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.

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

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.
