» Aqua Check:

The Aqua Check is an “in-pipe” mains powered flood check protector designed to monitor complete apartments or houses, or individual showers, kitchens, basements, etc. The Aqua Check System continually checks the water usage by monitoring how long water has been flowing (time) and how much water has been flowing (litres/gallons). If either adjustable setting is breached, the valve will automatically shut the water supply preventing further damage. As the monitoring is continuous, the Aqua Check will know and automatically shut the water supply if no water is used for 24 hours indicating that the premises have been vacated. This feature also enables manual closing of the valve so that the water can be switched on and off by a flick of a switch when entering or leaving the premises. As further protection, the Aqua Check also monitors the temperature of the local ambient air and shuts the valve as the air is approaching freezing to protect flooding from burst pipes should they become frozen.

A typical location for the Aqua Check would normally be just after the main incoming manual water stopcock. The unit is designed for either 15mm or 1/2" pipes but can be fitted with reducers to suit 22mm pipework. Low voltage power is provided from a plug-in standard mains adaptor. The fitting of the Aqua Check is also very simple involving cutting out the length of pipe to the size of the module and slide fitting the module into the gap in the pipe. No spanners or soldering is required. Setting up of the Aqua Check is automatic and any adjustments are very simple. The facia display is fitted with five LED lights, two adjusters and a Reset Button. As a 'flood protector', the system will ignore dripping taps and minor seepage under 0.5 l/m and comes factory set. The system allows 10 litres per minute to flow through the module for a maximum of 10 seconds. This would normally be adequate for standard domestic water usage, but the “Adjust Excess” pot can trimmed to suit (10 – 40 l/min). Water flow is set for for 15 minutes at normal pressures but can be trimmed to suit (10 – 40 minutes).

The water flow time-out facility is provided with a sounder which provides an audible warning two minutes before the water is shut off. If the offending tap is turned off before time-out, the system will automatically reset to zero allowing prolonged water usage (washing car, filling pool etc). Alternatively the Aqua Check can be switched off with the valve in open position allowing unlimited water usage. The Aqua Check should not however be used in areas protected by automatic water based fire extinguishing sprinkler systems, or in other areas with critical water demands.
