Fitting an outside tap.....

These diy kits are ok, but a couple of things you should watch for, the connecting pipe is only rubber (goes through the wall) and could easily chafe and break with vibration if positioned wrongly, and the tap which is designed to fit onto the pipework and then puncture a hole into the cold water supply pipe, could cut a complete piece of copper out of the supply pipe, given the pressure of cold water supply, I would not want a small piece of copper loose in the water supply, it could finish up in all manner of places. The large drill you need to get through the wall is 16mm, and this is only if you do not want to put a protective sleeve on the pipe.
 
ISTR that the double check valve taps are not to current regs & that the non return valve needs to be inside the property, whereas the tap is outside.

Are you even allowed to alter the plumbing in your house?

With consent, yes

I can do pretty much anything so long as I have their authorisation, but on the other side, thy can request that anything I have done in the house (be it fitting a shower, new fire etc) be returned to its original state (when I moved in)

They have some in Wilkinsons, but watch it, I noticed some of one type, the sealing washers had fallen out, try using one without the washer, and you will have a new shower installed.

Retlaw.
 
I have looked into it & the reason you cannot legally use the bib taps (the ones with the valves in) is because they get subjected to freezing weather & are not reliable then, so regs require a separate check valve inside the property.

The little things we learn eh, now if only they made the water regs freely available then lots of us that DIY would be able to do it to the appropriate regs.

Ditto for BS7671 & electrics.

When attaching a quick fitting that screw down into your pipe, it is not a good idea to put it on a main supply pipe to other things like upstairs showers etc.
What your doing is pitting an 8mm diameter shaft into the 15mm pipe, so that can also restrict flow to other stuff depending how far it goes in. put it into an offshoot from the main pipe, I.E. the one to the kitchen tap etc.
 
I don't have any type of check valve on either of my taps, one outside and one in the garage.

When did the regulation come into force and is it retrospective?
 
Yours would just be 'not to current standards' Neil, and I'm fairly confident you know what that means, if you are fitting a double check valve in your own home, you can put it where you like, the idea is to stop water siphoning back out of hose pipes etc, into the drinking water.
As for not interrupting a mains flow to an outlet, that is what you would be doing if you put one of the screw in contraptions before the tap, in fact, put it anywhere in the cold water pipe, and it will restrict the flow to something, it is unnavoidable.

But does it have to be to current standards? That is why I asked if it was a retrospective regulation. My back boiler does not meet current standards for efficiency but I don't have to change it.
 
No you dont have to change it, unless you change the tap, or the pipework, same with the back boiler, you can repair it, but cant replace it unless you meet the strict criteria for not having a condensing boiler, you can still buy a back boiler unit though!!
 
Out of interest what is the criteria for not having one of those expensive condensing things that they lie about the efficiency of? :D:D
 
They dont lie about the efficiency, I have a gas analiser, and can prove that some of these are up to 98% efficient in the winter.. sedbuk is a seasonal efficiency, not a constant... The criteria, in short, is that the savings made would be far less than the costs of installation, or if a condensing flue or drain cannot possibly be installed, this has to be applied for with the council, and very few are successful, if you live 20 storeys up, with no outside wall, you might just get away with it! :rolleyes:

Dont buy the one in the link though, it is one of the older ones (401), there wont be many parts available for that, but plenty for the 502, 57/4 and the likes. ;)

LOL, I was surprised how many parts were for sale for them on ebay.

Anyway it depends who you know that work at Baxi, and I know quite a few :D
 
Well, as this thread has wandered off the edge of the planet, might as well carry on (sorry Emzy), I dont know anyone at Baxi, Valor, Potterton, Main, or whoever actually owns it now, I do know that people who work there, dont used thier products, especially if they have to pay! :rolleyes:, used to be a lot of free stuff about, but I think somebody remembered to close the back door!
