There are many types of swimming pool and spa leaks. You may be experiencing more water loss with the equipment running for example, this would indicate to us the problem is most likely going to plumbing related. However, if the pool or spa leak does not seem to be affected by the filter pump you are more than likely experiencing a leak in the shell. It is this knowledge and experience that separates us from the rest,  and it is why we can save you money. Knowing where to look is as valuable as any piece of our equipment.
