Standpipe Height

[Khyber]

For anyone who was kept up from their sleep worrying about my alleged ID boiler installation, I have come to put your mind at rest so you can now relax.

The cast Iron Gas pipe in the wall is 22mm in diameter & runs for approximately 6 metres under the floor & in the wall from the mains cast iron feed then my run of 15mm copper with three 90º bends is approximately 1.25 metres in length.

I beleive that falls within the guidelines shown here:

Again, if anyone would like to add their critcism (sorry, comments) please feel free...

Comment would be, that you think you know it all because you have some scraps of information.
Unfortunately you don't know what you don't know about.

Good grief you don't even know what a rodding eye is.

Poking sarcasm at people who know what they're talking about simply because of your continued ignorance, won't get you much assistance, will it?

wtf are you chatting about

Wtf I'm chatting about is you getting some basic guidance up front, to prevent you making the dog's breakfast you have.

The boiler installation will still be inadequate and illegal.


Off you go.

Yes, that's why there's a switched fuse plate above the worktop as you can see in the first pic, the appliance outlet spurs from that & can therefore be isolated above countertop.

Sorry, thought that was for the boiler, also thought I could see two cables going down to the socket. As the photo's not clear, maybe there's only one and the others its shadow.

Still 1 x 13A fused spur = 3 Kw max

Dishwasher 2 Kw + Washing machine 3 Kw = 5Kw

You'll probably not operate them together, but it's not good practice.

Morning,

I see you have given no actual solutions just general abuse to date, I never said I knew it all, plus I beleive you initiated the sarcasm, my thread started perfectly decently with the real intention of listening to what thoughts people had.

I'm willing to listen when someone has constructive criticism to offer, not just pointing a finger & describing things as "dogs dinner" without explaining why. If it's referring to the waste arrangment, that's the whole reason I started this thread as I was unhappy with the design the local plumbing shop offered.

btw, well done for taking my comment regarding your "shed" guide to electrics out of context.

If you feel the installation is still inadeqaute & illegal I'm more than willing to listen to your concise reasons why & take on board what you have to say, there just doesn't seem to be any reason to type abuse whithout provocation.

I spoke to an electrical contractor regarding this, the arrangement does meet the regs and yes you do have a valid point, however generally I wouldn't use the two simultaneously.

Good thought though.

c.22mm. o/d iron pipe is half inch bore ..welcome to the Corgi`s den just change those traps like I said

Ah, yes the wall thickness will be greater then the 0.9mm of copper won't it... Odd though as I just called a local corgi who said the opposite to some of the comments on here that using the cast iron pipe for the 6 metre run then 15mm copper to the boiler would be fine, is he wrong then?

Incidentally regarding the HepV0 traps, isn't part of the job of a conventional trap to hold on to debris from any wash / dishwasher cycle to prevent it from entering the main drain, or is this quantity too small to worry about?

 

[Nige F]

Know nowt about corgi.....and don`t intend to start now no , traps aren`t to catch sediment, only to isolate pipes from drains via the water seal.......very 19th. Century ..........hep valves are 21st. Century

 

[Robster_1981]

Khyber, I wouldn't take too much notice. Like you say, everyone has their own way of doing things, i know nothing of the gas issue tho

Generally i find this sight very useful and helpful, but there is a lot of patronising comments going around!

I asked a simple question about whether to use 10mm cable when installing an elec shower over on the electrics page and was bombarded with people saying i was likely to set fire to my house and end up in jail

Suggest you ask another member of the kennel club that knows what he is talking about.

1/2" steel (it's not cast iron) is undersized by a long way, end of story unless you know different.

And thats before you want a cooker, hob or fire.

howay DIA it was a cash job on a friday night and it looked like cast iron

didnt need any oil on the ratchet

 

[bster]

I'm confused

Ecotec = 24kw = 80ft/hr gas rate.

say the steel run was 12m (6m + fittings) of 20mm steel pipe = 160ft/hr

and 1.5m of 15mm copper plus 3 fittings say 3m of 15mm= 2.9m\hr(around 100ft/hr)

so if the pipe is 20mm nominal does that mean that it is indeed correct?


although I do understand that there may be other appliances connected which would effect the correct pipe sizing and the .

 

[kevplumb]

20 mm outside steel has thicker walls bster

roughly 1/2"" bore

 

[bster]

so 'nominal' means inside diameter (i'm looking at one of thoses nice charts in a book).

 

[kevplumb]

aye steel inside as opposed to copper outside dia 1/2"" steel (or black iron) is roughly the same size as 22mm copper outside

so that bugger s your calcs right up bonny lad
