External tap

Hi

I have an external tap like in the first 4 pictures here:

I would like to replace the tap portion with the tap shown in the 5th picture and here:

Would this work?

as far as i know, you just (turn off the water and) screw one off and screw the other one on?

I’m thinking this is it too. But not sure

Thats really all there is to it but there are three gotchas if you've never done this before. Making the joint watertight, getting it watertight and the tap the right way up and finally tight enough so it doesn't move every time you use it.

Basically just put a decent amount of PTFE tape on the thread and wind it in and stop when it gets really stiff with the tap the right way up or chance it and do another turn? So basically don't worry if you have to fiddle around to get everything lined up, waterproof and good and tight. Take it out try again and use more or less PTFE tape.

Edit: I use several like this outside https://www.amazon.co.uk/HydroSure-Frost-Proof-Bib-Tap/dp/B079J4L2LK/ which are plastic (avaiable in Glambia and builders merchants). Sounds cheap but they are very good quality plastic and haven't split when its been below zero here which the metal quarter turn taps always do. What happens is the water in the ball part of the closed valve freezes expands and splits the tap. Looks fine and doesn't leak till you come to use it next when water pisses out the side of the tap. You've been warned

Before applying any tape/sealer, put the tap on counting the number of turns it takes to to tighten while still ending up with the tap vertical. Then apply about 11 to 12 layers of ptfe (less if using some hemp or compound with it.) Most important thing with such fittings is not to have to turn it back a little, that breaks the seal.

I would prefer to use compound and hemp on such an installation, it gives a better seal while also ending up with a tight tap.

Thanks all. Actually in the end I just did a very basic fix and it resolved the issue (essentially a leak)

However, I may replace the tap with a lever one at some stage, so that is for the tips

Another q. For the future in case of issues and to be prepared.

I think I have identified the tap to turn off the water supply, according to other neighbour, it’s underneath the sink. (Exact same house)


When I turn this off, should water to the taps just stop or does the water still flow through the taps as it’s getting it from the tank in the attic.

why do you want to change?

Looks like you are just missing the screw on bit for your existing tap that will allow you put a quick connect on it

I replaced the external tap with this Brass Tap from cpcireland - great value.

I am sorted now with the tap. All fixed now. Was just a leak.

Above is my new question

The stop cock under your sink shuts off the mains water into the house. Your kitchen tap is fed off the mains and normally the outside tap is connected to this (thats why outdoor taps are usually close to where the kitchen sink is). Shutting off this valve should stop the water for your outside tap.

The best thing to do is turn on your kitchen cold tap, leave it running and close the stop cock. Then go outside and turn on your outdoor tap to make sure there is no water coming out.

generally this tap turns off the supply to the kitchen sink and also to the attic cold tank
Turning it off however means you still have a vessel of water in your tank that will supply all other taps not connected to the mains until the tank empties, the supply pipe for this generally runs from the hand valve under the sink, up the back wall of the house and into the attic around the soffit to supply the tank

During the cold winter in 2010, this pipe on me froze so I lost supply to my tank

thanks, messed around there.


I turned off the stop cock under the sink, --- and the kitchen sink tap still kept running (was testing with cold tap)



didn't get a chance to test with outside tap yet.

thats normally not the case, turning off under the sink usually stops the cold water supply to the kitchen sink tap

Unless your kitchen sink tap is fed from the cold water supply in the attic

Another possibility is that stop cocks under the sink are often very stiff (!) as they're rarely operated, as well as awkward to get to and get a good purchase on, so you may not have turned it off completely.

It should stop the water fully. There is also a stop cock at the water meter at the entrance to your property too. Its a blue handle that you turn clockwise by a quarter turn to shut the water off.

this was relatively easy to twist, no major force.



will try again to check

Under the sink is a mess as it has a water filter also.

See in the pictures there is a brass handle at the bottom which is the one I was playing with earlier that didn’t seem to turn off kitchen tap. Also another little blue lever at the top, not sure what this is for (probably water filter)

Any idea which is which

Looking at that I'd expect that pipe below the brass valve to be the rising main, particularly as it looks to be a flexible black pipe. But it looks a little bit thin or at least not as thick as I'd expect but I'm used to rural plumbing where everything like that is done with half inch heavy gauge black pipe.

Is there a dishwasher or washing machine near the sink?

yep. dishwasher right beside sink



and water filter equipment under sink also

Pipe with blue valve probably feeds the dishwasher.
