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.
In general, any tundish will accept flow and store a small amount of material, while dispensing material elsewhere, similar to a funnel. In contrast to a funnel, the purpose is generally to regulate flow, and achieve a more steady output with intermittent inputs, and the tundish typically will take on a different shape.
Heatrae sadia megaflo is showing a visible flow through the tundish.
The water is stone cold through the tundish.
Combination valve has already been replaced.
Recharged cyl countless times.
Cheers
Hi, I have had a full CH system installed in my bungalow Baxi Duo-tec Combi 28HE + 7 rads in a day and am concerned that some corners have been cut.
The boiler sits in a cupboard in the centre of the bungalow. A ll pipework runs up to it from under the floor and to my mind is the high point in...
Hi,
I've recently purchased a new property and need to replace the hot water system. The property only has electric and for simplicity I'm thinking of fitting a vented, direct water cylinder.
The overflow pipe on the current system comes through the bathroom wall and terminates just above the...
We recently had a 120 litre Gold unvented cylinder fitted in our first floor airing cupboard. The cylinder's pressure release valve D2 discharge pipe is plastic (originally fitted for the previous twenty year old BoilerMate) and looks about 22mm diameter. There is approx 100mm of vertical...

Just changing an oil boiler on a job and they have just had a megaflow fitted. The installer has put a lever valve in, on the cold in with a tee connected to the discharge below the tundish as a drain off. Is it allowed?
The geberit duofix 111.622.00.1 frame. Anyone know the list of compatible urinals? What is the pipe interrupter?
Also, why are there 2 flush pipes?
Thanks ...... jazz drummers!:confused5:
Hello Everyone,
This has been happening for time now, well, since i bought the flat which was back last month. When ever the cylinder is fired, after around 10mins of boiling, the tun dish frequently drops water in a flow not drops, then later stops. After which, there is no further hot...

This has been puzzling me for ages & now today I have had a call about water coming through a ceiling.
Went to it, not knowing anything about the fairly new house & found a Heatline unvented cylinder with water all over the floor below the tundish.
Was actually the relief valve from the red...
Hello I have water leaking (dripping/pouring) when my boiler heats up my hot water. Over the past few weeks I have heard a popping noise as well - though not necessarily at the same time. I suspect it might have something to do with my expansion vessel. Can anyone help?
Regards, Zoomer.

Hey is it usual for a tun-dish to splash alot of water out when testing the discharge of the pressure or temperature relief on full? There's no problem with the discharge pipe over 300mm before first bend after tun-dish and less than 9 meters in 22mm.
Hello,
This is my first message here and I'd be grateful for any tips or pointers!
A few months ago, my boiler pressure dropped to the point that it cut out until the filling loop was used to re-pressurise it. Someone else did this for me as this is my first home and I had no idea. I...

We had our boiler serviced on friday. The whole system is only a year old. As part of the service the plumber drained and recharged our expansion tank with a foot pump. He did this because bi mentioned the pressure had been slowly dropping on the gauge. Since then the tundish has had a slow drip...

Hi all,
I have a new build home (now just over a year old) the hot water system is an RM Cylinders Homeflow. Two weeks ago I noticed a dripping noise coming from my airing cupboard, upon investigation I found it was a consistent drip through the Tundish (I only discovered this was called a...
Gents, I have a Range Tribune HE Unvented system with a slow discharge into the tundish. I am G3 qualified however not much experience with external expansion vessels as all I have come accross so far have been Bubble top. I reset the TRV and the PRV but still a discharge. 3 options I can think...
Hey I am currently studying for my level 3 at college and learning about unvented hot water systems. I have a question about the cold feed to these cylinders if anyone can help. I know it need a composition valve on it which contains an in-line strainer and pressure reducing valve. And a...
On a condensing boiler is there anything wrong with terminating the copper prv pipe into plastic soil pipe. Both Condensing pipe and PRV have been terminated at nearby soil pipe.
I have fitted an unvented solar cylinder and the posistion of the cold supply pipework is low level...ideal to connect straight into cylinder inlet. however this would obviously mean that i will not be able to tee the expansion discharge into the D1 above the tundish. Is it possible to fit a...
