Hi Fitting new kitchen sink and taps tomorrow. Current layout of pipes is as the following picture. 2 x 15mm copper pipes connect straight to the existing monobloc tap. The new tap has the following tails, smaller end screws into the tap. All tap connectors I have found already have a big nut on the end. These new tails look to need a tap connector with just a thread and no nut. Thought I could get a couple of washing machine isolater valves like those in the first picture but they are too big, the flexi hose connector is too small. The diameter of the nut on the new flexi hose is approx 22mm. Or, am I missing something? Thank you.
