head hoses below waterline?

[gettinthere]

I have found nothing that says head hoses like those recomended & sold here are bad for below wateline use. But I don't like to assume anything. The head hoses I have worked with so far are softer than the typical hose I've seen used below waterline. That make me a bit nevrous. I have read that water system hoses are a no-no.

Are head hoses perfectly fine for use below waterline? This would be 1.5" discharge hose plumbed to a seacock.

All sanitation hose is rated for below waterline use

And that includes both of the sanitation hoses sold on this site. In fact, the hose sold here is the most odor resistant hose on the market. Trident is best--and also easier to work with, OdorSafe is next best.

Some clear water system hose IS rated for below-waterline use, but it should not be used anywhere in a sanitation sysem, whether it's rated for below waterline use or not. because it has little or no resistance to odor permeation.

Sanitation hose that's exceptionally soft is rated for below waterline use, but it also has almost no resistance to odor permeation. Unfortunately builders and people who want to pay as little as possible for hose use it anyway because it IS cheap.

ALL connections--above AND below waterline--should be double clamped, with screws on opposite sides of the hose...or at least 90 degrees apart if access makes 180 impossible. And use sanitation hose for both the tank vent line and the head intake line.
