Common questions about product categories
How do I know if this product is compatible with my system?

It depends on the type of connector/coupler, thread sizes, tube diameter, and use (beer/gas). If you send us your setup or a photo, we’ll confirm it for you.
What information should I check before buying?

Keg/connector type, threads, inner/outer tube diameter, fitting type, and working pressure/temperature.
Is it suitable for both craft and industrial beer?

Yes. The key is to correctly adjust pressure/temperature and maintain proper cleaning.
Can I use it for drinks other than beer?

In many cases yes (wine, vermouth, and others), but it’s best to confirm materials and pressure/cleaning requirements depending on the beverage.
Is it easy to install or do I need tools?

Many components are easy to install, but for professional setups we recommend a clean cut on the tubing, proper tightening, and leak testing.
What should I do if there are gas or beer leaks after installing it?

It’s usually caused by incorrect measurements, a worn gasket, or insufficient sealing. We’ll help you detect it and choose the right gasket/fitting.
Why am I getting too much foam?

Usually due to high temperature, incorrect pressure settings, an unbalanced line, air entering the system, or insufficient cleaning.
What pressure should I use to serve properly?

It varies depending on style, temperature, and line length/diameter. We’ll guide you to balance your system and achieve a stable pour.
How often should I clean the lines?

It depends on consumption, but regular cleaning prevents off-flavors/odors, foam issues, and breakdowns, and reduces waste.
Do you offer technical support as well as selling equipment?

Yes. We’ll advise you to ensure compatibility, correct installation, and proper pressure/temperature settings. We also have a technical service for diagnostics, maintenance, and system optimization.
How long does shipping take and how is the cost calculated?

The timeframe depends on the destination and order size. The cost is calculated automatically at checkout based on weight/dimensions and address. If you need urgent delivery or a bulky order, we’ll help you choose the best option.
Can I return a product if it’s not the right one or I don’t need it?

Yes. We accept returns within the specified period, as long as the product is unused, in perfect condition, and in its original packaging. To request a return, contact us with your order number and the reason.
What should I do if the product arrives damaged or something is missing from my order?

Write to us as soon as possible with photos of the packaging and the item. We’ll review the case and arrange a replacement, reshipment, or the most suitable solution.
Can I buy just one unit or is there a minimum order?

Yes, you can buy single units for most products. If any item requires a pack or has a minimum quantity, it will be clearly indicated on the product page.
Do you ship internationally outside Spain?

Yes. We ship throughout Europe and also to North, Central, and South America. Shipping cost and delivery time are calculated by destination at checkout; if you need an urgent option or a bulky shipment, get in touch and we’ll advise you.
