Hard water in Hertford

Affinity Water's 2025 report for the Hertford supply zone measured an average total hardness of 318 mg/l (as calcium carbonate) — “very hard” on the Drinking Water Inspectorate's scale. See every town’s figure.

Hertford's centre has plenty of older property where the rivers meet, with post-war homes at Sele Farm and family houses out in Bengeo and Foxholes. In family homes the softener usually fits neatly under the kitchen sink, in a utility room or in the garage.

Older Hertford homes often have cylinders and immersion heaters that have scaled up over the years. If you're replacing a cylinder, fitting a softener at the same time helps the new one stay efficient.

What fitting a softener involves

We find the best place on your incoming main — usually under the kitchen sink, in a utility room or in a garage. The softener goes in with a bypass so it can be isolated for servicing, and a non-return valve on the supply.

We usually fit a separate unsoftened drinking-water tap at the kitchen sink, run the drain and overflow properly, then set the softener up and show you how it works.

Supplied by us or by you — either way, you get a fixed quote before any work starts.
