I bought a demo/open box chlorinator from them. So far the product has been working well (one week) and it looked new in the manufacturers box when I got it. Communication with them was great. Price I got for the open box item was worth it. Would use them again. Thanks.

FAQ
Our expert staff answers customer's most asked questions.
What is the difference between E-commerce (EC) and Trade pricing?
E-commerce pricing is our standard online retail pricing available to all customers. Trade pricing is exclusively for pool maintenance professionals and typically offers better rates. To get Trade pricing, you'll need to request a personalized quote.
How many BTUs does my heater need to heat a pool or spa?
The ideal BTU rating for your heater depends on your desired heating speed. A 200 BTU or 250 BTU heater is suitable for a spa or pool, while a 400 BTU heater will heat your pool and spa more rapidly.
Are there discounts on Open Box products?
Yes, we offer discounts on Open Box items. However, these prices are often too low to advertise online as they fall below Minimum Advertised Price (MAP) guidelines. Contact us directly for the best deals on Open Box products.
