Hi all,

I've been reading this forum for a while, but now I have a question, or rather a request for an explanation, if someone would be so kind. I know nothing about plumbing other than what I've learnt from reading this site, so please bear with me a little.


Brief history: I moved into a new house this time last year and in the summer of last year had a plumber do some of work including; getting rid of the old hot and cold water tank and replace it with a mains pressure hot water system and swapping out a couple of radiators. During this work, I'm pretty sure a (new) F&E tank for the central heating appeared in the loft (I hadn't noticed it previously), or at least the pipe work running to the F&E tank was replaced.

Since the winter's arrived and the heating's been turned on, all three radiators upstairs and one of the two downstairs radiators have needed bleeding every a week, so I asked the plumber back today, and he's cut and capped the vent pipe to the F&E tank.

My wife dealt with him leaving and I didn't get to see what he did, or ask for an explanation at the time. From what I've read on here and else where I'm now really worried that there will be a pressure build up in the central heating system.

Here's what the F&E tank looks like now:https://www.dropbox.com/s/vlq7bv5ux41v728/F&E tank.jpg?dl=0
-The copper pipe used to go into the F&E tank (the vent pipe I believe it's called)
-The plastic pipe on the wall is the mains water inlet
-The copper and plastic is into the heating
-The white plastic is the overflow

And just for completion, the other pipework:https://www.dropbox.com/s/cblmjdyzwqnb6zg/Other pipework.jpg?dl=0

I don't like having to judge and second guess a professionals work, but at the same time I would be really grateful for a second opinion to put my mine at ease.

Thanks in advance
 
Looks like a few mistakes on the UV also.
No tundish on the combinbed t&p valve. No 2 port zone valve connected to the uv primaries.
The combination valve doesn't look quite right either. This guy seems to like capping things off.

What make aand model is that unvented cylinder?
 
Seems that you have had your open vented hot water system converted to unvented. But the heating system is still open vented. Not enough pictures to be positive. But If my assumption is correct. Capping off the vent pipe to the fande tank is plain stupid! However it seems the feed pipe doesn't have an isolation valve on it. So it would be unlikely to blow up.

But still. If what I am seeing is right. Your plumber needs a stern talking to! And also re educating :wink: by the looks of it. Your system is just one cap from a potentially lethal situation.
 
Your plumber has made it a combined feed and vent but the minimum pipe size should be 22mm, he would have been better off leaving the vent and teeing the feed into it.
 
Guessing it is an Albion cylinder. . Combination valve is technically fine apart from the lack of Tundish.


If I was paying for that I would be incredibly pished off.
 
If he had fitted the feed and vent correctly in the first place he wouldn't have needed to cap the vent pipe.
 
As it in the loft, no insulation on pipes either, especially the discharge pipe, which if it's frozen ( letting by on PRV / TRV ).

I'll be more happier if the 22mm speedfit cap is changed to brass cap.
