PVC pipe is just fine! And don't under estimate its strength. 1" schedule 40 PVC has a pressure rating of 450 PSI @ 73.4 F. Many times in the past I have used PVC pipe to add to a pipe wrench for added leverage. I have NEVER broken a piece doing this.
But some caution here.... the fittings such as Y's and elbows are not as strong as the pipe it self. I have used PVC pipe for over 25 years for boat waste lines. First in my older sailboat and now in my powerboat. And my lines are long.
Another caution to consider is with the pipe diameter. Mine are all 1 1/2" schedule 40. If you are flushing
with raw salt water
, there is a risk of building up a salt
like residue inside the pipes that will restrict flow. I add numerous clean outs just in case I have unexpected problems and later I changed both heads to fresh water
flush which I find better than raw salt water
There are several past discussions on PVC here in the forums
. It is great stuff and it does not stink!
