Mash Tun
10G → 50GRecirculation-ready mash vessel with false bottom and reinforced base plate. Hinged grain access door standard on 15G, 20G, 30G, and 50G builds for fast, safe grain-out without lifting a hot grain basket.
Heavy-duty 304 stainless brew kettles with a true welded 1.5" tri-clamp bottom drain — not a side port, not a threaded fitting, not a compromise. Built for electric brewing, fully tri-clamp, sized from 10G homebrew through 50G pilot. Three dedicated vessels: Mash Tun, Boil Kettle, and Hot Liquor Tank. Buy one, two, or all three — they share fittings and stack into a complete HERMS / RIMS hot side.
Most "premium" brew kettles use a side port and ask you to tilt the kettle to finish a transfer. The DrainPro doesn't — the 1.5" tri-clamp drain is welded into the bottom plate, the floor slopes to it, and the kettle empties completely with the vessel sitting level on its stand. No tilting, no trapped trub, no dead zones, no threaded leak points.
Not a side port. Not a threaded fitting. A fully welded TC ferrule pressed into the bottom plate of the kettle, so the floor slopes to a single sanitary drain that you clamp a butterfly valve to. Complete emptying with no tilting; CIP cycles run start-to-finish through the same port.
Every port — element, recirculation, sight glass, sample, lid, drain — is welded 1.5" tri-clamp. No NPT threads, no Teflon tape, no bacteria traps. Standard sanitary tri-clamp consumables; valve service with a 9/16" wrench.
1.5" TC recirculation port standard on every vessel; element port on the HLT and boil kettle. ULWD elements drop in; pumps clamp on. No drilled holes, no aftermarket adapters — the kettle ships ready for closed-loop electric process control.
Welded tri-clamp port in the lid for a spray ball or steam condenser. Clean caustic + acid + rinse without removing the lid; condense boil steam if you're brewing indoors. The kettle is designed to be cleaned, not just brewed in.
Each DrainPro is a standalone vessel — use it as a replacement kettle for an existing brewhouse, a dedicated mash tun for a HERMS rebuild, or the heart of a new pilot system. They share fittings and stack into a complete electric brewery when you're ready.
Buy them à la carte to replace tired side-drain kettles, or stack all three for a complete HERMS / RIMS hot side. The bottom drain, tri-clamp port layout, and 304 stainless build are constant across the line; what changes is which port goes where and whether you've got a false bottom for grain.
Recirculation-ready mash vessel with false bottom and reinforced base plate. Hinged grain access door standard on 15G, 20G, 30G, and 50G builds for fast, safe grain-out without lifting a hot grain basket.
Heavy-walled boil vessel sized for electric ULWD elements. 1.5" TC element port, recirculation port for whirlpool, and the bottom drain that pulls a clean wort transfer straight off the hops without a side-port pickup tube.
Strike and sparge water vessel. Heats strike water on a TC element, feeds the mash tun through the recirculation port, holds sparge water at temperature for the back half of brew day. Same bottom drain pulls a final clean rinse.
Welded 1.5" TC ferrule in the bottom plate, sloped floor, butterfly valve clamps right on. Empty the kettle without lifting it, without a pickup tube, without a side-port elbow that traps half a gallon of wort.
Lid TC port for a spray ball; bottom drain returns to a CIP pump. Caustic + acid + rinse in a 90-minute cycle. No tilting to drain rinse water, no rags to wipe down dead zones.
Every port is welded sanitary tri-clamp. No threads, no Teflon tape, no NPT-to-TC adapters cluttering a parts bin. Standard sanitary consumables; nothing about owning a DrainPro means waiting on a single-supplier part.
Thick-walled 304 stainless, fully TIG-welded, reinforced bottom plate. Stable on the stand under a 30-gallon mash; doesn't oil-can when a 5,500W element pulls full duty.
15G, 20G, 30G, and 50G mash tuns ship with a hinged grain access door. Spent grain shovels out the side instead of you wrestling a 60-pound grain basket out of a hot vessel.
Each vessel is standalone. Drop one into an existing brewhouse to replace a tired side-drain kettle, or pick up all three over time and stack them into a complete HERMS hot side — they share fittings and dimensions across the line.
Most "premium" homebrew kettles use a side-mounted ball valve with an internal pickup tube. The DrainPro replaces that whole apparatus with a single welded drain in the bottom of the vessel. Here's what changes.

No. Every price on this site includes free continental US shipping, and we prepay all duties, tariffs, and brokerage on your behalf. You won't get a courier collect-on-delivery for surprise import fees days after your order lands. The price you see is what you pay. (Alaska, Hawaii, and international freight — contact us for a quote.)
No. The 1.5" tri-clamp ferrule is fully welded into the bottom plate of the kettle — there are no threaded leak points. You clamp a sanitary butterfly valve to the ferrule with a TC clamp + gasket; that's the only seal in the drain path, and replacement gaskets are off-the-shelf if you ever need them.
Yes — Boil Kettles and HLTs both ship with a 1.5" TC element port on the side of the vessel, sized for any standard ULWD tri-clamp element. Drop the element in, clamp it down, plug the controller in. No drilling, no threaded adapters, no aftermarket parts.
Most brewers start with a Mash Tun + Boil Kettle pair — that's the minimum for a recirculating BIAB or eBIAB setup. Add the HLT when you're ready to run a full 3-vessel HERMS / RIMS with a dedicated strike-water vessel. All three share the same fittings; you can stage the purchase over months without ending up with mismatched hardware.
Most Spike and Ss BrewTech kettles use a side-drain ball valve with an internal pickup tube — that's the entire argument for the DrainPro. Three specifics worth knowing:
(1) Bottom-drain comparison. Spike does sell a bottom-drain kettle. Theirs uses a tri-clamped ferrule (removable, with a gasket seam) rather than a fully welded one — and the equivalent size lists at roughly 35% more than the DrainPro. Same idea, more money, one more gasket to manage.
(2) CIP-capable lid. The DrainPro ships with a welded tri-clamp port in the lid for a spray ball or steam condenser. Neither Spike nor Ss BrewTech includes one as standard — you'd add an aftermarket weld-in port or skip closed-loop CIP entirely.
(3) Build. 304 stainless, mirror polished inside and out, thickest walls in the industry (1.2 mm on 10G/15G/20G, 1.5 mm on 30G/50G). Heavy enough that the kettle doesn't oil-can on a full element duty cycle.
Absolutely. The lid ships with a welded tri-clamp port for a spray ball; the bottom drain returns through the same TC plumbing as your transfer. A standard caustic + acid + rinse cycle runs in 60–90 minutes without ever opening the vessel. You'd need to add a CIP pump and a spray-ball assembly — we sell both as accessories.
If your pump and controller use tri-clamp fittings or standard 1.5" TC adapters, yes. If your existing brewhouse runs on threaded NPT, you'll want a small kit of TC-to-NPT adapters — we can include them at checkout, or ship them on their own. Email us your gear list and we'll send back exactly what you need.
The 15G, 20G, 30G, and 50G Mash Tuns ship with a hinged grain access door welded into the side of the vessel. The 10G Mash Tun ships without a grain door — spent grain is removed via the false bottom at that scale.
2 years full warranty on the vessel, every weld, and every tri-clamp port. Lifetime parts support — gaskets, clamps, butterfly valves, sight glasses are all standard sanitary tri-clamp consumables. Serviced, not replaced.
No tilting. No pickup tube. No left-behind wort. The same welded drain pulls a clean transfer and a clean CIP rinse.
