Bathrooms are often notoriously tight spaces. Plumbing the smallest room in the house certainly means any flexibility is welcome. When it comes to plumbing a flexible soil pipe can offer many advantages over its traditional, rigid counterpart and can be used in spaces a rigid soil pipe wouldn’t be suitable.

The Need for Flexible Pipes

As bathroom suites are reconfigured and washbasins, toilets and baths are moved to accommodate the space and size of the fixtures, it isn’t uncommon for the plumbing to align imperfectly with the back of the toilet. This means a traditional, rigid, pan connector would be difficult to use.

To accommodate this common problem, a large range of flexible pipes are now on the market.

Types of Flexibility

Making sure a leak doesn’t occur is very important when plumbing a toilet so a quality flexible soil pipe which can do the job in the tightest of spaces is welcome.

There are two types of flexibility available:

  • Extendable – pipes are available in different lengths, and can be extended or retracted to cover the distance between the back of the toilet pan and the waste pipe. The maximum length pipes can be extended to depends on the make and model. Check before you buy and make sure to measure the distance you need accurately.
  • Degree of bend – pipes can be bent to accommodate angles between the back of the toilet and the waste pipe. Some are available for 90 degree angles but care should always be taken when fitting pipes at angles to ensure the free flow of waste. Too tight an angle can make it difficult to flush waste away, causing blockages.

Choosing Soil Pipes

As with all plumbing works, parts should only be used if they can do the job. Flexible pipes can make connecting a toilet to the waste pipe much easier in confined spaces, but take care to ensure the free flow of waste when flushing, particularly for pipes that need to be fitted at an angle.
