Geberit (Germany)
Premium Quality, Industry Leader
Strengths
Exceptional Build Quality
German engineering precision, premium materials, longest lifespan (8-12 years)
Hard Water Resistant
Best performance in Hampshire/Wiltshire hard water, limescale-resistant coatings
Comprehensive Range
Type 290, 380, Sigma series - options for every cistern type and budget
Industry Standard
Specified by architects/developers, used in commercial projects, excellent spares availability
Weaknesses
Premium Pricing
2-3x cost of budget brands, may be overkill for rental properties
Complex Installation
Some models require more expertise than budget alternatives
Popular Models:
- • Type 290: Standard dual flush (£35-45)
- • Type 380: Premium dual flush (£45-55)
- • Sigma series: Concealed cisterns (£50-60)
Professional Recommendation:
BEST CHOICE for: Long-term family homes in hard water areas (Hampshire/Wiltshire), premium properties, commercial installations. The higher upfront cost is justified by exceptional longevity and minimal service issues. In my 15+ years, Geberit valves have the lowest callback rate.
Thomas Dudley (UK)
Reliable British Manufacturing
Best Features
- • UK-made reliability
- • Excellent value for money
- • Wide product range
- • Good hard water performance
Considerations
- • Shorter warranty than Geberit
- • Medium lifespan (5-8 years)
- • Some budget models less durable
Top Models
- • Turbo 88 (£18-25)
- • Vantage (£25-35)
- • Hydroflo (£22-30)
Professional Recommendation: Excellent mid-range choice for homeowners wanting British quality without Geberit premium pricing. Turbo 88 is workhorse valve I install most frequently in standard domestic properties.
Fluidmaster (USA)
American Innovation, Global Availability
Strengths
- • Excellent 5-year warranty
- • Very hard water resistant (PRO line)
- • Universal compatibility
- • Available everywhere
Weaknesses
- • American design (some UK fitting challenges)
- • Budget models less robust
- • Less premium than Geberit
Best Models
- • PRO750UK (£28-40) - Best
- • PRO55B (£20-30) - Good
- • Universal valve (£18-25) - Budget
Professional Recommendation: PRO750UK specifically designed for hard water is excellent Hampshire choice. 5-year warranty outstanding. Slightly less refined than Geberit but excellent value.
Macdee (UK) - Heritage Brand
£15-30 | Good quality, competitive pricing
Best for: Budget-conscious homeowners, rental properties, straightforward replacements
Top models: Metro (£15-22), Kayla Dual (£22-30)
Pro note: Reliable budget option but shorter 3-5 year lifespan in hard water. Fine for rental/budget situations but I recommend Dudley/Geberit for owner-occupied homes.
Wirquin (France) - Budget-Friendly
£15-28 | Economical option, adequate performance
Best for: Very tight budgets, temporary fixes, landlord quick replacements
Top models: Jollyfill (£15-22), Sirocco (£18-28)
Pro caution: Acceptable for emergency/budget situations but I see more callbacks with Wirquin in hard water areas. Recommend upgrading to Dudley/Fluidmaster within 2-3 years.
