Abstract

A water leak detection system 1 comprising at least one water sensing station 10,11,12,13 to detect water or moisture and in the floor 2 of a building and a monitoring station 20 connected to the water sensing station to generate an alarm signal when a water sensing station detects water or moisture. Water sensors 10A/B, 11A, 12A/B, 13A may be fitted singly or in vertically spaced pairs and may be of the conducting type. The sensors may be fitted into a housing in the floor of a building allowing replacement of the sensors. The sensing station and monitoring station may be connected using a wired or wireless connection and may be powered by battery or mains power. The alarm generated may be a sound alarm 22 or illuminated 21A/C which may also be transmitted remotely. Status alarm 21B optionally indicates a malfunctioning system.

Description

Intellectual Property Office Application No. GB1419558.O RTN4 Date:t9 August 20t5 The following terms are registered trade marks and should be read as such wherever they occur in this document: Celotex Intellectual Property Office is an operating name of the Patent Office www.gov.uk/ipo
I
TITLE: Water Leak Detection System The present invention relates to a water leak detection system, as especially to a system which detects the presence of water or moisture under floors.
Many building have a ground floor formed of a hard core base, a layer of concrete on the hard core, and an insulating layer (e.g. of Celotex) on the concrete layer. A ifirther screed may be placed over the insulating layer or other flooring such as board over which carpet, tiles or floor boards may be placed.
If a water leak should occur either from a leaking pipe or a leaking appliance, such as a washing machine or dishwasher, water will migrate into the void occupied by the insulating layer and can soak into the insulating layer itself. This can excessive cause harm to a building requiring all flooring to be taken up and discarded and often the insulating layer itself.
The invention seeks to provide a solution to this problem.
According to the present invention there is provided a water leak detection system comprising: a) at least one water sensing station adapted to detect water or moisture and adapted to be in the floor of a building, and b) a monitoring station connected to the or each water sensing station adapted to generate an alarm signal when a water sensing station detects water or moisture.
In one embodiment one or more water sensing stations has a single sensing transducer. In another embodiment one or more water sensing stations has a pair of sensing transducers vertically spaced.
The sensing transducers may be conductivity sensors.
The sensing transducers may fit into housing embedded into the floor of a building, allowing the transducers to be located in a desired place, and optionally replaced.
The water sensing stations may be connected to the monitoring by a cable, or by a wireless connection.
The alarm signal may include the generation of an illuminated alarm or a sound alarm, and/or transmitted alarm, e.g. to a smartphone, tablet or computer.
The or each water sensing station and the monitoring station may be mains or battery powered.
The invention also relates to a building incorporating the system as defmed above.
An embodiment of the invention will now be described with reference to the accompanying drawing showing a schematic view of a building with the system of the invention.
Referring to the thawing there is shown a building 1 with a rectangular floor 2 and four side walls 3A,3B,3C,3D.
Floor 2 has a concrete base 2A on hardcore, an insulating layer 211 such as Celotex foam, and a floor covering 2C such as screed or flooring.
A plurality of water sensing stations 10,11,12,13 are provided to detect water or moisture.
Water sensing stations 10 and 12 have two sensing transducers 1 OA, 1 OB and 1 3A, 1311 vertically spaced adapted to sense water or moisture in the concrete base 2A or above the insulating layer 28. The purpose of the upper transducers 1OA,12A is to detect water or moisture before the insulating layer 2B becomes saturated. The lower transducers 1011,1211 detects water or moisture in the concrete layer 2A.
Water sensing stations 11,13 have a single sensing transducer 1 1A,13A.
Each transducer may be a conductivity sensor as is known in the art. The sensing transducers may fit into housing embedded into the floor of a building, allowing the transducers to be located in a desired place, and optionally replaced.
A monitoring station 20 is connected to each water sensing station 10,11,12,13 by hard wires (or a wireless connection) and is adapted to generate an alarm signal when a water sensing station detects water or moisture, The alarm signal may include an illuminated alarm. Station 20 has three lights. A green light 21A, amber light 21B, and red light 21C. Under normal circumstances when no water or moisture is detected by any of the transducers the greenlight will operate. If water or moisture is detected by any of the transducers, the alarm signal generated will illuminate the red light 21C. If there is a malfunction the amber light 21B will illuminate.
In addition or as an alternative to lights 21A,21B,21C, the alarm signal could generate an audible alarm 22, or the alarm signal could be transmitted to a smartphone 23, tablet 24 and/or computer 25 in the same or in a remote location.
Each water sensing station 10,11,12,13 and/or the monitoring station may be mains or battery powered. In this respect amber light 2lB could flash to indicate a low battery.
It is envisage that the monitoring station would have a front panel visible, e.g. on a wall.
An interested party will be made aware at an early stage of any leak created in the building 1, e.g. from a leaking pipe or a leaking appliance, and can take remedial action. The system would be of huge benefit to the house insurance industry with it having the potential to drastically reduce to costs of claims.
It is envisage that a building may have several water sensing station strategically placed around a building base, especially in areas such as bathrooms and kitchens. Single or double sensing transducers can be selected for each sensing station as considered desirable.
The invention may take a form different to that specifically described above.
Further modifications will be apparent to those skilled in the art without departing from the scope of the present invention.
