Best Head Hose

Ours became permeated and was replaced (PVC) at 10 years, but we were beginning to notice it a bit earlier than that. Not full-time use.

I have never had that problem with the proper white sanitation hose (which costs bundles more than the above stuff).

No, I'm talking about Shields Series 148 sanitation hose. Listed here http://www.seastarsolutions.com/wp-c...nal-LowRes.pdf in both sanitation and freshwater application groups.

I wasn't recommending it, just observing that Shields describes it as a possible choice. (For this thread. In my own application, it was for freshwater.)

I had the same experience as colemj once.... bumped the nearly new hose that was on a rigid bronze seacock, and one side split spraying seawater like a shower! I think the problem is expanding it to fit. If it simply slips on it may be OK. But it seems to be made to the small side so that never seems to happen.

It was on a seacock? Would that have essentially made it into a pressurized system?

Heh... I was thinking about the bowl in the head, and the joker valve. Only about a jigger's worth.

I usually have cheap vodka around, so that'd save me buying a full bottle of EG for only this one application.

Yes, that is the same one I was thinking of. I didn't realize that one of its recommended use was for sanitation. I edited my post after I saw that.

It really is about the poorest choice of the sanitation hoses out there. I would be frightened to have it in our sanitation system! If you want to use hose for sanitation, stick with Trident 101, PolyX, Odorsafe and similar. You really do get what you pay for here (PVC/ABS excepted, of course).

Yeah, I was just editing myself, too. Our own use was for freshwater, not sanitation.

???? A jigger is not going to get you any freeze protection. It will make the bugs frow faster... except that the ethanol will evaporate within weeks.

I think you mean ABYC.

Not all sanitation systems are below the waterline.

Not all boats built use ABYC standards guidelines because they are not built in the US.

Nothing is illegal according to ABYC - they are only guidelines, not laws. There is no penalty for not fulfilling them.

Everyone makes rational decisions around if, and how far, to follow ABYC guidelines. For example, the fuse to our house battery bank is 14" away from the battery post. That is ABYC "illegal", but I feel confident it is OK.

That is my question as well, I'm replacing my hose in the near future as the locker my tank is in smells bad, near as I can tell 101 is the hose Peggy recommends?

Now that I have completed the hose replacement my advise is:

Get the most flexible "good" hose!

BTW - it is pretty much a lost cause to get a barbed fitting into Trident 101 unless you can get perfect leverage to force the fitting into it

It was well below the waterline. A lot of pressure really from a hose like that. Take out your depth sender sometime.... you'll get about a foot and a half of large water column! At least it will on a sailboat.

"Now that I have completed the hose replacement my advise is:

Yeah, last time I did a major hose replacement it took a week for my arms and hands to recover!

I replaced all my sanitation pipes a couple years ago with a combination of Trident 101 and PVC. The design goal was that anywhere black water might sit in a pipe use PVC (like below holding tanks) for sure, an also use PVC wherever it was easy. Use the flex pipe where I had to because of awkward routing. I read all the similar threads to this one back then, did my research, exchanged e-mails with Peggy and came up with this. All seems fine.

This is the first time I've seen a warning about using PVC below the water line. I have it on one of my sanitation seacocks (so always pressurized), with flex pipe on the other. Now you have me worrying...

Here's a tip for getting fittings into Trident pipe - use an automotive exhaust pipe expander like this one: Sears.com. It makes all the difference.

Also I found it difficult finding 1.5" PVC to barbed fittings to connect the hard pipe to the Trident hose. Found this site really useful and very fast with delivery: PVC sch40 and sch80 plumbing fittings - PlumbingSupply.com® They also have all sorts of odd angle elbows for tough turns, and the best PVC Y valves I found (and used).
