Choosing the width of the baffle should match the inside diameter of your sump structure.
Choosing the height of the baffle is accomplished by measuring the distance from
the bottom of the outlet pipe to the top of the highest inlet pipe and then add 18 inches.
Then choose a baffle that is at least this tall.
MnDOT Reports the SAFL Baffle has saved Minnesota Tax Payers more than $8 million dollars in the last 3 years and
expects to save another $26 million over the next 10 years.
