Hi,
Cheers for your replies guys. I think the floors going to have to come up, don't think I'll get away with an overlay system because of the bi fold doors but not sure? One thing I've just noticed is that they've used Hep2O push fit fittings with Speedfit pipe. I rang John Guest Speedfit and...
Just been up in the loft again and noticed the vent pipe is only about 3 inches from the top of the water level in the F & E tank? A chock of wood had dislodged by one of the rafters causing this to drop down into the tank and stop on the top of the tank. I've pushed the chock of wood back in...
Hi,
I did all of what you mentioned mate, still drawing in air, thanks though. Tank is full when running, I can see air bubbles coming up to the surface & the big vent pipe that goes up over the top of the expansion tank still makes a gurgling sucking sound. If you let the system run a long...
Hi Shaun, I've got pics here of the before the screed went down, just shown them to a plumber friend and he says the pipes are too far apart and as it's a big room ( Open Plan ) they should be spaced much tighter 150mm - 200mm also I read somewhere if they aren't clipped enough the pipes can...
I think they did that, but wasn't there to see it. As you say best to get it done again. Fingers crossed! Many thanks all of you for all your help on this subject, you've been really helpful. All the best!
Cheers guys. That looks like a really good alternative and could save me a great deal of hassle, I'll have a look at that in a bit. I'm thinking.... those pipes going up the wall run from the garage and under the kitchen floor which are now buried below the underfloor heating, insulation and...
Thanks for your replies. Looks like the downstairs floor is going to have to come up again and maybe the ceiling down. Why would you not use push fit on a secondary return? This is all rather worrying as a new build has to have a warranty. If the pipe blew would it cause all sorts of problems...
Hi, Many thanks for your replies. The builders have boxed it all in now. I'm not actually sure if they even insulated them? Are you all basically saying this is a S*** job? This gives me even more reason to panic as they've installed the underfloor heating so it runs under the kitchen units too...
Hi All,
Currently doing a new build that has underfloor heating downstairs and radiators upstairs. From the image provided can anyone tell me in order from left to right what each one of these pipes does by the way the plumber has marked them with tape. Thanks.
Hi,
Just a thought..... if the two pumps are running in tandem and both are on speed 3, should I turn them both down to speed 1. Could it draw air in because the flow rate is too fast, due to the fact that the replacement Grundfos pump is much stronger? The old Grundfos pump was basically...
Hi, It's a Myson controller pump it's got 3 postions on the front, I assume it's like a diverter valve and a pump it's decades old but not sure exactly how it works. I fitted the Grundfos pump myself it's not leaking as far as I'm aware, but I suppose it could be drawing air in, but have done it...
Hi All,
My father has a very old system which I've cleaned and drained. The problem he has is, he keeps having to bleed all the rads every time he uses the heating which is a real pain. Air is being drawn in somewhere but we can't fathom it out. We shall be renewing the system after winter, but...
