Braided valve hoses question

kkelly77

Hi, I'm new to plumbing so please forgive me if this question is a bit stupid.

I bought some braided hoses with a shut off valve that I want to fit to me taps in the bathroom. The taps are currently attached to 1/2 inch copper pipes. Do I just cut back the copper pipe and attach the braided hose or is there and fitting I need to get for the hose to screw on to with PTFE tape wrapped onto the thread? Thanks,

K.

Just cut the copper, and use the nut and ring to compress. Their should be one at each end? Use some uniwhite (jointing compand) on the ring.

There's a nut and brass ring at one end and a nut and washer at the other.

That can go directly on to the tap thread, if they are single 1/2" fitting. If its an excisting setup, i would be inclined to use the copper thats their, not use flexi's at all, just put half inch penny valve in stead. They are a small fitting that you control using a small slotted screwdriver, are chrome and come various ways, but in this case a nut and ring at both ends. Cost about €3

Sometimes the ring in the hose is more suited to metric. If it were me i change the ring weather it be a half or three quarter,

The hoses are bought already so they need to be used. Plus, I will be taking out the basin and toilet to tile the bathroom floor. As this will raise the height of the basin and toilet when refitted, I will need the extra length of the hoses to compensate.

Joey, should I purchase a specific 1/2" ring then? I asked for hoses to fit 1/2" copper pipe when in the plumbing merchants so I assumed they would give me the right ones.

Yes if it were me i would buy new rings.

The caps on the flexys should be stamped 1/2in. or 15mm, if the're mm. change the caps & cones for a better connection.
Connect tha F.I. end directly to the taps and then cut the copper pipes to the correct length.
If you put a little bit of jointing compound inside the cap it will lube the fittng and keep the flexy from rotating.

They should exchange them for want you want no hassle. Your not giving back a €1000 boiler that you got ordered in.

The height difference will be very small, for just tile and adhesive. Even with a penny valve, you will have to still cut away a small piece of the pipework.
