Easy Order

Everything that was promised, was delivered including a very recent calibration report only two weeks out from date of purchase. The pocket knife was a nice touch also, will look at purchasing other items in the future.

Great Test Rig

This kit is much better than my old test kit (Watts TK-9a) and ordering, delivery everything was a breeze. I won’t hesitate to order from Backflow Supply again in the future.

Previously ordered a Mid West 845-5 backflow test kit. I received constant updates and got my gauge in a timer manner! I just wanted to say thank you. The complementary note pad, pen and knife were awesome! It's the little things that make a business a good business! Thanks and good job!
