Wall with hole   

Hi there, hope everyone is well. I'm looking to buy a property that looks like it needs a bit of work done and not sure how serious it is. I can email pics if it helps.

Its a basement flat of a Georgian terrace and in the light well bit facing the main road, there is a large gap in one of the walls supporting the stairs leading to the raised ground floor flat adjacent to mine. This gap is all the way across the bottom of that wall approx 80 X 35cm where all the render or plaster looks like it has crumbled and there are thick slices of render/ plaster on the floor. Doesn't appear to be an actual wall or broke or stone behind the hole so looks like it's just the plaster or render that has crumbled.. I can't currently access the space to see behind it. Also a couple of long cracks running up the wall. Not sure if this is structural or how easy it is to repair. Really grateful for your thoughts. Thanks.James

Looks like a good job But, Not happy with the ridge.

I can't see what they have done underneath, the lead saddle should be under the ridge tile.

I would have thought they would have repointed the ridge while they were up there.

At the moment it looks like a hole where driving rains can enter.

Glad you got it sorted, these sorts of problems can cause a lot of trouble down the line if you don’t get them fixed.

Don't think it's that easy.  The more area you are insulating the cheaper the materials will get per square foot.  Theres also the saving on heating (and possibly cooling, if you have a/c) that would need factoring in to give a true cost.

Easiest way probably just to get a few quotes

I know it's hard to be specific but can anyone give me some idea how much more expensive it is to have external wall insulation than to have traditional rendering? All other things being equal, like removal of old render, cost of scaffolding to do it, it there any formula I can use to work this out. Like maybe it would 'x' times more expensive per sq metre?

Many thanks

Is it just the mortar, or are there any bricks cracked too?

Do you know how old the house is?

Is that a door/window at the bottom left of the pic?

outside brickwork    

Hi, me and my partner are currently in the process of purchasing our first house, we had a homebuyers report done yesterday and the surveyor brought up some issues surrounding a few cracks in the outside mortar of the house. He said rather unhelpfully that they could be fine but that they could also cause problems in the future and advised us to get them looked at. were on a very tight budget being first time buyers at this current time and we've been quoted £400 for a consultation and a report written to tell us whether its a problem or not. ive attached a photo of what the cracks look like. would anyone be able to tell me whether they look like i should contact a structural engineer and get a report done, or whether you think its nothing to worry about and we should continue as normal. thank you!

Looks like a good job.

Did you do the pressure test at the kitchen sink? which would account for the difference. ( you have a balanced system so the pressure difference should be minimal)

How old are the taps?
Has it always been a pressure system or could the taps be low pressure for an open vented system?

The only thing I can suggest at the moment is to re-charge the cylinder.
The only other mechanical fault is going to be the pressure reducing valve, you can buy new cartridges, but my advice would be to ask the service guy if he is qualified for unvented cylinders and maybe bring the boiler service forward to look at the cylinder at the same time.

Phoned Worcester Bosch and they have said that the boiler pressure is fine. Apparently because it isn't a system or a combi boiler the pressure sensor is essentially not connected so the reading is obsolete.

The boiler is due it's service next month anyway so will ensure then that the engineer is happy with this too.

Results of the water test:

Cold Feed - 33 litres per minute
Hot Feed - 21 litres per minute

A bit far away.

Thinking it would be an idea to phone Worcester about the boiler.

Back to the problem, Can you post a pic showing the right-hand side with as many pipes as possible, special interest in the cold feed to the cylinder and the pressure reducing valve.

Note if you re-charge the cylinder it's likely the pressure relief valve will drip and will probably need replacing.

We need to find out the mains pressure, a call to your water supplier will tell you what it should be (average)

Another job you can do, is fill a bucket with a known volume and time how long it takes, do the hot and cold separately. Ltrs/Mins

I would get the engineer back under warranty. something isn't right that needs fixing although I doubt it really is 370 ish PSI.

The dent looks like some leaned against it when they were working the cupboard, maybe put a pair of steps against it when they fitted the expansion vessel.

Ask the engineer if he is qualified to work on the cylinder, he may have the kit to test the hot and cold pressure as well.

Where are you roughly?

Thanks for your help with this - it is appreciated.

Pressure definitely reads 25.5 bar. The user manual mentions it as 'system pressure'. Manual mentions what to do if the system has low pressure but doesn't say anywhere about the system having pressure which is way too high....! I would have assumed a relief valve would have opened or the boiler would shut down to protect itself if the pressure was actually 25.5 bar wouldn't it?

I've put pictures in below of this and of the dent on the cylinder (after posting though.

Will certainly try recharging the cylinder. Don't have a way of checking the water pressure right now unfortunately but more than happy to purchase something if you think it might help. All I can say just now is that the water pressure for both hot and cold seems quite high all over the house.

Also just stuck a picture of the technical specs of the cylinder if that helps at all.

The post you deleted could be important being an unvented cylinder.

Can you check it isn't 2.55 or anything other than pressure? if not get the installer to check it out under warranty. The boiler pressure should be around 1-1.3bar when cold. if however, it is 25.5 bar the boiler wound be scrap.

The red vessel should be reading 1-1.3bar when cold.

Ok back to the problem, do you know how to re-charge the cylinder? it will be in the manual and quite simple to do. normally you would get a discharge when they lose there charge but may be worth trying.

Have you any way of checking the mains and hot water pressures?

Expansion vessel is red

The reading is 25.5 bar on the boiler......? Never seen this change - can’t be correct surely. Reading above the expansion vessel is 1

Yes, it’s the Greenstar 8000 life system

Only moved in 18 months or so so assuming the system and all taps are the same age -2004. We’ve only changed the boiler (original was a 22kw potterton) was certainly the original.

Can’t see the make of any of the taps but the shower is a sirrus calvus. I’ve changed the washers in this once which improved things but didn’t solve them.

We’ve certainly not replaced the cylinder - only the boiler.  I have just noticed that it says max mains pressure is 16 bar though....!

No discharge from either relief valve.

The expansion vessel is it white or red?

what is the unit for 25.5 it's normal in bars?

Is the boiler the life system?

Is the whole system the same age including the taps etc?

If the taps etc are older, what system was in place prior to the new boiler.

Silly question, what is the make/model of the taps and shower?

Is the cylinder a replacement for an unvented cylinder?

Is there any discharge from the pressure valves Cylinder or boiler?

Thanks for getting back thescruff!

Boiler is a Worcester Bosch Greenstar 8000 35kw (been in less than a year) and the pressure guage reads 25.5 consistently irrespective if it’s working or not.  The other gauge above the expansion vessel which reads about 0.8 bar cold and around 1 bar when the water has been heated. It’s an unvented system.

Cylinder is a mega flow heatrae sadia.

Cheers

If you can access the engineer programming menus, menu 01, set option 4 to ON.  This is "Silent part set, no exit tone on part set".  You can also set menu 02, option 4 to ON if you want a single beep to confirm a successful set when setting silently.

let's start with the boiler,

Standard boilers don't exist, so make and model, please.
Is there a pressure gauge and what does it read before and after the boiler is running?

Cylinder, type please, is it an unvented cylinder, or do you have a storage tank somewhere.

Morning all,

Hopefully someone can help out - fruitless searches trying to identify a tool to help me drain down the radiators without peeing water everwhere!

Moved house recently an the radiator drain cocks throughout the house are unlike any I have seen before! Assuming it needs a specific tool to work it but would love to know if someone has any seen these before / any pointers for me? Pictures below:

Hi gents,

Bit of a strange one... asked a couple of plumbers met with a bit of puzzlement so turning to online and hopeful you guys can help.

We have dripping hot water taps and shower all over the house. Shower is the main problem as it isn’t a small drip. This only seems happens when the boiler kicks in and starts to heat the water - standard boiler with a hot water tank and pressure vessel.

I’ve changed out washers in shower (they are old gummers sirrus valves). Maybe improved slightly but still lots of dripping. Taps drip too so not convinced it’s just an old shower / one tap issue.

I can only imagine the increased pressure when the water gets hot it causing this.

Anyone got any ideas?

Cheers,

Calum
