*

I am wonder if anyone has ever heard of a water heater imploding because it walk not have a vaccuum relief valve mounted on it...?? This is a new one ~ above me.I to be just having a conflict on an additional forum around this issue. Someone mounted one top top the peak of a brand-new water heater and it tripped open and flooded the end someones house to the track of $60,000... The plumber proclaimed it was code to have one.... Yet their to be no capture drain or anything to protect against the point from flooding the home.so this renders me wonder how many areas of the USA is this vaccuum relief valve forced on a water heater?? it is not forced in Indiana.... Reportedly it is required in brand-new England.also has actually anyone actually seen an imploded water heater in their plumbing travels??...anyone obtained a snapshot of one

Technically the newer dip tubes have to negate the require for a different vacuum breaker, but here in NH, most examiners will fail the project if they don"t check out one. I have seen number of Bradford White water heaters implode. I don"t think it had actually anything to execute with the vacuum breaker or lack of. Ns think they to be just bad tanks.
All vacuum Relief Valves are used for in water heater/tank applications to automatically enable air to go into into the piping system to prevent vacuum problems that can siphon the water native the system and damage water heater/tank equipment. Never heard of an implosion , they room used here to keep the water indigenous siphoning out of an overhead electrical water head and also burning increase elements.

The Rheem marathon w/h have to have them. The plastic tanks will expand because of pressure there is no problems. If you eliminate the vacuum breaker and also drain the tank it will crack that everyone.I had actually a customer try to adjust the elements on one. He tried to air lock it, but that did not work as result of the vaccum breaker. He eliminated the vb and also replaced it with a tee, with a cap. He managed to airlock it and replace the element, however it led to the tank to crack.It additionally voided the warranty.

yes, over there is a hole in the dip pipe that stays clear of a water heater from siphonage, and the need for this device seems come be more of a "make work" point to me..also , i wonder that gets come pay for the damages ifone fails and floods the end the home..a few weeks under the road??Has anyone ever before seen one fail and flood the end a home??So when you install one top top the heater perform you try to figure out a means to run some sort of catch drain indigenous it come a pan or drainpipe ??? or perform you simply gamble top top it and hope it never floods someone out?? simply asking the inquiries for my own education

Sounds favor this plumber demands to get the manufacturer that the VB involved and also find out why the VB fail in the an initial place. We have actually been putting them in for years here and I have never watched one fail prefer you are talking about. Why would this VB have actually failed uneven someone had actually shut the thin down after the new heater and also VB had actually been mounted , who shut the water off and didn"t examine everything out as soon as they rotate it back on or did the fail if the water was on ?
Seriously despite I have actually only ever seen really old vac breakers drip and corrode. I"ve never seen one blow out. If the water heater is in a perfect area i install a drainpipe pan and also floodmaster anyway.

He regulated to airlock it and replace the element, but it led to the tank come crack.It likewise voided the warranty.

I am brand-new to this principle I have never heard of or checked out one on a heater. Excuse my ignorance, however can who please define how a hole in the emboldened tube breaks the vacuum as soon as it is totally submerged, I"m not expertise this concept. It seems to me if the tank is imploding because of a vacuum/siphon the manufacturer must be making the tank more powerful period. The tank works off of a siphon if it stops working under normal procedure it have to be on the manufacturer. This must be a non-issue in my opinion. Perhaps I"m missing something. Again excuse mine ignorance, can someone clean this up for me??
The vac breaker is there to limit back siphoning that the water heater. If the tank starts come siphon out the inlet, the feet in the height of the dip tube will break the siphon since air will certainly come in. Ns don"t think it has actually anything to carry out with avoiding tanks from imploding.

I am brand-new to this principle I have actually never heard of or seen one top top a heater. Excuse mine ignorance, but can someone please describe how a hole in the dive tube division the vacuum as soon as it is totally submerged, I"m not expertise this concept. It seems to me if the tank is imploding due to a vacuum/siphon the manufacturer should be do the tank more powerful period. The tank functions off the a siphon if it falls short under normal procedure it need to be on the manufacturer. This have to be a non-issue in my opinion. Possibly I"m absent something. Again excuse mine ignorance, deserve to someone clear this up for me??
When you revolve the water off to a building to fix a leak on the cold side, if the water heater is above the area you are working, it will siphon the water out of the tank via the dive tube as result of a vacuum being on the mechanism from you cutting the pipe and the water draining. In Houston our tanks are generally in the attic for this reason they call for vacuum reliefs below for elec heaters. Together stated prior to though, many dip tube now have actually the hole at the height to protect against from siphoning past the optimal of the tank in a vacuum situation. If ns am working on say, a 2 handle bathtub faucet, (with a water heater located above the faucet) once I remove the cold next stem, after ~ the early residual water drains, the water heater starts to drainpipe or siphon, really, via the cold side and now warm water is is steadily draining out of the tank through the cold side of mine faucet. It won"t protect against until girlfriend shut turn off the valve or the water level drops below the bottom of the dip tube.I constantly shut turn off the water come the tank when I"m working on the water lines since most tanks have no vacuum relief and also many absence the vacuum relief dip tube. It conserves a many hassle. Whereby water heaters are situated in a basement or crawl space below the water lines, there"s rarely an worry with this.And I have never heard or seen a water heater implode. I"ve seen plenty increase or explode. Its new to me.
