How much water is wasted when the toilet "runs"?

A typical leaking flush valve wastes 300–800 L a day. Over a month — 9–24 cubic meters. At 2026 Israeli tariffs that is ILS 70–180 a month = ILS 1,000–2,000 a year. The repair pays for itself in 2–3 months.

How fast can the mechanism be replaced?

For an experienced plumber — 30–45 minutes, of which 15 are draining the tank and dry-fitting. If the tank is wall-hung (via the service hatch) — 60–90 minutes due to awkward access. In rare cases (old tanks with non-standard systems) — up to 2 hours.

Can the mechanism be replaced without removing the tank?

Yes, it's the standard procedure. The tank stays on the toilet, all work is done through the top opening. Removing the tank is only needed if it has cracked or if the tank-to-bowl gasket needs replacing.

Is it worth upgrading to an expensive mechanism if the budget one works?

Budget Siamp or Fluidmaster (ILS 150–200) — works great, lasts 5–8 years. Premium Geberit (ILS 400–600) — 10–15 years, quieter. For standard residential use the difference is not critical. For a wall-hung Geberit frame — fit a Geberit mechanism (compatibility and longevity).
