So lets say this device is 5″ from the top of the tank WE ARE STILL WITHIN CODE BUT we can have an air space of 41/2 to 5″ “
Is it really with the USA code to have 41/2 to 5″ of air inside a tank of tepid water ? how do I spell legionella
Answer- YOU don’t as the TEMPERATURE if high enough to “POP” the safety would certainly kill ANY type of bacteria.
Safety = STEAM/vapor
Relief = Water/liquid
The code does say the probe shall be with in the upper most 6″ of the hottest water. if memory serves me correct I do not walk around with all the code books sorry
“DUH WHY NOT INSTALL an EXPANSION TAKE MATE? Do you know WHAT an EXPANSION tank is?”, Yes, but only from the talk here. We dont use them over here.
Answer: THIS is exactly WHY you have victims NOT clients Mate Your behind the times as usual.
Knowing you have VERY high incoming water pressure there is NO VALID excuse not to have either a Pressure reducer and or an expansion tank Mate.
“Now the water supply in many of these area’s were installed over 100 years ago.” Brisbane was opened as a free settlement in 1842 (thought I would give you something to bite on next )
Answer: Sir IM talking about Cast Iron water Mains and Aqua Ducts NOT hollowed out Trees or bamboo. We have Sewer piping from 1664 (Canal Street) if you care to compare CIVILIZED ways of living
“By installing a proper pressure reducing valve in EVERY home and building you have the following benefits.
1- Less demand on the pumping stations”
Hence water towers:
Answer Not necessary take 2.31 TIMES the pressure this is the height it will pump my good friend. NOT every building is a high rise and needs excessive pressure.
Look at my article TWO Views of high rise buildings on Loz’s site (Plumbviews Articles written by yours truly)
Bungie, it is also known SOME countries do have booster pumps in the basement/main floor to get water up to where it is needed.
Why should a city water supply be responsible to get water up over a 1/4 mile high (world trade center Or the Sears Building in Chicago)
“2- More available street pressure for more homes and emergencies
like fire hydrants”
Our street pressure would appear to be higher:
Answer: BUT at what price in erosion and the real possibility of major faults being created by undetected under ground leakage?
“3- Less pressure put on equipment like a water heater for example, why operate even close the max rating? DO you Drive your Dune buggy at max speeds ?”
HWS have cold water expansion valves. drive a dune buggy at max speed?? …. shit yeah
Answer: cold water “expansion” valves are prone to failure by just their design.
A lot of blokes use a 1/2 diameter C/W relief that becomes inoperable do to water impurities like calcium build up or other sediment. An expansion tank is just added insurance. Also thinking like a “plumber” we figure relieving capacity.
Knowing your excessive pressure conditions and knowing the limited relieving capacity of most C/W relief valves and KNOWING these devices are spring activated and the out let cannot keep up with the inlet Pressure Volume why use it as the ONLY safety when you have viable options?
“4- By being a professional and DESIGNING the flow rates as a REAL plumber would, you would be saving your victims countless amount of damage when a pipe should burst as the flow of water wouldn’t be as drastic as YOUR hit and miss design.”
Its the copper piping over there that we see all the posts about that are having pitting problems and leaking, not here
Answer: Have you taken water quality into consideration AND the AREA’S of the united States and the Population and the Chemicals my Government sees fit to dump into our water mains.
Fluoride, Chlorine and other great life form killers. Chlorine is poison, yet they allow more chlorine in water supplies then in swimming pools
Did you also consider the DROP in training in this country and how illegal aliens are now doing “plumbing” in the states with the most failures?
The copper/ cast Iron jobs I did as an apprentice (66-74) are still as good as new using copper tubing BUT the toilet parts did take a severe hit from the rubber parts disintegrating from the water supply being “treated”
I have customers, its not very nice to call yours “victims”
Answer: Wrong Mate anyone standing in 3 feet of sewerage OR 500 GPM flowing from a busted pipe inside their home is a VICTIM just like being hit by an IDIOT MORON driving a dune buggy over a blind hill not caring WHO is on the other side 
Ta Dum
Have a great week end mate
