Outside Tap

[Spinny]

If I am drilling a hole in the wall for a feed to an outside tap, then should I be angling it downwards slightly as it runs from inside (higher) to outside (lower), so that it could be drained out to stop freezing in winter ?

 

(I have seen these Aquor home hydrant things which look good but they don't do one long enough for a 300mm wall with another 50mm of cladding https://www.aquorwatersystems.com/products/house-hydrant-v2-plus?srsltid=AfmBOoqHW00B92NDZHySy1ad2tzrfjrpZWj39xEvAQj6c5kSpvBN-Cse&variant=42444365955322)

Look for a frosty tap, will fit any width wall, drains to the outside like you describe. 
frosty might be spelt frosti have a google.

That’s a dear outside tap. 
 

I fitted one of these to our retaining wall piped from the garage rather than attached to the house. Bit more industrial looking especially given the 32mm MDPE is just clipped to the wall rather than the clean look you’re going for. I might eventually box it in but probably won’t. It’s frost resistant but I don’t trust any of them even the ones that claim to be frost proof so I shut the water off to it in the winter.

It's hard to understand that there are apparently no WRAS approved frost free taps like the Schell Polar II or Kemper Frosti. 

I'm not from here originally, so I'm used to some different materials, though what could be wrong with products like that?

Backflow protection is included, they provide proper frost protection, make fitting the tap a breeze.

Plasson have an 'arctic' tap that's meant to handle cold weather. I've put in a bunch for temporary water.

I have bought a Kemper Frosti Tap from the German Amazon site. 

(Not fitted yet)

@Russell griffiths and all 

 

So I am cutting my Kemper Frosti tap down to the correct length.

On the instruction leaflet it implies that a black plastic piece can be slid over and down the inner valve rod in order to mark the correct cutting point for the valve rod.

However the black plastic piece does not seem to fit over the rod because the hole in the center is too small to slide over the rod.

 

Anyone else that has fitted a Kemper Frosti had this problem ?

@Nickfromwales one for you.

Fitted a few of these but iirc I had to lengthen them for PH dwellings where the walls were thicker than the tap was long.

 

@Spinny, just put the black bit onto the tap without the bar, to see where it seats. Note the position of the face of the plastic bit.

 

Then put the bar in and put the black bit on the end.

 

Measure the two points, face when planted, and face when out too far, and that's the amount to cut off.

Not sure I follow because the black bit will not fit on the end of the rod and slide down it - as shown in this video...

Yes I can measure the length of the black bit (which is designed to to seat against the outside edge of the tap block), then mark the position of the outside edge of the tap block onto the rod, then measure down the rod by the length of the black bit.

Or I could widen the hole in the black bit so it will fit over the rod.

The measurement option is prone to measurement errors.

It seems odd that they would supply a thing to make sure you can measure the rod length precisely, but then not have it actually fit the rod. The rest of it all seems to go together very well and is carefully engineered. So makes you wonder a lot when something like that just doesn't fit.

There is a small chamfer on the end of the rod which fits the hole in the black bit, but it won't slide down beyond that. You can't achieve what is shown in the inset diagram labelled 3 or on the video.

I notice the valve end is spring loaded, so I suppose there is room for error perhaps, but getting the length spot on presumably maximises the spring compression and the strength of the seal.

Time to push a bit harder?

As long as it still has friction, it'll still function as a marker. It's disposable after that?

@Nickfromwales

Also any other tips from your experience of fitting them, in particular...

(a) Wondering what the main tube is made of. It looks quite thickish and when I ran a junior hacksaw across it (admittedly probably a blunt blade) I couldn't even mark it. Planning to get the plasterer/carpenter guy to machine cut it to the length I mark for me, but not sure what blade it might require.

(b) The instructions show fitting the 90 degree pipe bend fitting onto the inside end before fitting the outside tap end. So do I defo need to do this first - I am guessing maybe trying to tighten the 90 degree fitting would be tricky if done last as the tap end will want to rotate ?

(c) Thinking of using a 90 degree isolating valve on the inside end, and probably another one further along the pipe for ease of access as the inside end will be hidden behind kitchen appliances so rather inaccessible.

(c) Any issues when tightening up the outside against a vertical surface given the tube runs at a slight downward angle ?

It would have to be hammer time.

I think it would be better to drill or twist out the hole very slightly TBH.

What are those German's up to though ?
