What is the level of difficulty for installing plumbing (pvc) lines underneath a mobile home. Seems like to me its just sloping pipes with couplings and adapters.:cool:

PVC is quite DIY friendly. I usually use it for the little projects I do. Make sure you use the primer and cement labeled for use on PVC. Drains do need to have a little slope to them. They must also be vented where the drain turns and goes down after a ''P'' trap. Service lines don't need to slope unless you want to be able to drain the system. Hot water requires the buff colored CPVC. It takes a different primer and cement. For a small job, you could buy one can meant for both.
