I am going to install a new head, with a Purasan treatment unit. (Jeff, I know it’s expensive but there are few pump outs around us).

http://www.raritaneng.co..._treatment/purasan.html

Does anyone have a Head discharge thru hull?

If so where is it located?

I am concerned about putting it in the bow area. I am worried about when on plane water being forced back in to the waste system.

I hope that's legal! My old setup (removed) had the discharge about a foot above the waterline, and just forward of the head. Some would say "Just install a check valve.." but I wouldn't trust it to close reliably.

In my 37 there is an 1 1/2 inch through hull for overboard discharge on the port side up in the bow, about 3 inches above the keel. It is actually the furthest forward fitting on the boat. Basically under the V-berth. I never had a problem with water being forced back in that I know of but never really thought about it till now.

Maybe you could put a check valve in that line but I would suggest calling the manufacturers support line and see what they say...Good Luck!

My 32' Sedan has two fittings on the Starboard deck next to the V-Berth/Head wall. The overboard discharge fitting has been permanently sealed, the other of course, is for pumpout.

Below is an attachment from a BoatUS article regarding overboard discharge. You can find this from numerous sources. Plain and simple, NO overboard discharge on inland or coastal waterways, treated or not, period.

We had two separate incidents recently here in Northern Virginia in which someone dumped (probably a porta-pottie) into a local creek and they had hazmats units trying to track the source. Since it was winter, I'm assuming it was an RV'er, but they'd better hope they left no trail behind. They probably would would have gotten away "clean" if it weren't for the blue treatment chemical in the waste water!

Although you are allowed to still have a 'Y' fitting as long as it is locked, why go through the expense, since it would be grossly inappropriate to ever use it even if you thought you could get away with it.

Federal law says that untreated sewage (even if it's been dosed with a deodorant product) can NOT be discharged in inland or coastal waters. This means the sewage from a portable toilet or a Type III holding tank can not be discharged unless you are in the ocean more than 3 miles offshore.

Federal law also states that if you have a holding tank with a "Y" valve allowing direct overboard discharge of untreated waste, it must be secured in the closed position while operating in all inland and coastal waters. Using a non-releasable wire tie, padlock, or removing the valve handle is considered adequate securing of the device.

Almost every houseboat manufactured in southern Kentucky has overboard discharge of treated waste from and MSD type II treatment system. My understanding was MSD type II devices were approved?

In the Ohio River Type 1 MSD is legal.

http://www.raritaneng.co..._treatment/purasan.html

Q1. Is the PuraSan legal to use?

Yes. It is a U.S. Coast Guard certified Type I system that may be used only in conjunction with Raritan Atlantes, Crown Head II and Crown Head marine toilets in areas other than federally-designated no-discharge areas. Type I systems are permitted on uninspected vessels less than 65 feet.

My personal opinion is lets clean up the largest polluters first. I know the local town / city combined sewer systems put out more raw sewage in an hour than every boat on the river can in a lifetime.

Was it above or below the water line?

Mine is in the same area, above the w'line. The fewer openings below the line the better.
BTW, whattzit cost?

ABOVE the waterline. Don't tempt fate and put it below. If a clamped hose falls off (or etc.) you'll sink.

Jeff

PS: Damn few bilge pumps can keep up with a 1 1/2 " hole--and then only if the batteries are still good.

If you are looking for one of the purosan systems I have a brand new one complete with feed unit. Still in the box for $275 plus freight. Am getting ready to list on ebay. I just never got around to installing and my marina put in a new pump out and figure it is just sitting. They sell for almost a grand now The picture of the purosan unit is the exact type I am selling.

Agree that the discharge should be above the waterline. But you need a raw water intake or are you plumbing the head from your freshwater system? Or do you already have an intake? (My unit is plumbed from the freshwater system.) I ask because I'm thinking about the same thing. My research indicated Type IIs are okay on the Ohio and YES municipalities dump raw sewage all the time! That's why we don't have much use for swim platforms on the Ohio. . .

I am interested. It is a purosan not an electrasan?

My discharge on a '69' 28' is on the port side just as you step down into the V-berth. It is about 2/3 the way from keel to port side where the v-berth frames attach. There is a 14" stand pipe that brings it above the waterline. On the outside there is a 1" tall, 3" wide ramp BEFORE the thru-hull hole to prevent back wash.

I have found a holding tank from Ronco (B431) it holds 35 gallons and fits snuggly between v-berth frames 1 & 2. Have to decide where to have the holes will go yet but the time has come!

35 gallons is outstanding. Mine is only 18--not enough.
