I need to run a line for a water inlet to a fridge (for Ice/Water).

I have easy access under the house from our water pump (we are on tank water) to the location of the fridge in the kitchen.

The plumbing in the house is Buteline from the pump outwards (it is alkathene from the tank to the pump).

I can either:

a) Install a double tap where I have currently got a single (next to the pump, but under the house in an undeveloped 'basement'/storage area), and run alkathene using Anka joints/bends a short distance into the water filter/pressure reducing valve that came with the fridge (fridge kit contains a 15mm adaptor down to it's PRV then through the filter into the fridge with a 6mm 4m hose). Pretty easy to work with 15mm alkathene and Anka joins.

b0 Get some Buteline and install a 'T' junction before aforementioned tap and install another tap (inline) then to a 15mm screw for the filter kit. I would need to get hold of a Buteline crimping tool though (I don't have one and they are pretty expensive I think).

Which do you think would be better? Does Anka withstand the pressure of a domestic water pump ok? Do places lend out/rent Buteline crimp tools?
