Feed & Expansion Tank Services — Traditional Systems, Expert Care

While many homes have moved to pressurised systems, thousands still rely on traditional feed and expansion tanks to regulate water levels and pressure in heating and hot water systems. These loft-based setups may be old-school, but with expert maintenance, they deliver dependable performance for years.

At HotLeaks, we clean, inspect, replace, or upgrade these tanks to meet modern efficiency and safety standards. Whether your system needs ball valve replacements, tank lining, insulation, lid protection or full replacement — we’ll do it cleanly and compliantly. We also check for signs of stagnation, contamination, or pressure imbalance that can silently cause major issues.

If your heating setup uses an open vented system, we’ve got the know-how to keep it flowing smoothly.
