The opening line may have been wrong, I was just going by the OP's posting stating gauge going to 4 bar, so assumed that was the pressure the safety valve was working at, I don't think that's way of course with that facts known at the time. I have since been educated that's it should only be 3...

Well thanks for posting. Why didn't you explain that in your post instead of trying to say "Disregard". EH? If any mistakes were present, you should have used that opportunity to correct them. Or posted your procedure for the OP to try, or indeed any others who may face a similar problem with...

Replies, that state there may be other causes, but with no pointer TO the other causes, are not helpful for learning what the other causes could be. I didn't think, at the time of the small permeability factor, therefore thanks for mentioning it. It can happen after a few weeks? I wouldn't...

COOL, Thanks for replying folks. servotech - Don't want any gas police knocking on the door. But some basic checks can get problems resolved quickly, or at least give an indication as to repair time and cost. Is this repair in need of a gas safe technician as it's on the water side on the...

Thanks for adding your comment. Where else would the water come from in the "air" side of the tank? I'm asking cause I'm interested. Anyways, I will have to reword my statement then... If there is water coming out of the air valve, it is a possible sign of the diaphragm failure in the...

Oh, I must add... I had a similar problem with my boiler, which was the same make and model..... Although didn't have the circulation problem due to the closed return valve, but as someone earlier pointed out, the valve should be open. My problem involved a rise in pressure during operation...

Ian, Would you care to clarify WHAT, in your opinion is wrong with the statement I made. Or is it that I have gave too much info away? EDIT:- And if the people that thanks and likes the post want to contribute as well, I would be interested in the opinions, and explanations of what is wrong...

The pressure will rise to 4 bar then the safety valve will lift. If you switch the boiler back off the pressure probably comes back down to below 0.5 bar, resulting in a need to top up the pressure again (?) perhaps. Have you tested your expansion tank? From your description it sounds like...

+1 for the sketchup.

How about a "French Cleat" style of mounting? Visible screw head problem solved.

Thickness of ply (or other) would depend upon general arrangement and strength of the frame underneath. Your looking to get a strong, solid surface. Perhaps the people that are fitting these may come in with suggestions. In my project I used 2 layers, but at this moment in time I can't recall...

The rubber glues onto a ply, or similar, surface so thickness isin't as big a concern as it may seem. Any frame has to be covered in the appropriate thickness wood sheet material. Search the forum there are many EPDM v's felt posts. I fitted small scale EPDM covering some years ago (as a test...

I don't think any SLC actually self levels all that well. (but I stand to be corrected if someone knows better :) ) Yes, you will need to give it some assistance when its poured, using a float to push it into corners and generally try to get it reasonably level before it starts to set. As...

Companies gone from everywhere not just Kilmarnock. Grangemouth refinery next? Oh dear.

Or even 50mm in one application (Wickes deep base)
