Yes, by taking the draining nut out of the magaclean, I can reduce the pressure. Both E.vessels were checked the last time the sensor went.

the white e.vessel is on top of the hot water cylinder (pic.4). What is above the red one is a plastic food tub. The system works very well normally. It is only when I get this problem, that things go astray. Yes the pressure is released, via the Magnaclean.

Sorry I meant reducing pressure. Top up is by a feed in via flexible hose and 2 taps.

Yes, it was leaking. The little black valve on top was tightened down but it is a new one, as are the 2 others and it does not do it now.

No, the pessure gauge shown is not near the pressure sensor, which when they changed them before, I think were to the left side. The HWF pump seems to be inside, next to the gauge just mentioned. I would need to dismantle the shelf above the E.vessel to get a photo.

3 pressure sensors over a 6 year period. Always the same fault.

Here are some photos as requested. No rads at all, UFH in polypipe throughout.

I only top it up, via the Magnaclean, when I get the F75 message and this has only fixed it the last 2 times (since Feb this year). Before then was about a year ago when I got Vaillent in and they changed the sensor. Just saying that it gets dirty. The last time I had it all flushed through. I...

It is running now and is a 3.0

Yes. It does this as soon as the system fires up. It is an Eco tech 630 and I 'think' it has a pump internally and 2 Grundfos pumps for the ground and 1st floor pipe runs.

Hi. My Vaillant boiler will only run on high pressure above 2.7bar. Anything below that and the dreaded F75 low pressure warning comes up and I have to put more water in till it gets to 2.8. The sensor has been changed at least 3 times on this 6 year old boiler. It runs an underfloor heating...

I have a fairly modern house with underfloor heating throughout. All plastic pipes, no radiators or metal parts, other than the parts in the vaillant ecotec plus 630 boiler. It has a Magnaclean filter fitted, which I check at least twice a year. Every time I do this there is a build up of...

I have a Robbens UFH system, that was fitted in 2003. It has no flow meters but does have blanked off caps on the front of the lower run of the 2 manifolds, one for upstairs, one for down. My questions are. Is there a way to fit flow meters? There seems to be a big build up of air in the top...

I believe they are standard single pole indoor light switches and are switched off at the times of the tripping. Another indoor light switch goes to a pir, which controls 4 lights, which is normally left on. I went out and rattled the 4 lights and the pir but nothing happened. All these lights...
