The sump pump pit liner - How does a sump pump work?
In this article we will look at the sump pit liner and its role in "How does a sump pump work". The sump pump pit liner is the home for the sump pump. The importance of sump pump pit liners tends to get overlooked when installing a basement sump pump system.
Sump Pump Pit Liner - the 5 gallon bucket method
Many sump pump pit liners are just 5 gallon buckets with some holes drilled in the sides or an open hole in the floor with a pump thrown in. This approach to installing a sump pump pit liner is very common. The use of the 5 gallon bucket method does ultimately pump water out of the basement.
However, the 5 gallon bucket or open hole approach is not the best, nor it is the right, solution.
Four Main Components of an Ideal Sump Pit Liner
A good sump pit liner has four main components. These components are a sealed lid, pump stand, erosion control and large holes.
Nothing can fall in and clog the pump
Prevents soil gases from entering the basement
General safety - People & Pets
Solid sides (No Holes) against the foundation
Not too deep, deeper is not better
These two items can lead to soil erosion under the foundation walls and floor if not incorporated into the sump pump pit liner
Larger holes allows water to flow to the sump pump faster
Larger holes do not get clogged
Small holes reduce flow and makes the sump pump wait for the water to fill up before it can pump. Also known as short cycling
There are a handful of companies that have designed a sump pump pit liner that incorperates all of the four features of an ideal sump pump pit liner. In the Northeast, I recommend Grate Products. They carry a great line of basement water control products. Grate Products also has a strong certified contractor program if you need something installed.
