Pipework Protection

Pipework and its various fixtures and fittings that live in areas that are susceptible to very cold weather really need to have some kind of protection so that they will not freeze and cause major problems for the homeowner. If you are confused or need help, then, you can call a professional plumbing service like Hammersmith Plumbers. Cisterns and Loft Tanks:The appliances that are fitted in lofts must be totally insulated. The bottom of the cistern is left un-insulated and there is no lagging material immediately underneath so heat that rises up from the rooms below can help reduce the risk of freezing. Insulating water storage cisterns has an additional purpose, because the regulations state that water in a storage cistern must not be allowed to exceed 25 degrees C, so the insulating material has a double benefit by preventing absorption of heat. Always make sure to insulate overflow pipes from water storage cisterns.Pipework:Supply pipework that rises through a solid floor usually only requires insulation if they are close to an outside wall. Overflow pipes that are exposed and drip water can also be a freezing risk, because water freezes and turns to ice and expands in size by around 10%. So if this takes place inside a pipe it will expand and split. While it stays frozen, obviously the water cant escape. When it melts, however, the split in the pipe, or the fitting will start leaking and the damage can be massive. Example:It might be a good idea to drain down a section of pipework as recommended by a Hammersmith Plumber. Lets take a pipe that runs outside to supply a garden tap at the rear of the house. If the tap is only used in the summer months, isolate the supply and drain any excess water before the winter. Insulating Material:Insulating material can be cut to length. For elbows and T pieces the insulation might need cutting to suit. At sweeping bends the insulation will normally flex enough. For At fittings like stop-valves, make sure the whole body is insulated , but leave the head free to be used.
