Connector for attaching the 8 mm feeding tube to a water tank, barrel or reservoir.
Drill the correct opening in the reservoir, install the tank connector, attach the 8 mm feeding tube, and place the tank above the plants for gravity-fed watering.
One 8 mm tank connector.
Required for any Blumat Drip system fed from a tank, rain barrel, or other gravity reservoir. Not needed if you're feeding your system from a tap, hose, or pressurized line. Those need a pressure reducer instead.

Installation Guide
How to Set Up Your System
Takes just a few minutes. Once set up, your plants water themselves.
Step 1
Pick the Spot
Mark a spot 2 to 4 inches up from the bottom of your reservoir, on the sidewall. Leaving room at the bottom lets sediment settle below the connector instead of getting pulled into your tubing and sensors.
Step 2
Drill a 1/2" Hole
Drill a 1/2" hole at your marked spot. A step bit is the cleanest tool for the job — it cuts thin plastic without cracking or chipping the wall — but a standard 1/2" twist bit works fine on most plastic reservoirs if you go slow and steady.
Step 3
Install the Connector
Push the threaded nipple through the hole from the inside of the tank, with the rubber gasket sealing against the inner wall. Thread the locknut on from the outside and tighten by hand until the gasket is fully compressed against the wall.
Step 4
Connect the Tubing
Push 8 mm feeding tube fully onto the outlet barb. Position your reservoir at least 24-36 inches above your plants for steady gravity flow, then fill and check every connection for leaks before walking away.
Keep the tank above 1/4 full
The weight of the water above the connector is what pressurizes the system. Once it drops below about a quarter of the reservoir's capacity, flow gets unreliable and if the tank runs fully dry, sensors can lose their water seal and cause flooding.
Check the reservoir height
Gravity-fed systems need the water reservoir to sit higher than your plants — ideally at least 36 inches above the soil to build the 5-10 PSI pressure needed for steady flow.
PLANT DRIVEN WATERING
Never Water Your Plants Again
Most watering systems run on a timer. Ours runs on a plant. No timers, electricity, or apps needed. Set it up in 30 minutes with only a pair of scissors. Powering greenhouses and home gardens across Europe since 1965 and now available in the USA.
A Closed System You Control
A reservoir gives you something a tap never can: a fixed amount of water that you chose. No hose running 24/7 if something goes wrong.
Any Tank, Any Reservoir
Rain barrels, 5-gallon buckets, indoor tanks, raised water containers. If it holds water and you can drill a hole, you can feed a Blumat system from it.
Install in About Five Minutes
Drill a hole, push the connector through, tighten the locknut, push on your tubing. The whole install takes about as long as making coffee.
For the Next Plant
It's nice to have extra fittings on hand for those times new plants just show up at your house
The Fun Part
Building a Blumat system is honestly satisfying. Every part slides together cleanly, and you can rearrange the whole layout in an afternoon if you want.
Austrian Engineering
The same precision that makes Blumat sensors work for 60+ years lives in every connector, valve, and tube in the catalog.

How Blumat Fittings Work
Confirm the Size
8 mm fittings only work with 8 mm supply tubing. 3mm fittings work with 3mm drip tubing
Cut Tube
Use sharp scissors or a tube cutter for a square cut. Crushed or angled cuts leak.
Push It On
Seat the tubing fully onto each barb of the fitting. A snug fit holds without clamps or glue.
Test the Flow
Run water through the system and check for leaks before walking away.
Walk Away
Once it's installed and tested, you're good to go.

You Want Peace of Mind
No hose left running, no spigot to worry about while you're away. If something malfunctions, you will only drain the reservoir.
You're Catching Rainwater
Rain barrels are an ideal Blumat water source. Natural, low-pressure, and free. The tank connector gets it from the barrel to your sensors.
You Mix Nutrients Into Your Water
You can add nutrients to reservoir systems and fertilize dozens of plants from one tank.
You Want to Conserve Water
Reservoir-fed systems use exactly what you put in. Combined with Blumat's demand-based sensors, every drop ends up at a root.
