I told my neighbor Charles that the Almaschool pickup location was no longer an option when I placed an online order. Charles took the time to pick it up for me (25mi further) and even dropped it off at my backyard. Thanks Charles I appreciate it very much!

FAQ
Our expert staff answers customer's most asked questions.
Are open box items still under warranty?
The warranty status of open box items may vary. Most open box products fall under brand new warranties. It's best to check with the seller or Pentair directly about the specific warranty coverage for open box purchases.
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.
What are the ideal chemical ranges for my pool?
Achieving a balanced pool involves maintaining a pH range of 7.2–7.8, total alkalinity between 80–120 ppm, calcium hardness at 180–220 ppm, and cyanuric acid (stabilizer) within 30–50 ppm. Chlorine levels should consistently fall within the 1–3 ppm range, by may need to be increased as CYA levels go above 60 PPM.
