Mobile Home Plumbing - Which Type of Pipe do I use?

Plumbing a mobile home is not fun: imagine army crawling in a compressed space with nothing over head but
rusty metal and coal black bottom board fabric (or if you are unlucky, wet torn insulation).

Mobile homes are plumbed with a variety of piping from CPVC, Polybutylene ('that gray stuff') and PEX to name a few. We at Ashvillemobilehomes.com suggest PEX pipe for numerous reasons.

Why Pex?

1. It's awesome.When I moved in my current home, the first thing I did was re-plumb the entire home from polybutylene to pex - Best.Decision.Ever. We had a hard freeze a few months later, and my water pipes froze solid (how did this happen? I didn't patch my skirting). After 48 hours of being frozen solid, the weather broke, and my pipes thawed. Only a metal shut off had broken.
2. Easy of use - Pex pipe can be cut with a hacksaw, or a pair of pipe cutters. It is flexible and can easily turn a 90 degree angle without the need for an additional elbow fitting. 
3. No Glue Required - You don't have to worry about your repair men sniffing the pipe glue instead of working. Most PEX fittings are reusable also.
4. Hot and Cold Use - PEX pipe doesn't care. Water is water, and so long as it doesn't undergo a phase change into another state due to temperature (water to steam), PEX will handle the water pressure like a boss.
5. Durability - Pex will not shatter, nor crack like PVC or CPVC nor is it degraded by direct sunlight (I'm looking at you CPVC).

Long story short, use PEX pipe when you can. If you need to transition between CPVC or Polybutylene, use a speed fit.
