DIMM Black Friday: 10% off all products, only on the MarketPlace Pro

Here it is: from Thursday 26 November to Monday 30 November 2026 at 23:59, DIMM is running its Black Friday for water treatment professionals. For five days, get 10% off all products on orders from €250 excl. VAT, only on the DIMM MarketPlace Pro.

Installers, heating engineers, resellers, pool specialists, technical departments and industry, in Belgium and France: here is what we are offering for this special weekend, and how to make the most of it.

1. The Black Friday offer at a glance

It's simple: throughout the event, a 10% discount applies to the entire MarketPlace catalogue as soon as your order reaches €250 excl. VAT. Water softeners, reverse osmosis systems, UV sterilisers, filtration, resins and filter media, valves and spare parts, consumables: the whole catalogue is included, subject to the conditions shown on the MarketPlace.

The offer is available online only, on the DIMM MarketPlace Pro, and reserved for professionals with a customer account.

2. Why now is the right time

Late November is often the moment to review your stock before winter and prepare early-year projects. Black Friday is a good opportunity to:

• restock consumables: filter cartridges, reverse osmosis membranes, UV lamps, salt and maintenance products;
• get ahead on scheduled projects: water softeners, under-sink reverse osmosis systems and filtration systems to install in the coming weeks;
• equip your van and workshop with common spare parts (valves, seals, fittings, filter housings) for winter call-outs;
• group your purchases into a single order to reach the €250 threshold and keep logistics simple.
