manifold

Can anybody tell me what make this manifold is?

Hi all. Hope all is well and safe. I need your advice please. I have a Valliant boiler serving the CH and DHW (megaflo). Just recently, we’ve had underfloor heating installed. Before the UFH was installed, the boiler flow temp was set at 65C (it could be adjusted to 75C) using the -/+ buttons...

Hi, Hoping someone can comment on whether what I see happening at my UFH manifold is OK, or whether there is cause for concern. I'm not an expert on underfloor heating, Our system was fitted about 10 years ago and has worked flawlessly with zero issues all this time. As you can hopefully see...

Hi, We currently have a problem with our downstairs underfloor heating. The boiler appears to be working, and the radiators upstairs are emitting heat, but the downstairs underfloor heating is cold. The manifold under the stairs is producing a strange whirring noise from the grey metal...

Background story: About 18 years ago we refurbished 75% of our house and self-installed UHF in that part of the property with the help and advice of a good friend of mine (who is also a Gas Safe registered engineer). At the time we purchased a design and complete kit of parts from a young...

Hi there - I think I have an airlock in my UFH, and I need to flush the system to get it out. I've watched countless videos on how to do it which seems relatively straightforward, but what I can't figure out is the drain/return ports. They don't seem to have any valves to open/close them, which...

Hello again. I'm moving forward with my new-build project on, I need to plumb my 3 wet rooms up stairs, a downstairs loo and kitchen/utility. Due to lack of availability of a decent local plumber I'm doing the work myself. I wanted to use manifolds for hot and cold supplies. 22mm to feed the...

Hi - I little insight and guidance would be much appreciated. My wet UFH was installed over a year ago by a qualified heating engineer, he went through all stages and did the pressure test as well, everything has been working nicely without any issues. Now here is the unlucky coincidence - I had...

My underfloor heating has sprung a leak where one of the pipes reaches the manifold. I have tried giving it a bit of a clean and tightening it, but to no avail. Every time I re-pressurise the system is goes again. Is it as simple as shutting off the water supply to the heating and replacing the...

Does a Worcester 28CDi Combi have to be taken off the wall to change the plastic return manifold?

Hi all, I have an lpg setup that was fitted November 2018. We have 4 x 47kg cylinders connected to a continental rf6030 auto changeover manifold. This evening I swapped over a pigtail on one of our reserve cylinders that had been damaged by a rat having a midnight feast on it. When I undid...

Is it acceptable to have plastic pipe going into the manifold at such angles as shown in photo? There is definitely stress on the fittings as the pipe is pulling hard to one side on numerous connections. The manifold does not leak under pressure test. Should it be kept as is if it does not leak...

Hello all, my wife and I have recently purchased a house in Edinburgh (move in date 6th dec hopefully) and I have been working hard to get a plan done for a diy manifold and I shall do a complete refit of the bathroom. I plan to do it all myself bar the electrics and boiler connections. The...

Hi thanks for any advice in advance, I've been asked to look at a leaking manifold the general condition of the valves/actuators is poor and it seems logical to replace the whole thing. My question is there any or many reasons they cant be fitted upside down ? I.e cold at the top hot at the...

Hi all. I have a dodgy manifold and I need to replace it. my question is does water flow through the 22mm pipe where my finger is pointing or is there like a block inside the pipe to stop the flow and return mixing in the 22mm pipe? All help is appreciated

Having a load of work done at the moment, part of which is to have wet UFH installed, just looking for any thoughts around the best system to use. There seems to be lots of choice, looking for 3/4 zone system. Any thoughts greatly appreciated.

I need to fit another rad and have spare outlets on the manifold. This manifold is now obsolete. Standard 8mm olives do not fit. I have found Legris brass compression olives at RS online which i would describe as a collared olive. Would these be suitable? Mytub.co.uk shows an illustration of the...

Hey guys Where is the best place to have my manifold? I want 3 zones. The kitchen is 2.4 x 3.1 m The bathroom is 3.1 x 3.1 m (Directly above the kitchen) The conservatory is 2.1 x 3.1m (Directly next to the kitchen boiler wall) The kitchen is the natural choice as all 3 zones are nearby, and...

Hi I'm I've just joined and hope to gain some well needed knowledge! I'm replacing the old 1 pipe heating system in my house as its very old and full of leaks! We're putting down a solid wood floor so I don't want any joints under it that might fail! I'm thinking of using the Emmeti manifold...

Hi all, first post here so be gentle! We have recently installed UFH in around 60M2 of our house. It is a John Guest 3 port manifold assembly with 3 speed John Guest pump & Blending Valve. Each port has an electronic actuator head fitted. The boiler has recently moved into the loft and is a...
