Wisemans Everclens Kit Tankless Water Heater Descaling Kit (CLENS-KIT) is designed to be used with tankless water heater 3/4" hot and cold drain connections in order to clean and flush out your system with the provided 1/4 hp pump. The Everclens kit does not contain harmful mineral acids and its unique organic formulation is fast acting, non- hazardous, non-toxic and operator safe. EVERCLENS; is harmless to septic tanks and is environmentally friendly.


The following steps outline a general procedure for using the CLENS-KIT to descale tankless water heaters. Your heater’s manufacturer may have more specific instructions, which should be followed for descaling your particular appliance.

The CLENS-KIT was designed to be used in conjunction with tankless water heater isolation valves that provide ¾” hot and cold drain connections. If these valves are not in place, the heater can be disconnected from the plumbing system and drained, and the CLENS-KIT hoses connected directly to the cold and hot water connections.

  1. Disconnect the power to the water heater.
  2. Close the hot and cold system isolations valves.
  3. Ensure that the cold and hot drain valves are closed, and remove the drain caps.
  4. Connect one of the hoses to the pump. Connect the other end of the same hoses to the cold drain valve.
  5. Connect the other hose to the hot drain valve. Place the other end of the same hose into the bucket.
  6. Pour entire contents of one 1/2 litre bottle of EVERCLENS Tankless Water Heater Descaler into the bucket.
  7. Add approximately 2 gallons of water to the bucket – bucket should be about ¾ full.
  8. Open both the cold and hot drain valves.
  9. Plug the pump into a grounded receptacle. The pump will turn on.
  10. Circulate the EVERCLENS solution through the heater for 15-30 minutes.
  11. Unplug the pump.
  12. Close the cold drain valve, remove the hose and replace the drain cap.
  13. Remove the pump from the bucket and discard the solution. Organic EVERLCENS is safe to dispose of in drains.
  14. Flush the heater for several minutes by opening the cold system isolation valve and allowing the water to exit through the hot drain valve into the bucket or to a drain.
  15. Close the drain valve, disconnect the hose and replace the drain cap.
  16. Open the hot system isolation valve.
  17. Connect power to the water heater and return the appliance to service.
