Re: When are vented loops required?

OK. I get it now. Thanks for your patience! One vented loop, coming up!
I was also thinking about a few rigid elbows to make it a neater installation.
Thanks for all your great advice.

Re: When are vented loops required?

OK. So now I am looking for compatible 90 degree elbows at Home Depot and strike out. Oh, I did find some, but I'll bet either they don't fit the Triton 101 1 1/2 hose or won't cement properly. Can someone please advise what to look for and where to look?
I have been through similar problems with my garden's watering system so don't mind showing my ignorance up front.

Re: When are vented loops required?

Here's what you need SeaLand Marine Toilet Systems Product Guide (p35) You'll have to find a Dometic/SeaLand Service Center to buy 'em. However, I THINK you may find that the 385341513 Custom hose adapter may be all you need to make the parts from the big box plumbing department work.

Re: When are vented loops required?

Install a vented loop between the pump and the bowl discharge. Do not intall it between the raw water seacock and head pump, ithe vent does not work in the proper direction. You will have to put your finger ovee the loop vent to pump,water into the bowl!
Also double clamp all hoses below water and shut all seacocks when off the boat.

Install a vented loop between the pump and the bowl discharge.

Since bowl discharges out the hole in the bottom of it, that would be hard to do. I'm pretty sure you meant to say bowl inlet fitting. But that's ok...it's been covered in at least 3 of the previous 47 replies.

Re: When are vented loops required?

Back again...Just received my order of Trident 101 hose and now for the fun of wrestling with this monster. Actually it bends better than I had thought, but some hard elbows will probably still be beneficial. My question for the experts is whether or not some sort of gasket sealant should be used in all the joints. I will, of course, use double hose clamps throughout. If sealant is recommended which one? There are so many. I don't want to make it a permanent connection so 5200 will not be used for sure. Any tips will be greatly appreciated.
Bob

Every elbow you install handicaps your system and is the very source of clogs. Ideally there would be just one short run of hose, with as few bends as possible, with no traps, well-supported, installed dry and double clamped.

Re: When are vented loops required?

No, sealant is not a good idea and it is not needed when you clamp a hose.

Re: When are vented loops required?

OK. Got it. Will try to avoid excess fittings of any kind and will not use sealant.
Good advice. Thanks to HopCar and Terra Nova.

Re: When are vented loops required?

Hello folks. Back again after a three month hiatus while boat was on the hard (another story but not about the toilet). Now I am into the installation process. The Trident hose is very stiff but I am managing so far. Question now is: What material hose should I use for the vented loop I need to install between the toilet pump and bowl? It is "just" raw water and not under a lot of pressure. White would look best since it will be exposed inside the toilet area. Also, are there any preferences to the vented fitting itself? I have only seen black plastic. Could paint it white I suppose.
Comments please!

Shields or Trident #148 flex pvc is ok for this application. As for the vented loop itself, most vendors do seem to show 'em only in black...however I found white 3/4" vented loops at Jamestown Distributors Forespar Marelon Vented Loops The photo is black but you'll find white if you scroll through the box on that page.

Re: When are vented loops required?

As usual Peggie beat me to it!
Trident 148 is a nice white hose and plenty strong for that application.
Trident Vac X.H.D Sanitation Hoses -White Mfg# 148

If you're having trouble with the Trident hose on the discharge side, Buy some Raritan Sani Flex for the parts you need something more flexible.
Raritan SANI-FLEX Odor Shield Hose 1-1/2"

Wouldn't hurt to get a copy of Peggie's book as well.

Re: When are vented loops required?

Thanks to you both Hop Car and Peg Hall. Good advice! I have managed to get the Trident hose connected between the toilet discharge and tank inlet as well as from the tank outlet to the three way valve. I might have trouble with the short line to the deck pump out fitting so appreciate the tip on Raritan Sani-Flex hose. I'll get the main lines installed while waiting for the white vent loop to arrive!
