Random thought....
Why do we call it a Water Boiler when we are actually trying to avoid boiling water?? Think about it. Steven Wright would be proud.
Just a thought pointed out by John Siegethaler in the Supply House Times June 2012 Edition.

Help I have more parts stuck in my Backflow
In a follow up to my last post about Hydraulic Lock here is another tip on stuck backflow parts. If you ever come across an Ames 2000/3000/4000/5000SS Series backflow (which is the same as the Watts 774 and 994 Series) that the checks are stuck in here is another trick.
The problem is the stainless steel body is a softer metal than the iron valves and can become "twisted" in line. The body gets torqued just enough to stress the threaded connection of the plastic checks and you can't unthread them. To alleviate the stress "pop" the bolts or unthread them just enough to loosen the connection. There is no need to totally take the nut off we are just removing the torque not the backflow. Now attempt to unthread, many times this makes all the difference. ***Remember to tighten the connections when the repair is complete.

Help I can't get this part out of my backflow preventer!
If you have ever been working on a Backflow Preventer and couldn't get the parts out you may have encountered what is called HYDRAULIC LOCK. What is that you say? Well think of a suction cup being pressed down against a seal, the pressure creates a seal and the suction cup holds tight.
If you are dealing with a check that will not pull out it may be the same phenomenon of a pressure (think back pressure on a backflow) creating a suction between either a closed valve or another check seal. The way to alleviate the vacuum is to open the test cock in the zone ahead of whatever part will not budge to let air into the zone and voila your part is free.
