The uniqueness of the Tuke and Bell designed to Ground Water Relief Valve lies in its flexible sealing faces. These maintain a highly effective seal in the presence of sand and silt. There are no mechanical moving parts requiring the use of guide rods or hinges, so risk of failure due to corrosion is entirely eliminated. The valve element can easily be inspected or replaced ensuring maintenance is kept to a minimum.
The valve has been developed specifically for incorporation in tanks or pools which may be subject to unusual pressures brought about by a rise in the water table while the tank is empty or partly empty.

The diagram illustrates the Ground Water Relief Valve grouted into the base of a tank. The treatment of the ground below the tank depends upon the strata. However it is generally desirable to provide some form of well point below each valve.
It is an advantage to build in the outer valve and then fit the valve and retaining plate on the completion of the tank. Doing so avoids contamination of the rubber seals by the grouting compound.
Ground Water Relief Valve Patent No. 1021.266
The graph provides the flow rate through the valve related to head differential. From this the number of valves required can readily be calculated to suit the conditions on a particular site.
