However, the 555 is what is known as a Hi- Flo and is supplied with two 22mm hoses. The softeners are exactly the same except for the connection sizes. Why two sizes? If you have what is known as a ‘Unvented Hot Water System’ where the domestic hot water cylinder is under mains pressure you must install the WS555 with the 22mm hoses provided. If however you have a vented hot water system (cold tank in the loft) with a copper cylinder for hot water; OR a Combi Boiler, the WS355 is the correct one using 15mm hoses. **Q: What are the annual running costs? Do you just have to buy salt blocks, anything else? Thanks, I am considering buying my 1st water softener.** A: Hi, Thank you for your question about the WS555 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 WS555 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. 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 **Q: can this be fitted if we have a hot water tap** A: Hi, thank you for your question. If the hot water tap is for drinking, then it is not ideal to supply it with softened water. If you have any more questions regarding, please feel free to ask. Kind regards, BWT Marketing Team **Q: Is the water safe to drink or tastes of salt?** A: Whilst small quantities of salt softened water are probably ok to drink, this is NOT recommended, so you would need to separate soft (e.g. shower, bath, loos) water pipes from hard (e.g. drinking taps and water for kettle) - I haven’t noticed if our softened water tastes of salt in the shower etc so any taste would be subtle, but I don’t recommend that you try! Hope that helps. More detail on the BWT website. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Working superbly so far *by on Reviewed in the United Kingdom 8 October 2025* Yey!!! It’s in and working beautifully may it continue..We are absolutely thrilled,we badly missed our old ancient softner and the one we ordered to replace it was faulty.. this time we chose one with 5 star customer service rating and that alone and have peace of mind..The pipes included were too hard to install but we were able to use ones from our previous one..I cannot as yet comment further as it’s only day one but beautiful silky water and no scum on our tea and stained cups, shiny sinks again.. doing its job ### ⭐⭐⭐⭐⭐ Needs separate access to waste pipe *by on Reviewed in the United Kingdom 25 December 2020* My plumber installed this water softener and said that it is a good machine and easy to install and set up.After about a week, we could really notice the effectiveness of the WS555. Our shower is clean, the top shower spray is clean and the water comes out in straight lines!The dish washer is cleaner. Washing hair is easy and doesn't require after shampoo. we are going to save a lot of money on cleaning products that we now do not need. Every home should have a BWT water softener. Ir's a necessity. ### ⭐⭐⭐⭐ 4 Stars *by on Reviewed in the United Kingdom 3 July 2024* Summary: Very good item when working but with design flaws that if improved would be a 5 star product. great customer service from BWT and faultless delivery.Delivery was faultless, very clear on when it was going to be delivered and arrived on time and undamaged.The softener comes with almost everything you need including valves and flexi-hoses with the exception of a Pressure Reducing Valve (not necessarily required) and overflow pipework (except two elbow joints - one on the unit and one spare).The item itself is very good overall but with some big areas for improvement. Being a bulky item, it was not particularly easy to remove from the packaging or move around in general. Subtle indents on the unit could be useful to ease movement if required. Added to that, is the poor lid design that falls apart at the slightest touch into two pieces. The two pieces could do with either being permanently attached together or at the very least clipped together and to the unit. The very top piece with the display screen is attached to the unit by delicate cables which is a recipe for disaster given how easy it is to dislodge. This leads on to my next issue...Error message 'Err 1' - this frustrated me for a whole Sunday when trying to set up the softener going through litres and litres of water. I had all the correct plumbing connections but could not figure out why I was getting the error message.I phoned BWT customer service on the Monday as I could not find any guidance online or in the installation manual except to ring BWT. The customer service was brilliant, by far the best customer experience I have received in a very long time. They arranged for an engineer to visit the next working day (Tuesday) as it couldn't be sorted over the phone.Upon hanging up, I rechecked what I was told on the phone and noticed that two prongs on the grey cable had been dislodged from their connections on the motherboard next to where the power supply is plugged in to the unit. (this appears to be a common problem) I plugged them back in; retried the installation and it worked perfectly within minutes. I can only assume these cables became dislodged when accidentally knocking the unsecure lid off (my fault I suppose - but poor design).I phoned to cancel the engineer appointment but BWT explained they carry out a Free of Charge Commissioning Service to ensure correct installation so they proceeded with the call out - Again, great customer service! The engineer was not surprised when I explained the error message issue. He checked the set up, water pressure, water hardness (as he was surprised I had set it so high), and the unit itself.Now installed correctly the unit works perfectly and produces perfectly soft water. A testing kit is included with simple instructions of how to test for water hardness and how it corresponds to configuring the water softener. Living in Oxfordshire we have extremely hard water (400ppm - tested by me using the kit provided, and by the engineer). The water softener is easily adjustable to suit this. ## Frequently Bought Together - BWT WS555 Hi Flow Luxury Water Softener (compatible with salt or tablet) 14 Litres - BWT Water Softener Block Salt SALTBLO 8 kg (Set of 2 Pieces) - pack of 3 Water Softener Salt Blocks 100% Genuine Food Grade water softener salt block Compatible to All Water Softener Machine, Best For Laundry Kitchen Dishwasher Industrial use Salt Block 3 pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/65944799-bwt-ws555-hi-flow-luxury-water-softener-takes-block-tablet](https://www.desertcart.jp/products/65944799-bwt-ws555-hi-flow-luxury-water-softener-takes-block-tablet) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-09*
