Project mash tun [HELP]

[Vindiv8]

The Missus very kindly arrived with this yesterday:

She has spotted something that looks like it will make a fantastic mash tun. The size of the opening is'nt ideal, but I can work round it. The main thing is it is well insulated.

The plan was to remove the tap, fit a ball valve and make a pick up out of copper pipe. But the internal diameter of the inside of the tap fitting is exactly the same as 15mm copper pipe.

tap connection on the outside

Does anyone have any idea how I can fit 15mm copper pipe to the insides of this. Basically I need something that will fit tightly inside a 15mm pipe and seal, that I can then fit my pick up and strainer to.

I really don't fancy drilling more holes in this, and I need a cheap solution, coupled with project boiler and project wort chiller, project AG brewery is getting close to budget :shock:

it looks very similar to my tun

Fitted a ball valve to mine using the existing thread and a little ptfe tape

I use a false bottom made from a picnic plastic plate

 

[Vindiv8]

I haven't checked the tap yet, but I agree I think the ball valve will go straight on, its, the internal gubbins thats the problem, the tap is 3cm from the bottom of the vessel, so I would need to drop a pipe down, otherwise my loss would be horrendous

 

[Sean_Mc]

Thats why I went with a false bottom design, the syphon affect when draining would give minimal lose.

Daabs design false bottom

 

[Vindiv8]

That looks great! I see you have used a hose connector for the pipe, how is that attached, the inside of my vessel is flush with the sides, and that is the problem I am having. I cannot see a way to connect any type of piping to the tap.

Hi Vindiv8,

I think the reason your pictures aren't showing above is because there's something missing of the end of the photo code from picasaweb.
You need to use the direct link between

or just copy the IMG code 'as is' :thumb:

Hope that helps

V

Sorry V, pic is from Daabs site.

I can fit 15mm pipe in mine with the old tap taken out, then just use some ptfe tape on the outside of the pipe to get a snug syphon affect

 

[Vossy1]

No need Sean, I was talking about the pics missing in the first post :thumb:

 

[Vindiv8]

@ Vossey1 Yeah I tried allsorts, direct link

not direct link, but pics wouldn't show, so I posted the link as well. Just tryed a different way on one of the direct links, no joy.

@sean_mc, that's my problem, 15mm pipe won't fit, the bore of the tap is the same as 15mm piping

 

[Sean_Mc]

IMG and /IMG in capitals for me works better sometimes :wha:

Vin got any clear tubing knocking about, just a thought :hmm:

 

[Vindiv8]

Hmmm either it's repaired it's self or a kindly mod has monkeyed with the tags. Now all I need is a solution to my pipes and i am away

 

[Vossy1]

Aleman has, though the links bare no resemblance to yours :lol:
Thanks A :thumb:

 

[Vindiv8]

will have a look see where I went wrong. Cheers Aleman

I think you will will find that the silicon tubing that "vossy" sells is very universal, both in stretching and contracting.
Just a thought for your connection problems.

If it will fit inside a 15mm copper pipe and seal, then I think it will work, Vossy?

You could use a compression coupler, like this
Put a seal between coupler and the back of the tap if needed :thumb:
Your local B&Q or plumbers merchants should have them

Sorry can't see how that will work, there is nothing for it to attach to on the inside, the pipe is flush with the inside of the vessel, you can't remove the current tap connection, it's welded in. What ever I use needs to fit inside 15mm pipe, not outside. Something like tight fitting silicone hose may well do the trick, unless someone else can see a better solution.

Sean, I wouldn't worry about linking to daab's site. It's a good resource, and I host it for him.

 

[Vossy1]

Sorry can't see how that will work,

From your pictures above this the back of the tap, isn't it :hmm:

If so, this screws onto it, the copper pick up tube goes into the compression end, you tighten it up, done.

 

[Vindiv8]

No, that's the outside, with the tap removed, I wish it was that simple. The blurred shot and the one from the top shows the inside. The silicone hose idea might have legs, probably going to get a meter off ebay to try, can't think of another way.
