Tip & How-To about Plumbing

What is Backflow or R.P.Z.

Why get my Backflow device tested? Each Backflow device must be tested and certified at the time of installation , then annually once per year of the entire life of device.
Testing the device is important to insure safe clean drinking water, testing the device once a year is to insure the backflow is working properly.
Who can test a Backflow?
Only a C.C.D.I. Inspector can test backflow device‘s. Note: not just a licensed plumber, C.C.D.I. is its own license.
Once a person has become a licensed plumber, they are eligible to apply to take a C.C.D.I. course .
After completing the course, one becomes a C.C.D.I. Inspector.
Backflows that aren’t annually tested once a year can not guarantee clean safe drinking water to its users.
What is Backflow?
Water in a pipe can flow in either direction, Flow is the intended direction of wich the water should flow under normal working conditions. BackFlow is the flow of water in the un-intended direction.
Backflow can happen when unequal pressure causes the flow to be pulled back the opposite way intended, causing non-drinkable substance such as chemicals or contaminants from getting into the drinking system.

watts backflow prevention device 009M2 relief valve spraying continuously


As a Backflow Tester, I have to recommend calling a certified Tester with experience in repairs. There are a few thing that could cause this such as debris stuck on the #1 Check disc (which usually means repair parts) or a nick on the Relief Valve seat. The rv seat is stainless steel and just pops in the bottom of the valve with an o-ring seal but unless you have experience at this I suggest you leave it to a professional as you could easily damage other parts or reassemble improperly.

noisey waterpipes what is this?


It is referred to as "water hammer" It means that there is air trapped in the pipes
and causes chattering (it will also rattle loose pipes in walls). Best option is to
have a "pressure tank" installed at the water heater to reduce this. Hope this is helpful.

Will someone please walk me through the steps to calculate a mortgage payment on the BAII PLUS TEXAS INSTRUMENT. Please be specific. Thanks.


For a thirty-year, $100,000 mortgage at 8% annually, compute the monthly payment:

2nd [CLR TVM] ( clear the time value of money registers )
3 0 * 1 2 N ( thirty years at twelve payments per year )
8 I/Y ( 8% annual interest )
1 0 0 0 0 0 PV ( $100,000 mortgage )
CPT PMT ( compute payment )

You should see -733.76. The negative indicates payment, the amount is $733.76.
