Product Description
This pressurized diaphragm tank is designed to stabilize water pressure for coffee equipment, particularly in locations where the incoming water supply is weak or inconsistent. Inside, a flexible diaphragm separates compressed air from water, allowing the tank to store pressurized water and release it when the machine demands flow.
Perfect for:
Espresso machines needing steady brew and boiler refill pressure
Sparkling water systems with carbonation units
Environments with unreliable municipal or well water supply
The tank stores water under pressure and delivers it instantly when the espresso machine or tap opens, preventing pressure drops that can damage equipment or affect performance.

Excellent experience with Genius. They diagnosed the problem and repaired my DeLonghi PrimaDonna machine. They did exactly what they said they were going to do, did it on the timeline they predicted and for what they quoted. Communication was clear and the staff were friendly and helpful. They shipped it back to me for a reasonable price. Happy to have the machine back. Highly recommend this company.

Clear, open, and friendly(!) communication throughout. I was given an estimate with an in-depth explanation of the anticipated repair and associated costs. The work was completed ahead of schedule and to the highest standard. When I say the machine is now better than new, I mean it: shots of espresso taste the same, but the coffee has gone from “fine” to *incredibly good.* Genius Coffee N’ Espresso stand by their repairs with a 3 month warranty on the work.

Fantastic group of people that truly know their craft. I have an older machine that unfortunately doesn't have parts available anymore. Despite this, the team at Genius Coffee spent time with me and helped me diagnose the issues. They spent lots of time explaining the way the machine works, communicating technical details and inspected the machine. In the end, I just needed to replace a broken o-ring. The part was a couple of bucks. They invested lots of time in helping me, so while they didn't make money on this transaction, they've won a customer for life!!! I couldn't recommend this place more. Team of truly helpful and knowledgeable people. Excellent communication and customer service.

I ordered a hard to find part (Breville BES870 Pressure Gauge) at a great price with reasonable shipping cost. Easy ordering and tracking. It arrived (to US address) quickly, well packaged (by Irma) and as advertised

Helpful, responsive, pleasant service. Machine repair queue is long but that’s not a fault of Genius; it’s long at every place I called. Strongly recommend
