The Original 1-valve Differential Presure Gauge / Backflow Test Kit

Why choose the 1-hose test kit?

Simpler to use

Prior to the advent of the ASSE 1-hose RPZ test procedures, no matter what you did, if you were testing a Reduced Pressure Principle Backflow Preventer (ASSE 1013) you would need at least 3 valves, 5 valve often being even more popular. The amount of opening and closing valves required often becomes cumbersome and wastes time in the field and allows more room for error. With our kit, you only have 1 valve and 1 hose to work with.

Fewer Components / Fewer Problems

With Kruger's Training Academy - Calibration Services - we have a lot of experience calibrating and repairing backflow test kits. When you have a leaking valve, fitting, hose, etc., it makes the gauge unable to be calibrated and requires repair. With our test kit, there are much fewer things that can be damaged.

Reputable Construction

The main body of the gauge is the Orange Research 1516 with a 0 - 10 PSI range and 2% or 0.2 PSI accuracy. This is an industry standard and the base differential pressure module used for the Watts TK-9A, Buffalo Backflow,most Accugage products,

How do you use the kit?

Included with your order will come laminated waterproof sheets with illustrated instructions of how to test the Reduced Pressure Principle Backflow Preventer Assembly (ASSE 1013), Double Check Valve Assembly (ASSE 1015), Pressure Vacuum Breaker (ASSE 1020), and the Spill Resistant Vacuum Breaker (ASSE 1056). The instructions are based on the ASSE 5000-2015 Appendix F.

We have video examples and instructions available on our YouTube Channel - You can also download the instructions in pdf HERE - Keep in mind since it is a 1-valve 1-hose kit, the steps will be slightly different than the 3-valve ones, but all is in compliance with ASSE 5000, therefore shoulacceptable to jurisdictions according to all local plumbing codes and laws.

Kruger Instruments - TK-1 Package

$550.00

$550 is the price initially charged. You pay the $550 via credit card, the shipping is included but sales tax must be assessed. We then keep the sales tax and refund the difference, so for example NYC is 8.875% so you pay $550, and are assessed $499.99 for the product and then $44.37 in sales tax, so you would be charged $544.36 and refunded $5.64 via PayPal upon shipment. This is the only way I see to have online payment available, you can also pay by phone at 917-887-5613. Once paid, you fill out an order form below
