Plumbing: PVC vs Hose

[SkullV]

I Prefer to use PVC for everything. I have an oversized pump so a little head loss from 2 90* fittings is not an issue.

I always incorporate a section of SpaFlex into the return portion of the PVC to soak up vibration and allow for a little play when I am removing the pump via the ONE true union incorporated into the pipe.

PVC is more durable than flex hose in my opinion.

Flex hose can get cut, torn, chewed by my dog, etc.

I personally like PVC because of the uniform look and strength. It can't get kinked or loose it's shape. I like things that are stout and hold up for years.

Are you referring to vinyl hose, or flex PVC?, because if you put enough force to kink, tear flex PVC, or chew through it on your rigid plumbing, the rigid would be totally in shambles. I guarantee your dog chewing/pulling on rigid PVC will cause way more damage than flex PVC. Vinyl hose does have drawbacks due to the hose clamps and kinkability, cutablility but flex PVC has none of those issues and is just as durable.

I personally will only use rigid PVC where some rigidity is required like standpipes. Flex PVC reduces vibrations, and allows for some play in removing return pumps etc, but there is nothing wrong with rigid either.

I consider PVC and flexible PVC as one in the same and all other types of hoses as other option. I only use PVC for all my plumbing unless it for testing/short term use.

I recently plumbed a 180. Initially I used all rigid PVC, but it was loud. I was really surprised by how much the water flow echoed, especially for the drain. I ended up using flex PVC (aka SpaFlex at Home Depot) for the drain and the part of the plumbing that connects the to the return pump. The rest of the return plumbing includes some valves for reactors and a tee to the refugium. That part is rigid. This setup is MUCH quieter for me. My experience...
