Hi all,
New to the forum, I like my DIY projects etc and so this leads me to my query. I have a small 5 litre water heater in an out house, this backs onto another room which i wish to plumb a hot supply to as there is a cold only sink in there. The connections on the water heater are threaded and currently has a flexi hose running off this direct to the tap. The flex hose attached to the water heater measures in at 15.32mm internally.

A standard 1/2 inch connector fitting measures at roughly 19mm internally and so to no surprise is does not fit. Any ideas on what connector size i need for this fitting? the plan is to continue the work in 15mm copper from the heater and feed to sinks which are almost back to back, Hope you can help!

Cheers.
 
Could be 5/8 eg euro any chance of a pic ?

Hi Shaun,

failed the first time with a pic, hopefully this attempt works! I think im with you on the measurement size you suggested... which leads me to my next question, where can i get this fitting from? Ive looked for something in this size too but had no joy.

Cheers

You are not getting a correct sizing by measuring inside the nut. Measure the outside of the male part in inches.
 
Hyco is a city plumbing water heater


19mm is 1/2"

I have tried a straight female connector 15mm x 1/2'' and it is too big. If i measure the inside of this 1/2'' connector (which i now know is the wrong way to measure) it measures at 19mm which is a half inch as you suggest, but i need a smaller fitting based on the pic above.

I will try city plumbing in the morning, thanks for your help, much appreciated.

Cheers
 
If the half inch is too big then more than likely 3/8th or 12mm.. take the Flexi to city plumbing.
 
From the photo, it looks like 3/8" BSP nut end, 1/4" BSP male end. Hard to say when you measure it like you are doing and using mm.
