Yes, a pool sand filter can be too big, causing poor water clarity due to insufficient backwash velocity and channeling. Proper sizing should match your pump's flow rate at 15-20 GPM per square foot of filter area.
You need a bigger pool pump if it can't turn over your entire pool volume in 8-10 hours, struggles to maintain proper circulation, or can't effectively run your pool equipment. Calculate your required flow rate based on pool volume and equipment needs.
Yes, you need a bypass for your pool heater to control water flow, prevent damage during maintenance, and ensure proper operation. A bypass allows you to divert water around the heater when needed and regulate flow rates for optimal heating efficiency.
