Asked a question about an outside tap a little while ago, and i have decided to fit a proper copper pipe system instead of using one of those tap kits.

It will only be used for my pressure washer really.

Im looking at still using a self cutting valve for the t-piece coming off the mains pipe (due to the placement of the pipes)

Ive seen one that self cuts and allows a 15mm copper pipe to fit straight into it, the only thing is the self cutting valve has what appears to be a 6mm whole in it, so from the 15mm mains it will go through this 6mm hole to the new 15mm outside tap system.

Does anyone know if this will alter the water pressure/flow at all.

it will be fine, the holes in most isolation valves are less than 6mm, as long as its not a run of pipe thats narrow you will be ok

if your that bothered about it only having a small bore, turn the water off and stick a 15mm compression tee in so you dont have to do any soldering

Thats the reason for the self cutting valve, its such an awkward area with little movement on the pipes im not sure i could slide a T-piece on. I just dont want the pressure and flow to change as its for my pressure washer
