What our customers are saying
The overall experience was great. The only problem I had was when I tried to find the option of where I would like to pick up my order, it would not allow me to do so at the Surprise location. Dan, from the Surprise location kept in contact with me that same day I put the order in and was able to take my order to the Surprise location as he had been to the warehouse and said he could take it with him, In the end, it all worked out. Thank you Dan for helping me out, very much appreciated!

FAQ
Our expert staff answers customer's most asked questions.
What is the function of the Vaclock, and how do I replace it?
Determine whether your Vaclock is threaded or slipped. If threaded, carefully unscrew it. If there are broken pieces, gently chip them out without damaging the threads. For a Slip Vaclock replacement, cover the top with a towel or rag and use a rubber mallet to tap in the new one.
How often should I test my pool water?
Regular testing, ideally once a week, ensures that chemical levels are within the recommended range. This practice ensures that your pool is always ready for enjoyment.
What is the recommended duration for running my pool equipment?
There isn't a specific timeframe, but it's essential to complete a full water turnover within a 24-hour period. Utilizing pool equipment during off-peak hours can be cost-effective.
