I found that water heater relief valve drain can not be in to pan but can it be in a bucket?

I agree with Mark it is simple stuff but we gotta meet that code or look bad doing rework. but if the code book is on your side you have a little peace of mind

The way I look at the WAGS valve is, the T&P valve should never open unless you test it (and then, you can direct the water so it won't activate the valve). The advantage is, it does not require any power, immediately shuts the water off, and if it's a gas WH, can disable the burner so it isn't trying to heat all of the water that is being replaced from the leak. The more complicated it is, the more likely it can fail...this is pretty simple activation...the same thing that makes a life preserver inflate as used in an airplane. An alarm won't do you any good if you're out of the house at work, or if the power is out, a typical powered shutoff valve won't either.

Think of it as an insurance policy. You hope you never need it. Maybe I've been lucky, but I've not had a situation where a WH failed enough to cause any damage. I don't sell them or get any benefit, I just think it's a novel solution that would have solved that situation Mark talked about and the renters. They'd have not had any hot water, and things would have been fixed...lots cheaper than a $900 water bill.

You realize that the code book is not the holy bible and actually most customers have not got a clue as to
what the code actually is.... and most inspectors dont really know what the code is....... many times I explain to them as to what is right and what will pass.... and you got to just let things slide without quoting the code book like you are reading scripture....... Sometimes I can see right through a guy when he starts quoting code to me because that usually means he is in-experienced.....and is leaning on the code like a crutch....



This is not space shuttle technology we are talking about here ..... it is just basic common sense
sometimes you have to go into that grey area with the code to actually do what is best for everyone and WIN....

Can you dump above the pan?

This what we have been installing NOT Cheap BUT it costs less then a law suit

Mark, I was only telling the code heights for a tand p it will get you called here for correction .

I like that Sylvan, My Code and UPC ( curious code is UPC with Washington amendments) and varies significantly with regard to Tand P discharge height . but always like to hear how things are done in other areas .
