such choice - is it just personal preference or are some types more suited than others for certain applications? I have always liked ball valves for their ease and speed of operation, but I need to add/replace some valves and wondered if ball is the way to go here (all 15mm copper pipe)
- Cold feed to boiler (& washing machine) and hot water from boiler to rest of house
- Isolation for outside bib tap
- Sink taps (I assume small "service" valves with a screw rather than a handle - these are small ball valves too arent they?)
Also, does a 15mm end feed elbow add significant restriction to the flow as opposed to a 90deg bent pipe (bearing in mind there is ~10 l/min restriction on the flow anyway in the combi boiler)? I could always reuse the existing bend after cleaning it up but I have no means of bending new pipe at the moment.
cheers
