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.
My Pool water gets too hot in the summer to enjoy it. What can I cool it down with?
