Can I fill a Bravo Double Wall sump with another manufacturers Propylene Glycol solution?

A: No. Our glycol is a light red color and is the only fluid allowed in our sump walls primarily to assist with troubleshooting and identification in the field. The exception is water if the sump must be emptied of glycol and flushed clean but water or colored water may not be used for continuous monitoring within our sump interstice. Additionally, other manufacturers may add other chemicals or inhibitors to their fluid in different concentrations which we do not test for or certify.
