John Murphy and Company have over 25 years in managing plumbing and heating projects in commercial and educational facilities, from the simplest of repairs to complete strip out and refurbishments of bathrooms, boilers, and extensive system overhauls. We manage single properties for home owners and private landlords and work with managing agents and property maintenance companies to carry out full plumbing and gas central heating maintenance for larger portfolios.

We currently carry out many servicing contracts in the surrounding area, providing detailed condition and defect reports along with certification to help identify any future problems, along with an onsite plant room file containing all relevant manufacturer’s instructions and service reports to assist our engineers and site staff. We also send out service reminders to ensure that clients are always up to date.

WINDSOR LEISURE CENTRE – MAIN GAS PIPE

As part of our large portfolio of commercial clients, we are often called upon for urgent leisure centre repairs. A recent example is a call out to a strong smell of gas. We were on-site within 30 mins, safely isolated the gas supply and identified a failed 6-inch iron gas main below the car park. We had to think fast to find a temporary solution to avoid impact on services such as no heating or hot water. We immediately ran a temporary MDPE gas main, materials were procured and RAMS issued the same afternoon. Within 24hrs the new temporary pipework was installed, all appliances were re-commissioned and the centre was back fully operational.

A permanent solution was then specified. After carrying out a detailed Topographical and Underground Utility Survey, during excavation we discovered that the failed iron pipe had been teed into with a new MDPE pipe serving one of the areas, we strength and tightness tested this pipework and it was re-used. This saved the client in excess of £4k from our original quotation. The MDPE pipework was strength tested whilst all-steel pipework was fabricated on site. We also ran 2x individual supplies to points of use, including individual isolation valves, meaning should a problem ever occur in the future each leg could be individually isolated to avoid major disruption to the centre. The project ran smoothly and was completed within 3 1/2 weeks; our original program indicated 4.
