Advice on a bottom drain, false bottom & using a pump

That's not a bad price for a custom false bottom. Especially when you see some of the American ones. NorCal etc. If it does the job and allows you to use your chugger pump it's probably worth it.

I use a domed false bottom in my tun like this.

I'm thinking in a keggle the domed would be even batter as it would fit in the base nicely.

I set the chugged to about 1/4 open initially and open it up a bit once the wort has cleared without it blocking so far. That's with a grist ratio of 3:1.

How quickly do he sparge? I do mine for about 20-30 mins, but it's tricky to go slow.

@Molc in herms as in BM/GF you have a saturated solution from sugars from your grains and so a long sparge is of no real benefit, you just want to rinse last sugars from husk etc. after intial drain I just perform a simple rinse through sprayhead so I am getting everything and do this with pumped volumes from HLT, it takes 3-5 mins depending on batch size.
HB had a clever idea here and that was to overcook your volumes and do no sparge and simply top up with water in boil kettle. I am guessing this would also minimise any potential astringency, and would only cost pennies v's time spent screwing around on a long sparge

On the FB its important that its covers the entire area of the grain sitting above it as say for example a 10inch FB in a 15inch pot would lead to deadspots and channelling.
Even with Herms I stir at least once over the 60 mins and maybe twice if I'm doing a longer 90min mash.

@Shanna you can also try making one of these

So cut the top of the nipple off of the bottom drain in my mash tun so no going back. Have a 2nd candle tray that I am going to convert to a false bottom once I get a stainless steel cutting disk for my angle grinder. Got in touch with home brew hardware to get confirmation of bore size on camlock fittings they sell before pulling the trigger on buying a whole new set of fittings.

Just check to see if your existing tray will work first before you go to the trouble, it has holes as well as slits in pic yeah?

Shanna, I have 4.5" stainless steel 1mm cutting discs if you need one. Got a pack of 10 as it was cheaper than 1 online

For camlocks, brewpi do full bore 1/2" fittings, but they're pricy. Good quality though. If you're ordering from them, let me know, as I need 2 male screw on camlocks for my plate chiller.

Shanna I found this while clearing out my shed if it's any use to you, it's 30cm diameter perforated stainless

All this talk of false bottoms and nipples, thought I had come to the wrong site

Absolutely useful to me. Is it okay for me to PM you to work out payment/collection from you?

No chance as original tray has two 1/2""holes drilled in it.

Yeah plumbing is full of gender specific descriptions e.g. nipples, male, female. No porn here though

Yeah brewpi is great but premium price. Was thinking of either US or EBay China or AliExpress. Whatever I go for I will get in touch before I buy them to give you an option. Thanks for the offer on the blades but I picked up a pair this morning so I don't have to wait.

I got a male camlock from AliExpress and it wasn't compatible with my BrewPi ones. I think the silicon gasket is thicker on the female connectors, which means they don't fit.
