New Tap Tails Don't Fit Pipes

[Madrab]

As suggested If you have 2 nuts and get some spare copper olives for the ISO valves, then just fit these into the ISO's

if you look at this photo then it looks like the pipe has PTFE tape under the valve. Why?

When an experienced plumber fits new couplers/valves but uses the old nut and olive (saves cutting the plastic) then its prudent to use a wrap or 2 around the old olives, just ensures there's no leaks

Any ideas how to remove this front drawer to make accessing these pipes that bit easier? It's not the lift and pull out type. It seems to be fixed to the runners.

They usually tilt up at the front when fully opened, then you can lift the drawer base off.

It's not on those ikea type wheeled runners. It seems fixed to the runners.

It looks to me like the runner has a lug at the front going into a hole, so lifting it up should clear it.

There are 2 screw holes but no screws have been fitted

OK, I'll check it

Sharp tug upwards and then lift off, can be a faff if one side sticks.

1. Many plumbing fittings (but not pipes!) are still imperial, based round the nominal internal bore of the pipes they were designed to suit.
2. Thus you frequently get 1/2" British Standard Pipe (BSP), 3/4" BSP. You can also get, as you have, a continental manufacturer using 3/8" BSP.
3. The BSP threads come in two flavours, parallel (BSPP) and tapered (BSPT). The parallel threads are usually referred to as "G" something, such as G1/2
4. The easiest solution in your case is to get a pair of adapters, such as Screwfix Item No. 6089R. Fit the plain end into the existing isolation valve and the end of the flexi hose onto the the G3/8 screwed end. Saves changing the isolation valves. You will also need two nuts and olives for the currently open end of the isolation valves. . Easiest way is to buy another isolation valve (e.g. Screwfix Item 65251) and use the nuts and olives from one of them.

I went for this option because I had nuts and olives in a bag of spare parts, so it was the quickest, easiest and cheapest option. Worked a treat and I'm very happy with my new taps.
