FAQs
What is a dual-flush cistern and how does it save water?
A dual-flush cistern is a toilet mechanism that offers two flush options: a reduced flush (usually 3 litres) for liquid waste and a full flush (around 6 litres) for solid waste. By allowing users to choose the smaller flush when appropriate, households in Lancing can cut toilet water use by up to 50 %, saving both water and money on metered bills.
Can my existing toilet in Lancing be retrofitted with a dual-flush cistern, or do I need a complete replacement?
In many cases we can retrofit a dual-flush drop-in valve or replace the entire cistern lid and mechanism without disturbing the pan. However, if your pan is very old, cracked, or uses an uncommon coupling size, a full close-coupled or back-to-wall toilet replacement may be more cost-effective. We carry out a free on-site survey in Lancing to confirm the best option before work begins.
How long does a typical dual-flush cistern installation take?
A straightforward retrofit or like-for-like cistern swap normally takes 1–2 hours, including testing and tidy-up. Full toilet replacements that require new fixings, waste pipe adjustments, or floor resealing can take 3–4 hours. We always schedule appointments so you are never left without a working toilet overnight.
Are there any local water regulations or incentives for installing water-efficient toilets in West Sussex?
Building Regulations Part G specifies maximum flush volumes of 6/4 litres for new toilets across England, and dual-flush cisterns comply fully. Southern Water, the local supplier for Lancing, periodically runs Water Efficiency voucher schemes that may cover part of the upgrade cost; we can advise you of the current offers and prepare the paperwork if needed.
What warranty and after-care do you provide on dual-flush cistern upgrades?
We supply WRAS-approved flushing valves and cistern parts that come with a 5-year manufacturer warranty. Our labour is guaranteed for 12 months, during which we will return free of charge to resolve any leaks, flushing issues, or adjustment needs. We also keep common service parts in stock for rapid call-outs after the guarantee period.
How much does it cost to upgrade or replace a toilet with a dual-flush system in Lancing, and what affects the price?
A basic retrofit or cistern-only replacement starts from £120 including parts, labour, and VAT. A full toilet suite replacement (pan, cistern, seat, and sealant) typically ranges from £250–£450, depending on the style (close-coupled, back-to-wall, or wall-hung), accessibility to pipework, and any flooring repairs required. We provide fixed quotations after a free survey so you know the exact price before we begin.
