Valterra SS02 Extension Hose for SewerSolution System - 10'

Hard and expensive lesson to learn that Walmart "Marketplace" is not as reliable as Amazon for return policies. Makes me very leery now to shop online at Walmart even though that's what they are pushing us to do. Lady at the customer service (kindly) made me aware we have to check the return/non-returnable features of every purchase: if the item is shipped by a "partner vendor" then it is non-returnable! I have no idea if this product "fit" or was a good value or not. We purchased it along with the Septic Solution with the intent to replace our previous macerator, but did not actually need the additional 10 feet this hose would have provided. The Septic Solution did not work to our satisfaction, so we (successfully) returned it. However, I had missed the small print that THIS particular product was NON-REFUNDABLE -- which means I now own a $43 section of otherwise unusable hose even though it was never used or even removed from the packaging. So the (USED) Septic Solution itself was returned without any questions (!!) but the UN-used 10 feet of hose extension was NOT.
