in your pool return line, make sure to check for signs of water leaking from around the fittings and look for any damage or holes where leaks could occur.
