This doesn't make sense

We had a fouled discharge line and while dealing with it, what I saw made no sense too me.

First the sani line from the head is Trident radiator hose , but it is rated to 250 deg F, so that's a good thing

But anywho, from the head the line sweep up to the vent loop, then down about 8" to a Y, one goes OB, the other to holding, about 3' pass the Y ( under the lav ) in the line to holding tank is a gate valve, which was the source of the blockage.

This has never made sense to me, and I'm not sure what the PO was thinking. It would makes more sense to have a deverter Y 8" below the vent loop than it does to have a open Y; because when waste is directed to the holding, it seems to me the OB line is full of waste and the same goes for when the waste is deverted OB there's waste in the holding line up to the gate valve.

So, does this make sense to anyone, if so explain why, I have to change the line out anyhow and if I can find a deverter type Y valve I'll make the change there also


Oh, also,I can't find a Y type deverter type valve, any clues where to look ???

Bought mine at WM...and I agree...there should be a means to shut one or the other off and not rely on just an air lock from the deck fitting to keep sewage out of the pump out line. Dont quit understand the need for a gate valve on the tank either..

With 1"1/4 barbs of course..

I just bought this Jabsco Y Valve from WholesaleMarine.com




The literature says:
Quote:
This Jabsco Y-Valve allows waste to be pumped overboard or into a holding tank. Can be padlocked (not included) so waste can only go into holding tank to comply with USCG regulations. Connections for both 1" and 1 1/2" ports. Dimensions are 7 5/8"L x 7 1/4"W x 4 5/8"H.
If you do need a better vented loop, try this.

Still, Chicago, thank you both; I'm going to get that Jabsco Y-valve,that makes sense.

The vent loop looks like a plastic version of the bronze vent loop I have now
