Hi aĺl nearly finished my keezer. I'm using a flow controller. How much pipe should i use between that and tap? Thanks

What internal diameter is the pipe Graham? That, the serving pressure and temperature the beer is kept at will dictate length.

I use 3/16" and need less than 12" to reduce the pressure sufficiently in my setup.

Don't know internal dimension. Says on the pipe 3/8 inch × 0.265 inch wall .it's John guest fitting. Going to be serving around 10 degrees I think .thanks

 Im not sure what difference the regulator will make.

my flow controller has 3/8" in and 5/16" line out..  the important thing about the flow controllers is too fit them as close to the keg as you can..  then the length of the line is not as important as the controller is reducing the pressure..  i shortened mine so i could clean them with a pipe cleaner and it made little difference..

this vid from kegland explains the theory..  although i use the john guest type its the same thing in practice

Ok. I've got 1 of those stainless controls that fit directly on the Cornelius keg. I was thinking about a meter of line or is that too much? Thanks

Think they might have said feet and meant inches in that calculator Pesh - it's recommending 10 feet of line for my system and I use about 10 inches for a really controlled slow pour.

3/8" line will give you little to no appreciable resistance so I'd go with Alco's info above and try and have the flow control perform all resistance on the setup.

I initially began on 3/8, went to 5/16 and then bought reducers to go to 3/16. I've no flow control though, just straight from the keg to the tap.

Here's a good article from beer Smith which explains the calculations and gives a bit more info.

Looks like I should be using a little more line than I am, but I get good results so won't change the system! 😁

 Yeah summats not right about it 3/8 is longer than 3/16th or im i missing summat ?

Think your right with the line measurement with feet and inches. Said when I calculated around 36 and says feet lol

The narrower the bore the higher the resistance so the less line needed.

3/8 is going to be loooong to get down to where you want. I'd actually considered running a length of it up the garden to a tap at the hot tub but decided the beer would be so warm and foamy on arrival that I'm better braving the cold and going down the steps to get a refill!
