How to Prevent Pipes from Freezing This Winter

Comments Off on How to Prevent Pipes from Freezing This Winter

It’s time to dig out the de-icer and woolly hats. Winter is well and truly here now. That means you’ll be cracking on the central heating. But what if there’s a problem with your pipes?

Frozen pipes are bad news for your plumbing. While frozen pipes are less likely to be an issue nowadays, they can still happen, especially with minimal insulation.

Why frozen pipes are such a big problem

Water expands when it freezes which can put a lot of pressure on the pipes containing it. This can cause pipes to break which eventually causes leaks when they thaw. This can then lead to water damage and disruption.

You’re more likely to find this problem in pipes that are exposed to severe cold outside or water supply lines in unheated areas of a building like basements and attics. Pipes that run against exterior walls that have little or no insulation are also at risk.

Inspect all pipes leading into home

Take a look at all pipes leading into the home as these are the ones more likely to freeze as they’re more exposed to the elements. These are the ones you’ll have to target and insulate.

Pipe lagging

This is a relatively cheap solution and is available from plumbers and DIY stores. It involves using a tube of polystyrene material to insulate pipes going into the building.

Fill gaps around pipes

Besides lagging pipes, you should also try insulating the gaps around pipes as they enter the property. You can do this by using a good quality expanding foam product that will seal the hole completely. This ensures that your pipes are insulated and that any cold air is kept out of your home.

Keep your home heated

It probably goes without saying but the warmer your home is the less likely pipes are to freeze. If you know you’re going to be away during the winter months you might want to leave your heating on a timer so the temperature doesn’t drop too much.

Insulate your home

If you still have a water tank in the loft, this probably needs to be lagged and the loft needs to be well insulated too to prevent water damage.

Well insulated homes are less likely to have issues with frozen and burst pipes. So if your house isn’t keeping heat in, you might need to invest in better insulation.
