Description
- The present invention relates to a plumbing tundish, which facilitates removal of discharge, from a pressure relief valve, associated with a fresh water system, to waste whilst eliminating the risk of backflow contamination of the fresh water system
- A tundish is a device that can be used to visualise a fault in for example an unvented domestic hot water storage system or an unvented hot water heater. Such systems are typically supplied with a pressure relief valve (PRV) or temperature relief valve (TRV) to allow them to vent when pressure or temperature within the system reaches a predetermined level.
- When the water within the hot water storage system or water heater is heated, steam is created, which results in increased pressure within the system. At a predetermined pressure, for example 5 bar, the function of the PRV is triggered such that it opens to relieve the pressure within the system. The relief is due to the expulsion of the steam from the system via the PRV. The steam condenses on the end of the PRV and the resulting water drips into a tundish that is connected to the PRV.
- The inlet end of a tundish device is connected to the outlet side of the PRV and any discharge from the PRV drips or flows into the tundish.
- The outlet end of the tundish is arranged to discharge any water to waste. Backflow from waste is prevented by an air gap provided near the top of the tundish; the air gap also assists with visualising any discharge via the PRV.
- It will be appreciated that any backflow is undesirable because the system to which the tundish is connected typically contains fresh, clean water and backflow could contaminate the water being supplied from the tank if not prevented.
- A known tundish incorporates an airgap in the upper portion of the body which allows fluid flow through the tundish but prevents back flow of fluids and additionally incorporates a one-way valve, which is operable to prevent backflow of fluid and of odours from the outlet side of the tundish.

This is particularly important when thetundish 10 is connected to a boiler or hot water system, where it will be appreciated that any discharge may be scalding hot. - Referring to
figures 2, 3a and 3b , thetundish assembly 10 includes anon-return valve 38. In the illustrated example the non-return valve comprises a duck-bill valve, but it will be appreciated that other valve types may be used. - The
non-return valve 38 is mounted within the body of thetundish 10 via theinlet end 26 of thelower connector 16. - In the illustrated example, the
