We have used Splash Pools for approximately 3 years and couldn't be happier. We have not had one problem since we have used them and the people who referred them to us have never had a problem in 4 1/2 years. Everyone has been very polite and we love the guy who services our pool. He checks the balance and adds liquid chlorine as well as putting chlorine tablets in our chlorinator. If you want additional service, of coarse it is offered to you. As with any service you are responsible to run your pump to make sure the water circulates long enough.
