Why include a drainage hatch in the floor of your greenhouse?

Having a new greenhouse built is an exciting project and once completed, it will add a new level of space and comfort to your home. A greenhouse will also add value to your property and can be a great selling point for any home. Once you’ve decided on a greenhouse, there are a few important things to keep in mind before you give the go-ahead to start laying the groundwork.

Building on clay soil, for example, has to meet certain safety criteria and installing a greenhouse near shrubs or trees can mean higher costs due to the need for a deeper foundation. Another key consideration is whether there are drains or sewer inspection covers on or near the proposed greenhouse site.

Most homes built since 1939 will have their own private sewer system rather than being connected to the one owned and managed by the Water Authority, but you should verify this before any work begins. You have a legal obligation to get approval from your water authority, before you start building, if the greenhouse is within three meters of any public sewers.

If you have to build the greenhouse on top of an inspection cover, you must replace the existing one with a sealed cover so that no gases or odors escape into the greenhouse. In any case, if you cannot avoid building the greenhouse over pipes or drains of any kind, it is essential that you make sure to include a hatch or hatch under the greenhouse to allow access to the pipes underneath.

A hatch or hatch can save you a lot of hassle and hundreds, if not thousands of pounds in cost, if you have to break the floor or drill a hole in your new greenhouse to access a blocked pipe or drain underneath. It sounds simple enough, but it is a key detail to include when planning a greenhouse.

Unfortunately, more than a few people have found to their cost that installing a greenhouse over pipes or drains without installing a hatch can turn into a nightmare, especially when faced with the problem of a blocked toilet with no access to the pipe. .

So be sure to bring this point up with your greenhouse company when planning where to build and make sure that the correct steps are taken if necessary to avoid such problems in the future.
