Hi, really need some advices here, moved from serious kopitiam

Long story short, immediate double storey house underground pipe leaking. Going to reroute new expose pipe from meter to tangki & kitchen.

- how to deal with ugliness of the black pipe expose on house exterior?
- has a kind person suggests by using PVC trunking/covered with bigger PVC pipe
- i don't want it like hanging a pipe on the roof but well fixed with U clip along the wall
