Customer request to check integrity of drain, where it goes. Gave option for diagnostic. Unable to give camera inspection due to size of drain. Ran super vee down to see if it would go through, super vee did make it through. I pulled the super vee back and then tested by hooking up a hose to the nearby water heat and running water down the drain, floor drain is draining properly. *Note there is no warranty or guarantee. Thank you for choosing CPI plumbing and heating.
