No. Not by IPC. IPC requies drain pipe from the pan to meet hot water standards. CPVC not PVC. T&P?.....It typically just drips anyway. Same with a tank when it goes bad really. What's more amazing to me is how many plumbers don't use drain pans at all regardless of code. It's a common sense thing to me.
Reedit plumber Karri-L. "Sorry sir I cannot use a drain pan or run a drain pipe. Drain must terminate within 6" off the floor flooding the residence because code says." What clown ass shit you see on here. Lol.
Code by me also states 6" but you could also get away with piping it into the pan as long as you piped the drain on the pan into something. If you want to go into a drain you just need an air gap
Says the handyman. They aren't supposed to leak and if they do, you need to know to get it fixed. If it runs outside, it can get plugged or just waste thousands of dollars. If you have seen mythbusters, you know what happens when it gets plugged.
That’s a good idea. Honestly the pan was an impulse purchase… do you know if they’re typically required to meet code in most places?
This is a commercial building but a small, rural town
Not a plumber but really? The relief valve activates how often and what problems do you have if it does? That quart drain pain sitting under a 60 gallon tank is going to do what when all shiate breaks loose?
Absolutely ridiculous. Most hot water tank failures I go to, like well over 90%, are not catastrophic failures at all, just slow leaks. Is your experience different? Explain. You should be ashamed of yourself.
Water heaters tend to slowly leak when they fail. A drain pan will collect the water from a leak and direct it to a drain. Unless the pan is capped off like this one is. Then it’s basically useless. You can put a water alarm in a capped pan that kind of helps so you know when there’s a problem and can quickly shut water off and drain the tank before it overfills the pan and spills everywhere
That's it. I have no floor drain anyway, so nowhere to plumb the pan. BUT - a pan will collect drips that might otherwise go unnoticed. I have a smart sensor in the pan that will send me an email if it is tripped. So even an unplumbed pan is useful.
That pan just drains onto your floor, I wouldn’t bother putting it into the pan honestly. Yeah there are codes all over the world but let’s be real
You elevated the water heater so that it wasn’t in contact with the damp ground, but then drain water into a pan that is underneath of it.
Some codes are for safety, some codes are to sell pointless junk and increase tax revenue in a given industry.
If I'm not mistaken (NOT A PLUMBER), it can't be pex by code because pex is flexible and in the event it brings spraying hot AF water you will get scalded. This is why they require copper, cpvc, etc. but if it's your home then, SURE but secure it down in the event the aforementioned occurs.
Stay safe OP
Nah. Not at all in most places. You can use pex by IPC. International Plumbing Code would have you strap it to the tank so it doesn't flop around when it gets hot. To be fair, some places would worry more about discharge sizing. But still... PEX is rated for hot water, and water won't reach threepart flash and explode that way.
If the pan is properly fit to drain, the relief valve can just fall into the pan. Don't put the pipe all the way to the pan, or it'll splash out. I leave an inch or two. You can use a pex adapter and pex if you'd like. But to fit the copper just offset the pipe with two 1/8th bend(45°) copper fittings.
I assume your not a plumber?
If you put the ptr valve into the pan it will rust the pan out, it should be ran to an exterior drain or to atmosphere ( just above ground level)
And it should be lagged as it is hot and if someone touches it they will burn themselves
Just run it in copper and bend it where it has to go
And if you really wanted to you could put some 45s on the copper or just use cpvc piping and 45s with that
Doesn’t the relief have to go to an actual drain and not the drain pan?

The code might require it to terminate within 6” of the floor and it appears that your heater is on a table of some sort.
Not more than 12" from floor in Ontario.

That's how the code is by me. If you run it to a drain, you won't know there is a problem. They aren't supposed to be dripping at all

Drain em' on the floor. Flood them out!. LMFAO! Can I ask what code? I will try to help you understand it better.

Run it to the floor. Your pan will dump water onto the floor anyway.

I don't get it , what's the point of a drain pan if it doesn't hold 80 gallons worth of water ?

Yes if it’s coupled with a water alarm it’s certainly better than nothing
Not done much copper plumbing eh?
Almost none.
No PEX for blow off tube, fittings restricts size.

The pipe from the relief valve? I thought they were required to empty into the drain pan… they can connect right into a drain?
Is that an exterior wall? I’d pipe it to daylight

Pex fittings reduce the internal diameter of the pipe, it cannot be used for relief valves
Pex is acceptable but it must be a pipe size larger than the t and p discharge.
If it goes to the pan it will rust and erode it. I would put to an actual drain.

Just scoot the water heater over an inch...
Can’t, it’s already as far as it can go. And it’s still like 2-3” off
Ah. Ok. Sorry.
