I have always asked myself why the Endex - Yorkshire fittings are so much more expensive than other brands.
For example a pack of 10 Endex 22 x 15mm reducing couplers at Screwfix is £8.81 versus £4.47 for the IBP ones.
I know that Yorkshire copper is good quality, but, why is it so much dearer? and, is it really worth the difference in price?
