Water leaking from the base of the Hewalex pool heater onto the ground.

Safety first: Turn off power and close water valves before tightening or opening any water connections.

• Identify water type: Feel the water. Condensate is usually clear and cool; pool water may have chlorine smell or color.
• Check unions: Inspect inlet and outlet unions on the Hewalex heater for drips. Tighten by hand, then slightly with a wrench if needed, without over‑tightening.
• Inspect piping: Look for cracks or loose joints in PVC pipes near the heater and repair or replace as necessary.
• Condensate management: Ensure the condensate drain outlet is clear and connected to a suitable drain line so water does not pool under the unit.
