Hampshire Hard Water Note
These costs assume Hampshire's hard water (300mg/L+) which reduces filter life by 30-50%. In soft water areas, annual filter costs would be lower. Consider adding an Aquabion water conditioner to extend filter life and reduce ongoing costs.
DIY Installation: What You Need
Tools Required
Total Tool Investment
If you don't own these tools: £70-125 one-time cost. If you already have basic tools: £0-30. Compare this to professional installation cost of £125+ to decide if DIY makes sense.
Common DIY Mistakes
Not Turning Off Water
Always isolate the supply before cutting pipes. Know where your stopcock is!
Wrong Size Connections
UK pipes are typically 15mm. Check before buying. US filters often use 3/8" fittings.
Forgetting to Flush
New filters contain carbon dust. Always flush 5-10 litres before drinking.
Over-Tightening
Plastic fittings crack easily. Hand-tight plus quarter turn is usually enough.
Recommendations by Household Type
Not sure where to start? Here are our recommendations based on household type and needs.
Single Person / Renter
Portable, no landlord permission needed, low commitment
Couple / Small Flat
Good capacity for 2, convenient, reasonable cost
Small Family (2-3 kids)
Higher capacity, better filtration for cooking/drinking
Large Family (4+ kids)
All taps protected, handles high usage, protects appliances
Health-Conscious
Maximum contaminant removal, purest water
Eco-Conscious
Reduces plastic waste, sustainable filters available
Hampshire Hard Water: Budget Impact
Living in Andover (SP10/SP11), Marlborough (SN8), or Hungerford (RG17)? Our extremely hard water (300mg/L+) significantly affects your filter budget.
Cheap Filters Fail Faster
A £25 jug filter rated for 150L might only last 100L in Hampshire. That's 33% more filter costs than the manufacturer claims.
Pre-Filters Save Money
Adding a £20/year sediment pre-filter can extend your main filter life by 30-50%. Net saving: £20-50/year on premium filters.
Consider Aquabion
An Aquabion water conditioner (£350 installed, lasts 5+ years) reduces sediment reaching your filters. Combined with filtration, it's often the most economical long-term solution.
Budget Reality Check
Cheapest isn't always best value. In Hampshire's hard water, a £100 quality filter lasting 4 months is often better value than a £50 filter lasting 2 months. Do the maths for your situation.
