SCALE BLOCK SINGLE APPLIANCE SCALE INHIBITOR

Point Of Use Limescale Protection

The Scale Block Single Appliance Scale Inhibitor is the perfect solution for preventing limescale at the point of use. Whether it’s an existing tap, shower, or water-using appliance, this compact system offers a powerful, salt-free alternative to conventional water softeners. Suitable for flow rates of up to 4 litres per minute, this low-maintenance, eco-friendly system offers true ‘fit-and-forget’ convenience, reducing existing limescale deposits over time and providing long-term protection for your plumbing and appliances.

How Does The Scale Block Work?
Utilising innovative Template Assisted Crystallisation (TAC) technology, the system converts limescale-forming minerals like calcium and magnesium into harmless micro-crystals. These crystals remain suspended in the water, preventing them from adhering to pipes, heating elements and surfaces, all while keeping your water’s natural mineral content intact.

How Long Does The Filter Cartridge Last?
With a lifespan of up to 1 year, replacing cartridges is quick and easy. Simply shut off the water supply to the system, open the housing using the spanner provided and replace the old cartridge with a new one.

Please note if new copper pipework is used on the feed then the system needs to be passivized for a minimum of 4 weeks before installation

 Trustindex verifies that the original source of the review is Google. First time using this company and product and i wasnt dissappointed. Communication was easy and quick resulted in an easy order and now having fitted the filter i can say its a great product easy to install and appears good quality apart from the four mild steel bracket screws stainless would have been better considering the environment these are fitted. All in all, very pleased and would highly recommend .

 Trustindex verifies that the original source of the review is Google. Excellent local company and genuinely lovely people to deal with. Really helpful and knowledgeable, with great advice about my water softener and the correct salt to use. They even gave me some resin cleaner at no charge, which was a very kind gesture. Fantastic friendly service and I’ll definitely be returning for my salt in future. Highly recommended.

 Trustindex verifies that the original source of the review is Google. Excellent service.  Product proved my softener was not working as it should.  I fully serviced it and cleaned with Resin Clean returned to service and it is now working as designed.  Very pleased.

 Trustindex verifies that the original source of the review is Google. If you're thinking about a water softener then i HIGHLY recommend Ultra Soft Water Softeners Ltd.

Great softeners and exceptional customer service. The water softener I bought needed some adjustments with the installation setup where I supported throughout. The customer service is honestly next level. I had countless calls with Becky Gillett, the Sales Manager, over a period of months to get to the bottom of it. She was incredibly patient with me, staying on the phone and doing video calls to walk me through the programming instructions step-by-step while I changed the settings and ensured all was installed correctly.

All the staff here have been great, but Becky really stuck with me from start to finish to make sure it was sorted and working well. It runs like a dream now.

HIGHLY recommend them!

 Trustindex verifies that the original source of the review is Google. Easy to order, quick delivery, good communication. Resclean worked a treat; one treatment cycle and soft water is back again from our 12 yr old softener!
