SKU: LEAKSTOP
Product Description

Leak Prevention Protector

  • When wettened by a leak this compact highly effective new gadget shuts down your water flow within as little as 3 seconds.
  • Special moisture sensing material activates Rapid Expansion Tissue which stops the flow of water into your filtration unit.
  • Additional pressure reducing valve decreases incoming water pressure to 3 bar. Prevents water surge risk and damage to expensive equipment.
  • No batteries or electricity required.
  • Manufactured with top quality materials including hard wearing acetal thermoplastic for increased durability.
  • Simple 1/4" Quick Connections (QC) for easy installation.
  • Spare expansion plug included with the unit.

Easy to Install

This smart little device comes with full step-by-step instructions.

Basically you simply insert it on the tube going into your water filter.

You can easily cut the plastic tubing with standard kitchen scissors and push either side of the tube into the quick connect in / out ports on your new leak stop.

If your existing tubing is 1/4" it can be inserted directly into the device. If you have different size tubing you should easily be able to get a straight connecting adapter eg from here

Advice with regard to installation of new products has been generously given and would recommend this company without reservation.”

Frank Woodhead

“I have used UK Water Filters for many years now and never had a bad experience. From ordering to delivery it takes just a few days. They always send a polite email to check we have received our filter. I wouldn't think of using another company.”

Sandra Hutchinson

"We are very happy with the service provided by UK Water Filters. They have given us good advice and prompt service. We will be reordering with them again and wouldn't consider ordering anywhere else."
