Mistakes to avoid when installing plastic drainage pipes

Installing plastic drainage pipes yourself for your underground drainage can be cost-effective and highly reliable when done properly. While you don't need to be a plumbing expert to do the job right, you do need to make sure you avoid these three common mistakes:

Failure to properly plan

As with any DIY job, and indeed anything in life, the secret to laying plastic drainage pipes properly revolves around you putting in the necessary time and effort to make sure you've thought about every aspect of the job in advance before you even pick up a shovel.

For example, do you know the exact course of plastic pipe you intend to lay? Have you considered what blockages or difficulties you might encounter along the way? Have you accounted for where the water will actually drain away to in order to avoid rotting your foundations?

Not notifying local utility companies

Before you start digging here, there and everywhere, make sure you put in a phone call to your local water, gas, and electricity suppliers to make sure you're not going to inadvertently go dislodging a water main or putting your shovel through an electricity cable.

The dangers of unforeseen cabling are obvious, in as much as you're at best going to black out your property and worse get intimately introduced to more voltage than you would ever like to, but there's more besides that you need to be considering. That's the fact you'll almost certainly going to be financially liable for any damage you do.

Neglecting to keep to the right fall

Keeping your drainage water flowing smoothly is going to ensure you don't have to deal with blockages and needing to wait for an age before the water actually drains properly. The way you do this is by making sure you're laying your plastic pipe to the correct fall, which is general 1 in 40. There is a product on the market called "Pipefall" which will make installation easier.

You can't expect water to run up-hill unless there's far more pressure than you're ever likely to have in your drains, so if you're laying your drainage pipes at all angles you're just inviting problems ranging from backups, breakages, and pools of stagnant and stinking water.
