Pearson 28-1 Toilet

[dadsdream]

I have a Pearson 28-1. The original toilet was taken out and replaced with a portable. I purchased a new marine head and will begin installation soon. Looking for any original diagrams, photos, or info how they were set up in these boats. It appears that the design was holding tank with pump out only. I cannot find an inlet and outlet thru hull fitting/valve. Thanks for the help.

If your boat is an early '80s model,the absence of any head intake thru-hull is an indication that the original toilet and tank may have been a re-circulating system. You definitely don't want to replicate that! It's equally possible that the PO who replaced the toilet with a portapotty had the thru-hulls glassed over.

So what you really need is guidance in how to install the best NEW system for YOUR boat and needs. You'll find all kinds of information on the net if you search for it...starting with the archives for this forum, West Marine's West Advisor, the plumbing and sanitation forum on sailboatowners.com And I'll be glad to help you too.

I have a 28-1.2. The head holding tank is under the forward part of the vberth in the center. The tank only has a deck pump out. The msd has a valve on the bow side of the bulkhead that diverts from the head directly overboard through a port side seacock about a foot up from centerline. Newer boats switched to gravity drain holding tanks I believe, and had all waste run directly to the tank.

I can take photos of my setup but not until next week.

Hiya-been raining the last few days so haven't gotten out there. But will try Sunday. Only home on the weekends so haven't quite gotten the chance yet.

So sorry for the long delay. Weather and work right. Got the sails on today and took some pics. Forgive the interior, needs a vinegar wash down.

In the first pic, you'll see in the top right corner two hoses. The thin one is the holding tank vent hose, the thick one is the deck discharge. Second photo are the inlet hose and discharge hose for the head. They are routed through the cabinetry (pic 3) and then through the bulk head to the the three way valve in pic 4. In pic 4, you can see the direct discharge routed out to the marelon valve shown in pic 5. The holding tank hose runs through the forward bulkhead to the holding tank in pic 6, which is mounted under the vberth. The seacock for the head water inlet is directly under the head hoses in this photo, and is as hard to get a hold of as it is to get a picture of.
