High chlorine level in the spa
Too high a chlorine concentration can damage the hot tub - from staining the tub and warping the PVC to degrading the heater or filter pump. Always test the water before adding chlorine, and always blow out and store the hot tub if it is inactive for long periods of time.

High/low pressure in Sand filter Pumps
Pressure problems in the sand filtration can be caused by improper installation, the presence of air bubbles, or contaminated filter media. Low pressure is often related to inadequate system venting, while high pressure indicates the need for backwashing. Proper positioning of the pump below the water level is also important.
