Comes with two 22mm flexible hoses but prefer copper. This unit has run without any issues for 7 years. Just booked a service as one of the seals has failed, should be serviced every 2 years, model still made and all parts are available. Would purchased again if needed. Review: Great piece of kit - Bought the WS 455 as a replacement for a well used old model located under my sink (a very tight fit). Following discussions with the BWT customer service team mainly around measurements and capacity, I decided on the 455 rather than one of the larger capacity models. Self installed, the 22mm installation kit was difficult to work into the available space, but got there in the end. We live in a very hard water area which tested at 390ppm, four bedroom house, average water consumption. 24 hours after commissioning water tested at 30ppm. This unit works well easily supplies our combination boiler, would recommend it. ## Features - Fits Most Kitchen Cupboards – Compact design for easy installation in tight spaces. - High Flow Performance – Ideal for power showers and modern plumbing systems. - Flexible Salt Options – Works with both block and tablet salt for convenience. - 22mm Hoses & Valves – Ensures maximum water flow without restriction. - Fully Automatic Operation – Just top up with salt, no manual intervention needed. - Smart Water Monitoring – Reduces water and salt usage for cost efficiency. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B077ZKKC2R | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 246,320 in DIY & Tools ( See Top 100 in DIY & Tools ) 153 in Under-Sink Filters | | Colour | Blue | | Customer Reviews | 4.4 4.4 out of 5 stars (63) | | Date First Available | 9 Dec. 2017 | | Included Components | Hi Flow Electronic Demand Block/Tablet Water Softener | | Installation method | Under Sink | | Item Package Quantity | 1 | | Item Weight | 22.5 kg | | Item model number | WS455 | | Manufacturer | BWT | | Material | Plastic, Stainless Steel | | Maximum Pressure | 5 Bars | | Measurement System | Metric | | Number of Pieces | 1 | | Part Number | WS455 | | Power Source | AC/DC | | Product Dimensions | 48 x 27 x 53.2 cm; 22.54 kg | | Size | 10 Litre | | Special Features | Scale and Scum Reduction | | Style | Softener | ## Product Details - **Brand:** BWT - **Special feature:** Scale and Scum Reduction - **Product dimensions:** 18.9L x 10.6W x 20.9H centimetres - **Package information:** Kettle - **Installation type:** Under Sink - **Power source:** AC/DC - **Item weight:** 22.54 Kilograms - **Model name:** WS455 - **Global Trade Identification Number:** 05060011262168 - **Manufacturer:** BWT ## Images ![BWT WS455 Hi Flow Electronic Demand Block/Tablet Water Softener, Blue, 10 Litre - Image 1](https://m.media-amazon.com/images/I/51zif3ARi7L.jpg) ![BWT WS455 Hi Flow Electronic Demand Block/Tablet Water Softener, Blue, 10 Litre - Image 2](https://m.media-amazon.com/images/I/614oQTqqr5L.jpg) ![BWT WS455 Hi Flow Electronic Demand Block/Tablet Water Softener, Blue, 10 Litre - Image 3](https://m.media-amazon.com/images/I/81OzanbjbKL.jpg) ![BWT WS455 Hi Flow Electronic Demand Block/Tablet Water Softener, Blue, 10 Litre - Image 4](https://m.media-amazon.com/images/I/8165I0OqtlL.jpg) ![BWT WS455 Hi Flow Electronic Demand Block/Tablet Water Softener, Blue, 10 Litre - Image 5](https://m.media-amazon.com/images/I/71rKRgHsafL.jpg) ## Questions & Answers **Q: How long does regeneration process take?** A: Hi, thank you for your question about the WS455 Water softeners only require periodically topping up of salt, water for the regeneration process and a minimal amount of electricity. The exact amount will vary depending on the size of the household and the local water hardness. Around 75 Lts of water and 1.2 Kgs salt produces 1600 Lts of softened water at 300 ppm hardness. The WS455 water softener is controlled by a microprocessor which constantly monitors water usage. The system will build up a history of your water requirements and calculate the most economical regeneration pattern, it would be around 1.5h using tablet salt. This will ensure a constant supply of softened water whilst maintaining high levels of water and salt efficiency. As this water softener uses a proportional brining system, more frequent regenerations do not necessarily mean higher water / salt usage. The saving on toiletries, household cleaning and laundry products can also offset any running costs reducing the impact on the family budget to a minimum. If you have more questions, please call us on 01494 8381 00 during normal office hours. Thank you! Kind Regards **Q: Does this get plumbed in to the water feeding the central heating? Thanks** A: It’s not a good idea to have your central heating filled with softened water unless it’s designed to do so. The softened water will create an environment that will corrode the aluminium used in the boiler components etc. Always use water straight from the mains supply. Also, don’t forget that you must also provide a separate unsoftened mains water supply for drinking water and cooking etc. A ‘Triflow’ type tap can be a good idea at the kitchen sink. **Q: Can the ws455 & ws555 be used with a direct system i.e. no header tank? thanks.** A: I fitted my ws555 direct to the water main coming into the house... there are no header tanks in my property... I followed BTW advice & installed it with the 22mm(?) fittings supplied & converted the immediate pipe work to suit... I have to say I’m more than happy with it... the water changed instantly... we use a lot but we’ve never had a problem with supply... great bit of kit at reasonable money! **Q: can I install it directly on the combi boiler ?** A: Dear customer, Thank you for your query. We would normally recommend that the WS455 is installed on the incoming mains water supply to ensure the whole house can benefit from BWT Luxury Water. There is no issue in using the softener to protect a single item and most Combi Boilers will benefit from being fed with softened water. However, you should always check with the boiler manufacturer and follow their advice before commencing work. If you have any further questions, please contact our customer service team on 01494 838 100 during normal office hours. Kind Regards BWT Marketing Team. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Awesome bit of kit! *by D***M on 22 August 2025* Awesome bit of kit, installed myself as simple to connect two 22mm copper pipes.
