When A Basin Needs An Extension
Not every basin needs a vertical extension, the most common reasons for adding an extension are to to catch water splashing out of the pit and give the basin extra capacity.
Some pump systems can make a mess and splash water over the basement especially if they have leaky drain lines. This can ruin carpet, cause mold to grow, damage nearby electronics and ruin hardwood floors.
If your basin is too small and you can’t get a bigger pit you can and more capacity by adding an extension. As long as it is watertight adding an extension will allow your pet to hold more water before it overflows. Some crawlspaces and small condos only have small pets that do not allow for a larger pump so you have to be creative and add more room vertically.
How to Install
Installing an extension for your basin is easier than you might think. While each kit is slightly different they attach in a few different ways. The most common attachment styles are ‘secure fit’ models that snap over the exterior of your current basin, ‘screw in’ extensions that attach with tiny screws and ‘magnetic’ kits that attach using magnets inside and outside of the basin.
All of the kits costs about the same amount and can be installed in about 15 minutes without the help of a professional plumber. We recommend researching the style that has the best for for your basin so the seal is as water tight as possible.
You will also need to measure the diameter so your current basin so you get the right size – too small and it will not fit and too large it will allow water out through the cracks.
