Water point fitting sizes.

[johnmck]

Coming down the GU In to Warwick, we tried to top up the water tank at the services top of Hatton. The thread on the tap appears non standard, certainly larger than the normal Hozelock connector we usually use. 

Same below the locks at the Cape of good hope( had a cracking Sunday lunch yesterday).

Is there a new standard, or am I as usual being a little dense?😋

Do you not carry the hozelock threaded adapters for this very reason

Going back to when we had a boat 8 years ago CRT seemed to change to a bigger thread size. No idea why. This was the one on our mooring at Pollington. I thought they had started to change them back but seemingly not.

 

 

 

The change happened at the same time they put the newer stainless steel shrouded water points in.

There are two 'standard' sizes for tap threads.

 

We use a hoselock fitting that fits both sizes.

With the insert in place it fits the (more normal) tap size, but remove the (white) insert and the yellow part fits the larger size.

When the one on our mooring was changed, none of my adaptors would fit. I ended up buying a 'clamp' on fitting and used that instead by not removing the fitted spout pictured below.

Not on our mooring it didnt. See pic. above.

There is also a black adapter if I remember correctly which you appear to be missing

 

Probably find @M_JGis missing the same bit if it did not fit at his mooring

Quite probably correct. I know I only ever had the white and yellow ones and the thread on the tap was certainly one I had never encountered previously anywhere so never ever encountered an issue, until that is they changed the water point on our mooring.

The newer tin taps were fitted with a hose tail from new but if it has been pinched the thread on the tap is bigger than the 3/4" BSP we are used to. I suspect its some foreign metric rubbish they have bought.

Actually there is a third larger size

I do. I think its the case of contract plumbers fitting Bibtaps they carry

I would estimate that the tap has a brass thread of approx 1 inch diameter, far bigger than the standard hozelock adaptor.

Yep, exactly the same.i carry a good supply of various adaptors, but not one to fit these taps. Wondering if anyone local to the area has any idea.

Fosse locks services a bit further  from Leamington, normal service resumes. Tap and adaptor in perfect harmony once again. 

[gatekrash]

ISTR We had that problem last time we were that way,. We carry one of these on the boat connected to a bit of hose with a standard hozelok pushfit on the other end, it'll fit over the widest tap outlet.

Hozelock 1 Inch BSP (33.3 mm) Pro Metal Outdoor Tap (for Larger Taps More Than 33.3 mm Diameter) https://amzn.eu/d/b8S7aIL

 

Ordered one to add to my connector collection!

[davewally]

I had this problsem at the  ape of Good Hope. The water point above the locks is 3/4 bsp and the one below is somewhere between 1 and 3/4 bsp. It is a new bollard (still had its protctive film on the steel) and nobody had a fitting to fit it.

I reported it to CRT in June but have no idea if anything has been done, probably not.

The old Hozelock/Gardena  black adaptor. was for 5/8" BSP, a size that is now only specified in the British Standard for use in mechanical  couplings. It was at one time  commonly used on garden taps but seemed to get replaced by 3/4" at least two or three decades ago, possibly due to fittings being increasingly imported from Europe. My recollection is that the black adaptors stopped being supplied with 3/4" hose fittings at least 20 years ago. I was recently able to donate one that had been kicking around in my garage for some 40 years, to someone who had an old outside tap and couldn't find an adaptor to fit it. 

 

The size between 3/4" and 1" is probably 7/8" BSP, another size that is now  only specified in the British Standard for use on mechanical couplings. 

 

As the mechanical coupling threads are not now used for pipework, you will be very unlikely to find fittings with these threads in your local builders' merchants, other than as a hose coupler.

typo: 3/8 --> 5/8

It is easy to avoid connector problems by having a couple of black builders buckets (you do not have to be black to use these) and a good funnel in the top of the water tank. Could be a road cone in an emergency situation if it is thin enough at the end.

 

Fill bucket, put other bucket under tap, transfer bucket contents to road cone / funnel, repeat.

 

No hose needed, useful exercise and even more importantly you can appreciate just how valuable drinking water is.

 

 

Hoses are the porn of the devil.

 

This fact is amply demonstrated by the fact that if you have an uncontained hose it will end up making an incredibly bad mess within minutes and quite often within seconds. The storage devices developed to deal with this problem are both bulky and planet destroying.

 

Do not use hoses.

The one at Middlewich at the junction was like that

Bloody foreigners, coming over here taking our water point fittings...

[Chris G]

I believe that the metric pipe thread IS BSP!

[jonathanA]

not sure about that I was recently doing to some work with power washers and had to buy an M22 to 1/2BSP adapter and i can tell you they are very similar but definitely not the same !
