Kenrich GP-2 Heavy Duty Grout Pump Single diaphragm, large 4.6-gallon hopper, built to last.

I am using it to repair stone wall foundations it's a little bit big for what I'm using it for but does have many good uses it does what it said it was going to do and is a godsend when you need it

Arrived quickly looked great didn’t last two days before it quit working it was cleaned after each use and reassembled didn’t work the second day only fruited one door frame without no response from the vendor or Amazon

It doesn’t work
