Backflow Troubleshooting Quiz
While subject trying out the check valve of a strain vacuum breaker, water keeps to waft from
the # 2 take a look at cock . How do you continue ? - ANSOpen the bleed off valve till the
flow slows to a mild drip.
Well discipline trying out the primary check valve of a double take a look at valve meeting,
water keeps to drift from the site tube. How do you continue? - ANSObserve reading on
gauge (first step). Open excessive side of bleed valve (2nd step).
While area testing the check valve of a spill resistant strain vacuum breaker, water maintains
to drift from the vent valve. What does this imply? - ANSNumber 1 shut off valve is leaking.
While discipline trying out the differential stress alleviation valve starting factor of RP, it's far
observed that the shut - off valve # 2 is leaking . How should the transient skip hose be
connected to compensate for the leak? - ANSTest cock # 1 to check cock # 4
While area trying out the second take a look at valve of a discounted strain principle
meeting, excessive aspect strain is applied thru take a look at cock # 4 and the gage
analyzing starts offevolved to boom. How do you proceed? - ANSClose the # 2 test cock.
While discipline checking out the differential stress relief valve establishing factor of an RP,
the high facet manage needle valve is open, and the low aspect manage needle valve is
open 1/four flip, however the analyzing on the gauge will now not decrease to the comfort
valve commencing point. What does this suggest? - ANSNumber 2 shut off valve is leaking
What are appropriate area take a look at readings for a nicely working double test valve
assembly? - ANSCheck valve number one: 1.0 PSID and above/ take a look at valve
number 2: 1.0 P ID and above
When testing an RP, upon final the wide variety 2 shut off valve and the excessive and low
aspect bleed valves, the gauge studying drops and differential pressure alleviation valve
starts to discharge. How do you proceed? - ANSRecord the number one test valve is leaking
and stop the test.
While subject trying out the number one test valve of a DC, water keeps to go with the flow
from the website online tube. What is most possibly to be the reason of this situation? -
ANSShut off valve #1 one is leaking.
While area trying out the differential strain comfort valve of the RP, what gauge analyzing
indicates a failure? - ANSLess than 2.0 PSID
While area testing the air inlet valve of a strain vacuum breaker, the excessive side bleed
valve is opened 1/4 turn and the gauge reading will not drop. How do you continue? -
ANSClose the high aspect bleed valve, then open the number 1 take a look at cock.
