The quick answer: nope. Bottom drains aren’t necessary under most conditions, so they can be a waste of money. It’s important to know whether or not you need one because it can make a big difference in the health and look of your pond. Keep reading to find out why or why not.
What exactly is a bottom drain?
A bottom drain is simply a drain in the deep end of the pond. It removes debris from the bottom of the pond to the filters where it can then be removed. Your pond is therefore supposed to be cleaner and clearer from using one. Of course, for it to work properly, it needs to be cleaned regularly (sometimes daily, depending on the amount of debris falling into the pond.
A pipe will need to be run under the liner. This means a pathway must be dug out so a hump doesn’t show. A hole is then cut in the liner and the actual drain is installed.
It’s a technical process, and adds quite a bit of expense to the construction, so is it worth it? Not to mention, it’s almost always a potential leak issue because there’s been a hole cut in the liner.
Pro's & cons of a bottom drain in a pond
What does The Pond Gnome think of bottom drains?
We don’t need them.
The Pond Gnome builds sustainable ecosystem ponds that don’t need bottom drains. The ponds we build are typically less than 4′ deep, which means a bottom drain isn’t needed.
We do, however, often install intake bays in deeper Koi ponds to add to the circulation and ease of maintenance. They’re much easier to install, and don’t require us to cut a hole in the pond liner, which is always a potential leak issue.
