Re: [Amel Yacht Owners] Joker Valve

VLADIMIR SONSEV
 

Hi Alan,

I have the same problem and I can't resolve it. All new valves do not close completely. There is 0.01" -0.015" gap between valve lips. I thought that I have a bad batch of valves. I checked valves in the different stors and all of them have a gap. Perhaps under some pressure the valve get closed and on Amel the pressure is not sufficient if holding tank is at low level.
I would like to know if evrybody see a nerrow opening between valve lips on the new valves.

I never really understood why they called it a "Joker" valve, now I think I know: it is a joke, it doesn't work!

I've replaced this valve in both heads twice now and the bowls still slowly fill with backflow from the pipe to the holding tank.

Does anyone have any ideas on how to stop this, or have i just got a bad batch of valves ?

No, Eric.  On Kristy each head has its own through-hull intake in the "hall" outside each head.  The anchor wash gets its intake from the one that feeds the forward head.
In the engine room, the manifold feeds the engines, the A/C cooling pump, and the watetmaker.

Kent,
Do you have a Jabsco electric toilet with the water coming from the manifold via a pump from the engine room? That is how my SM 376 is arranged.

Aha!  I don't have that setup...only one discharge hose that goes to the tank.  So your head has no holding tank?  I didn't know that. Does your aft head have a holding tank?

When I'm going to be at anchor for a while, I flush one head good with bleach water while still at sea, and leave the dump valve open...That's my pee head.  The other head stays closed...that's the poop-only head.  I guess that's how you use yours when at anchor?  Anybody have another system for reducing the frequency of dumping the holding tanks?

Not the intake hose, the exit hose . It may be switched to empty direct from the toilet or a holding tank

Hi Alexandre,
on Super Maramus with
holding tank there is no loop - because the way the hoses
are connected to the tank and the tank/its vent act as a
loop/valve.

I think Ian was may be referring to something else…

I don’t have a siphon loop either.

Hi Alex,Yes those are the joker
valves, I was asking Ian about the anti siphon valves, which
he says are on the intake hose.  I don't have the
siphon loop, but on Kristy the intake (thru-hull) for the
forward head and anchor wash is in the passageway between
the head and the hanging locker.KentSM243Kristy

Good morning Kent,



They are in the restroom.

You might know them as duckbill valve.



Part 12 on the following image

This is not our restroom, but gives you the idea.

Hi Ian.



I'm not familiar with the valves you're
referring

to. Where are they?



Thanks,

Hmm, maybe I misunderstood Ian's reply.  So on some boats there is an anti siphon loop/valve on the output side of the head, too?

Hi Alex,
Yes those are the joker valves, I was asking Ian about the anti siphon valves, which he says are on the intake hose.  I don't have the siphon loop, but on Kristy the intake (thru-hull) for the forward head and anchor wash is in the passageway between the head and the hanging locker.

Good morning Kent,

They are in the restroom.
You might know them as duckbill valve.

Part 12 on the following image
https://www.jabscoshop.com/images/37055exp.jpg

This is not our restroom, but gives you the idea.

Sincerely, Alexandre

Hi Ian.

I'm not familiar with the valves you're referring
to. Where are they?

Thanks,

Re: [Amel Yacht Owners] Re: Joker Valve

karkauai
 

Hmmm.  That's on the intake side, the joker valves being on the output side.  I have a strainer between the stopcock and the pump.  I'll have to look to see if it has a one way valve as well.
Thanks.
I have made a practice of filling the head with fresh water every few months or when ever I  leave the boat for a week or more, and putting some vegetable oil in before flushing it down.  I read somewhere that it helps keep the joker valves supple.  I also ask the crew to flush for a good 10 seconds after using the head to get all debris and urine out of the discharge pipe.  I have to change joker valves about twice a year with this regimen.

On the hose from the sea cock. It is usual to have a loop in the flexible pipe taking it above the heeled water line. There is usually  plastic 'u' bend clamped on to the up and down pipes to form the u shape. This bend should have a small screw cap (like a car tyres valve). Inside is a tiny rubber non return valve. It allows air into the pipework to prevent the motion of the boat pumping sea water back up the pipe until it siphons back into the toilet.

Hi Alexandre,
on Super Maramus with holding tank there is no loop - because the way the hoses are connected to the tank and the tank/its vent act as a loop/valve.

Good morning Kent,

They are in the restroom.
You might know them as duckbill valve.

Part 12 on the following image
https://www.jabscoshop.com/images/37055exp.jpg

This is not our restroom, but gives you the idea.

Sincerely, Alexandre

Hi Ian.

I'm not familiar with the valves you're referring
to. Where are they?

Thanks,

Here's a link to a great article on joker valves in Practical Sailor.

Re: Joker Valve

Ian Park
 

On the hose from the sea cock. It is usual to have a loop in the flexible pipe taking it above the heeled water line. There is usually  plastic 'u' bend clamped on to the up and down pipes to form the u shape. This bend should have a small screw cap (like a car tyres valve). Inside is a tiny rubber non return valve. It allows air into the pipework to prevent the motion of the boat pumping sea water back up the pipe until it siphons back into the toilet.
