Commercial Water
Tank Repairs

Fast, compliant repairs for commercial cold water storage tanks, from leaking joints and failed valves to damaged lids, screens and insulation, with 24/7 emergency cover.

A small fault in a cold water storage tank rarely stays small. A weeping joint becomes a leak, a stuck float valve floods a plant room, and a cracked lid lets in the debris and insects that lead to contamination and Legionella risk. Express Water Tanks repairs steel and GRP cold water tanks for hotels, office blocks, apartment buildings, property managers, public sector buildings and development projects, and our engineers are available 24 hours a day, 365 days a year.

Common Water Tank Repairs

• Leaking joints and panels – resealing and repairing weeping joints, damaged panels and failed seals on sectional tanks
• Float and ball valves – replacing faulty valves that cause overflowing, low levels or poor turnover
• Valves and pipework – replacing corroded or failed isolation valves, inlet and outlet pipework and connections
• Lids and covers – replacing missing, cracked or poorly fitting lids so the tank is sealed against light, insects and debris
• Vents, overflows and warning pipes – fitting insect screens and correcting overflow arrangements
• Insulation – repairing or replacing insulation to keep stored water cool and protect against frost
• Access and safety – stainless steel and GRP ladders, handrails and roof edge protection
• Byelaw and L8 upgrades – bringing older installations up to current water regulations, including cross flow arrangements to improve turnover

Emergency Water Tank Repairs

If your tank is leaking, overflowing or the building has lost its water supply, call us on 01206 239804. Our engineers are available around the clock for emergency call-outs, and where a tank needs to come out of service we can set up a mains bypass or temporary tank to keep the building supplied while the repair is carried out.

How We Handle Planned Repairs

1. Survey – an experienced, certified engineer inspects the tank, access and pipework and identifies the cause of the problem.
2. Quotation and RAMS – you receive a detailed quotation with a risk assessment, method statement and estimated timescale of works.
3. Repairs – our own in-house engineers carry out the work, with no sub-contractors, and a temporary supply where needed.
4. Chlorination and handover – where the work has affected the stored water, the tank and pipework are chlorinated before the system goes back into service.

Repair, Refurbish or Replace?

Repairs are the quickest and most cost-effective fix when the tank itself is sound. Where corrosion or leaks are widespread, refurbishment and relining may give the tank a new lease of life, and where a tank is beyond economic repair we can quote for cold water storage tank replacement or a new GRP sectional tank. If the tank simply needs cleaning, see our water tank cleaning and servicing. For the rules your tank needs to meet, read our guide to cold water storage tank regulations.
