I just borrowed a Jobo CPA2 from a friend.
Its drain valve/tap is loose.
I removed it and its locking nut and cleaned the area that had a bunch of old silicone glue.

What product should I use to ensure it will not leak when a reinstall?
Is epoxy glue too harsh?

Do you have a place that sells a variety of 'O' rings?

No to the epoxy as you don't want a permaseal on that tap ! If you can't find the right washer/ o ring, I suggest packing material (cord/ rope) that forms a seal when used. Basically it's o ring on a rope (maybe 1/16" diameter or so).

When I repaired mine, I think the original washer was still intact so reused that. Mine has never leaked from the tap but it sits in the sink anyways so no consequences if it did ;)

The original washer as all crinkled.
Jac and Fred, I went after a bag of o-rings I had and maybe I found a replacement, thanks.
I'll give it a try.
I'm worried the tap needs a lot of force to turn to open and close and that will eventually weaken the seal.

ah, my tap also was difficult to open and close. What happened was that the handle was turned too much so I had to take it apart and reseat it properly. Can't recall what I did but it's much better now. Am very tempted to replace it with a proper brass tap that can take a hose fitting, that is also easier to open and close.

My tap is hard to close all the way but it has been like that since new.
The tap used to be available on-line, but looks like they are harder to find now:

not as cheap as the brew tap but this is what I'm thinking of to replace the plastic, tough to turn job.

Omer Hecht at CATLabs has these replacement faucet parts, including the O ring, for $28. He does not list just the O rings among his replacement parts. The faucet on my CPP processor is a bit drippy, but I have a plumber in my home town who probably has every size and type of gasket and O ring that has ever been made, so this thread reminds me to make him a visit.

An o-ring works fine. As for the valve itself, just take it apart and clean it up, then a light coating of silicone faucet lube. Do not use any petroleum based products on plastic parts! Mine works much better now

My drain valve started to drip continually. I replaced it with a couple of plastic parts from Home Depot: the yellow valve from the garden section and a plastic hose thread adapter from the plumbing section. Works a lot better than the original and didn't cost $28.

P.S. Looks like I could spend some time cleaning this area of the Jobo! :-)

Thank you everyone.
I found a bag of o-rings and have found 2 very promissing ones.
I'll try to install the tap next friday.

All went well with the o-ring and I was able to process a bunch of film! thanks!

I put in something like this works great. The original drum tap on my CPP2 was made in the UK, beer making. I use a snap open tap , no question it's either open or closed. And I drain and dry my machine after every use. Clean as a whistle
