What does a tundish look like?

The tundish is a conical-shaped piece of plastic that sits within two pieces of pipe. It contains a clear window that allows you to see into the pipe and look out for any drips that shouldn’t be there. It must be positioned within 600 mm of the PRV in a safe and visible position so that it can be checked.

What is a boiler tundish?

A tundish is a fitting installed on overflow pipes that allows people to see if water is flowing from the pressure release valve. If dripping water is visible in the tundish, a GSR engineer should be called immediately to inspect the boiler.

What does a tundish do plumbing?

A tundish is a fitting installed on pipes to provide an air-gap and catch any drips caused by overflow. This in turn helps prevent unsanitary cross connection, water damage or spillage. However, tundishes are often overlooked as an unnecessary expense by plumbers during bathroom or laundry installation.

Is a tundish essential?

First, and most importantly, it serves to prevent any sort of cross contamination between an overflow pipe and a drain pipe. Without the tundish in place, you would not be able to see any water flowing from the pressure relief valve to the overflow drain.

Why is it called a tundish?

The word tundish originates from a shallow wooden dish with an outlet channel, fitting into the bunghole of a tun or cask and forming a kind of funnel for filling it. These were originally used in brewing.

What is tundish in English?

1 : funnel sense 1a. 2 : a reservoir in the top part of a mold into which molten metal is poured.

Where should a condensate pipe be installed?

Where an installer is fitting a new or replacement boiler, the condensate discharge pipe should be connected to an internal “gravity discharge point” such as an internal soil stack (preferred method), internal kitchen or bathroom waste pipe such as sink, basin, bath or shower waste.

What does it mean if the overflow pipe is dripping?

When an overflow pipe is dripping or running with water, one of the most common causes is a problem with a float valve. This movement turns the cold-water feed on so the tank refills. As the water level rises, the ball rises to switch the water feed off again when the tank is full.

What is a dry trap tundish?

The patented Hotun Hiflo Dry Trap Tundish allows a safe and visible way to discharge from a sealed system boiler, or for an unvented water heater temperature/pressure relief valve (PRV) to be directly connected to an internal waste or soil pipe, meaning foul odours are kept outside in the drain.

Can a tundish be used in a boiler?

I know an unvented cylinder can use a tundish and then into a dry Hepvo trap with no solvent weld joints in the waste pipe. Not 100% sure about a boiler discharge as this will be contaminated as an unvented cylinders discharge will not be. If it is OK use a HepVO trap as no water to dry up and give off drain smells.

Where do you put a tundish in a hot water tank?

However, because the system operates under high pressure, some safety devices are required, including a tundish. A tundish sits on the piping just outside the cylinder near the temperature and pressure relief valve. The pressure relief valve (PRV) will ensure that the pressure inside the tank doesn’t get too high as the hot water goes in.
