Inground Pool Leak Detection
Detecting a leak in an above ground pool is very simple, however detecting an inground pool leak can be extremely difficult. It is however very important that you learn how to do this properly because a leak could end up wasting huge amounts of water which is costing you quite a lot of money. This can also lead to contamination of the water table and may also affect the pH level inside your pool. Although it is difficult to detect a leak in an inground pool it is something that's possible with a bit of hard work.
Step 1 - Inspection
Take time to inspect the inside of your pool taking note of any cracked or loose tiles. You might also notice marshy areas of ground around the pool which could be a result of a leak. If there are problems with wet ground in your back yard then this could suggest you have a leak in your pool.
Step 2 - Algae
Your pool will have chemicals added to it in order to keep algae at bay. If you notice that algae is growing in your pool then this is probably a result of too much fresh water being added to the pool too often which could be caused by a leak.
Step 3 - Bills
If you notice that your water bills are much higher than they normally are then the reason for this could be because more water is being added to your pool as a result of a leak.
If the water level in your pool is dropping by over two inches every day then this suggests a leak. You should only expect to lose around half an inch per day from evaporation.
Step 4 - Filters and Fittings
Any filters or fittings in your pool should be checked for cracks or damage. If any of these are cracked then it could allow water to escape. Concentrate on checking lights and filters as these will be susceptible to damage. If any of these are cracked or have damaged seals then they should be replaced as quickly as possible.
Step 5 - Pool Cover
If you cover your pool during the winter then make sure that it is cleaned of all debris, this includes rain water, ice, snow and heavy leaves. These can weigh the cover down and put pressure onto the water, this can cause water to be pushed out of the pool and sometimes even lead to leaks.
Step 6 - Evaporation Tests
Your pool should lose a certain amount of water everyday through normal evaporation, the evaporation test can help you to confirm whether the water loss is caused by leaks or evaporation.
Fill the pool up to the normal level and make sure that any devices to automatically top your pool up with water are disabled and turned off. Fill a bucket up with water and put it on the step into your pool, use a marker pen to mark the level onto the bucket so that it can be compared later.
Leave the bucket in the pool the whole day and then compare it at the same time the next day. If the pool has lost more water than the level of the bucket then this suggests a leak could be causing the problem.
Step 7 - Thorough Inspection
If the evaporation test suggests leaks then you will need to completely drain the pool of all water and look for cracks or any damage which may need to be repaired. Hire a professional to repair this damage so that you can avoid problems in the future.
