I have just added a water filter kit which comes with the clamp on pipe piercing adaptor. However I allowed for this when the plumbing was added and as such I have a dedicated 15mm copper feed for the filter. I do not like these clamps and want to connect the system directly to the 15mm pipe. Any suggestions???
Use a 15mm compression to 1/2" BSP female straight adaptor and fit a reducing bush in the 1/2" BSP end. BES do a parallel thread 1/2" to 1/8" brass reducing bush part no. 6619 for 31p or a taper thread version part no. 0787 for £2.77. BB
