Water Treatment & Filtration in Daventry

Up on the Northamptonshire uplands, Daventry draws a hard supply — firmly hard-water country. If you live in Daventry, your water is hard. Very hard. Anglian Water's supply in this area regularly measures above 300mg/l calcium carbonate — that's well into the "very hard" category. You'll see it on your taps, in your kettle, around your shower head, and inside your boiler where it quietly shortens the life of every heating element and pipe it touches.

Fit a softener and the scale never reaches the rest of the system — in a Daventry home the boiler, cylinder and taps all last longer for it. A water softener stops limescale at the source. It treats your entire water supply before it reaches a single tap, so every fixture, appliance, and pipe in your home is protected. Your shower glass stays clear, your boiler lasts longer, you use less detergent, and your skin and hair feel noticeably different soon after fitting. It's one of those upgrades that pays for itself.

Softened water isn't to everyone's taste, so many Daventry kitchens keep the cold tap unsoftened with a filter for drinking and the kettle. For drinking water, reverse osmosis is the gold standard. An RO system fits under your kitchen sink and feeds a dedicated tap on the worktop. It strips out chlorine, fluoride, heavy metals, pesticides, and dissolved minerals that a standard filter can't touch. If you want the cleanest possible drinking water without buying bottles, this is how you get it. Carbon filters, sediment filters, and boiling/chilled water taps like Quooker and Grohe Red are all fitted by the plumber too.

Water Treatment Questions

Yes. Daventry sits in one of the hardest water areas in the UK. Anglian Water's supply in this area regularly measures above 300mg/l (very hard). That's why limescale builds up so fast on taps, shower heads, kettles, and inside your boiler and pipes. A water softener is the most effective long-term solution.
A water softener removes calcium and magnesium (the minerals that cause limescale) from your entire water supply using ion exchange. A water filter removes contaminants like chlorine, sediment, and heavy metals from your drinking water. They solve different problems. Many households in hard water areas benefit from both — a softener on the mains and a filter or RO system at the kitchen sink.
Reverse osmosis (RO) forces water through a very fine membrane that blocks contaminants, heavy metals, chlorine, fluoride, and dissolved minerals. The result is exceptionally clean drinking water. An RO system fits under your kitchen sink and typically feeds a dedicated tap on the worktop. Your plumber installs the unit, connects it to your cold supply, and fits the tap.
Water softeners are usually installed where the mains water enters your property — typically in the kitchen, utility room, airing cupboard, or garage. The unit needs a power socket, a drain connection for the regeneration waste water, and access to the incoming mains pipe. A verified local plumber surveys your property and finds the best location.
Softened water contains a small amount of sodium from the ion exchange process. Most people don't notice any taste difference. However, if you prefer unsoftened drinking water or have a low-sodium diet, a separate hard water drinking tap can be fitted at the kitchen sink that bypasses the softener, so you always have the option.
A typical household water softener uses one 25kg bag of salt every 4–8 weeks, depending on water usage and hardness level. Block salt or tablet salt is inexpensive per bag. It's the only ongoing cost — there are no filters to replace on a standard softener.
Yes. Boiling water taps like Quooker, Grohe Red, and InSinkErator use built-in filters that need periodic replacement. Your plumber installs the tap, connects the filter housing and hot water tank under the sink, and shows you how to change the filter when it's due. A separate carbon or RO filter can also be added if you want cleaner cold water too.
