Bulkhead Mounted Gravity Holding Tank

I like the idea of PVC plumbing but would it be difficoult to clean it down the road when the plumbing gets calcified?

Since calcification can be prevented with weekly doses of distilled white vinegar, I'd have to say no.

If, otoh, you're one of those who waits to do anything until the buildup has all but completely blocked the line and then removes the hose to beat hell out of it on the dock and then puts it back, then yes...it would be more difficult to do that to PVC than with hose.

Which proves again that prevention is always cheaper and easier than cure.
