At times, the problem can seem so big that it’s hard for us to think of solutions. And we can miss the first step. Avoid that trap by starting here!
- CHECK OBVIOUS AREAS FIRST
Check where your equipment is kept. You’ll need to look closely at:
- The filtration system
- The pump
- The heater
- Each of the valves
The plastic skimmer often separates from the concrete pool edge. Since it’s common, it’s a good thing there’s an easy fix. Simply re-attach it with a pool putty.
- Give the light fixtures a close look. Leaky lights are hard to fix, but worth the effort.
- Now you can move to the surface.
- Turn off the pump and let the water become still.
- Pour some pH Indicator Reagent into the pool near any visible cracks. Watch closely to see if it moves closer to the crack (or even gets sucked out). If it does, the crack is deep and leaking water.
- DO THE BUCKET TEST
Now it’s time to get scientific. We all know that water evaporates out of pools. So here’s how to find out if that’s the only way your pool is losing water. Hopefully, it is. Run the test during a 24-hour period when you’re fairly sure it won’t rain. If it does rain, start the test over.
- Turn off the pump off and let the water settle down.
- Fill a 5-gallon bucket with water (around 2/3 full). Add weight by putting bricks or sand in it.
- Set the bucket on the pool stairs. It should be about half underwater. Make sure no water will splash into it.
- Carefully mark the level of the water in the bucket. Mark it inside. Then, mark the pool water level on the outside.
- Wait for 24 hours. This is the easy part. Go on with your day. The next day, carefully measure how much the water level in the bucket went down. Then, measure how far the water in the pool went down on the outside of the bucket. Compare the two measurements. Unless your bucket leaks, the only way its water level went down is through evaporation. If the pool water level went down more than the bucket water did, your pool is leaking.
- CHECK THE PUMP AND FILTER
If you know your pool is leaking (here’s hoping you don’t need to do this step), you need to find the leak. Does the plumbing leak? The filtration system? Or the pool shell? Let’s check the filter and pump first.
- Fill the pool all the way. That means up to the tile or skimmer.
- With still water, mark off how high the water comes on the side of the pool.
- Now, turn your autofills off (or check to make sure they are). Then, turn on the pump. You’ll let it run for 24 hours.
- After 24 hours, head back to the pool and check the water level. Has it gone down? Of course, since water evaporates. Now you’ll measure how far it went down and compare it with how far it went down during the bucket test.
- If your pool has lost more water than evaporation would indicate, then your plumbing system may be losing water.
- Run the pump in the filter position, then inspect the backwash line. If there’s any water leaking from it, then it’s time for you to repair or replace the filter valve – pronto.
- NOW TURN THE PUMP OFF
If, after inspecting the pump, you can tell that it’s not the source of the leak, turn it off. Now you’re going to test the pool shell and lining. As in step 3, make sure your pool is full up to tile or skimmer.
- Mark off how high the water comes on the wall of the pool or inside the skimmer.
- Turn off the pump after first double-checking any autofills to make sure they’re also off.
- After 24 hours, check how far the water level has dropped. Again, keep evaporation in mind by comparing the drop with your bucket test measurement.
- If, with the pump turned off, the water in your pool is less than it should be, you probably have a pool shell or liner leak. But if the level dropped significantly more when your pump was switched on, the plumbing system is most likely to blame.
NOW WHAT?
All this testing is worth it. If for no other reason than to give you peace of mind. Now that you know how to check your pool for leaks, follow these steps each year before pool season starts. More than likely, your pool is only losing water through evaporation. If you check your pool for leaks and find one, it’s probably visible and you can fix it yourself.
What if you doubt your ability? Is the pool leaking and you can’t find the leak? In that case, you might need to get professional repair help. Call us and let’s get a leak detection scheduled!
