Incredible prices & free shipping for name brand products, not cheap knock offs! I placed my order on Sunday and received shipping confirmation on Monday! Filters arrived in the original Pentair Shipping carton the next day. Excellent company and service while saving big over the local pool store and cheap knockoff from large online retailer!

Outstanding support! Customer service has prompt responses and solutions to your pool needs. I am very happy with a replacement suction vacuum solution that was suggested. I bought it and it shipped to my home in 3 days. Great job and a pleasure doing business with this pool company.
