I am in the process of redoing the bathroom and wish to remove the existing down lights. My question is can anybody give me some advice on making good the ceiling? The ceiling at present has those lovely swirl patterns :-) Cheers

I am a structural engineer and would agree with comment above. Do not cut out the horizontal ties unless it has been checked out by a SE. Agree also re the floor. Floor loading is 6 times ceiling loading and suitable mods will be required. Steve

To be honest it seems quite a major supporting column this. I would advise get it checked out by a structural engineer. Better to do it before than 3 months down the line when its starting to crack.

Hi I am a structural engineer so this is my field. If we are talking mass concrete unreinforced you should assume a 45 degree spread thru the strip. If the strip is reinforced the load can be spread further. To advise further i would need to know the thickness of the strip and what the...

You need a structural engineer. :-)

Agree totally. These people are not structural engineers and should not be doing things to contradict BR's. Does smack of incompetance.

Ha yeah. What you have seen is a typical 3 pin arch or to a lesser extent a portal frame. Both these are stiffened by the column with the highest stresses at the eaves or connection between rafter and column. Structures such as these can be "pinned" at the apex with no bending at this point...

Firstly I am a qualified structural engineer so I guess am best placed to give you a practical reply. Secondly it makes a big difference where along the span the notch is. At midspan its at its worst location as the timber stresses are at a maximum. Notching towards the support is much...

Thanks My email is [email protected] if anyone has one to mail. Steve.

I see, as I said its been like that some time so prob alot of air in there. Yes I have a vent as you say connected just as you say.

Yeah I have read on here about balancing the system. Somehow think there is more to it. Rads upstairs are very hot (cant hold hand on them for long) downstairs are ok medium heat. Boiler dial is set to '3'

Yeah really easy. I used a mirror and a torch to find the screw holding it on. DONT FORGET TO TURN ELECTRIC OFF BEFORE STARTING. Make a note of all electrical conns before disconnecting so you can connect new head.

When my motor was giving problems I removed the headunit only, took it to plumbimg merchants and bought a new one. I left the actual brass valve insitu.

Cheers again, As you prob know these valves take some turning and have asked the wife and kids and they havent touched it. Pump is very quiet, never been noisy. Poor circulation could be reason for the different temps. Its like a sauna upstairs! Was thinking of fitting TRV's to cool it...

Cheers for quick reply. Ok valve now turned on. Been in house 2 years and I have never touched it so been like that for some time. What kind of problems would that cause? Steve.

Hello there. I am looking at some ch problems I have been having (hot rads upstairs, med hot rads downstairs, one rad downstairs not working etc etc!) Decided to draw up the pipe diagram so i can understand what does what. The small water tank in the loft - there is a 15mm pipe @ btm...
