Hello,

I was hoping for a little help,I have a 50 yr. old house in california with the water heater in the basement(original location). A inspector told me I need 1. to raise it 18" off floor...theres no way I only have like 10" from top to floor joist. and 2. plumb the T&P to the outside.
I have the line 6" off floor not sure how to get outside..have deep sink on other side of basement that I guess I could run it to but its like 15' away and it would have to be run in the joists.

any help would be appriciated

Your best bet would be to get a plumber around and check that out. I have never heard of having to raise a hot water cylinder of the ground by that much if at all and your temp/pressure relief should really be piped to where it cant burn anyone if it's goes off. We used to pipe them through an external wall and use a return elbow and point the pipe back toward the wall so that if there was ever a issue you would see the water coming from it and no one would get burnt from heated water.

And what was the reason to raise it? When installed in garages they should be 18" off the floor because of potential gas fumes

To many things don't make sense.

What kind of inspector was this?
Why was the inspector there?
What else is going on in the basement?
When was the water heater installed?
Who installed the water heater?

I'm not a plumber or inspector but I have no idea why an inspector told you the WH had to be elevated unless you basement is a garage.
The book had this to say about the temp relief piping

2006 IRC P2803.6.1 Requirements for discharge pipe. The discharge piping serving a pressure-relief valve, temperature relief lve or combination valve shall:
1. Not be directly connected to the drainage system.
2. Discharge through an air gap located in the same room as the water heater.
3. Not be smaller than the diameter of the outlet of the valve served and shall discharge full size to the air gap.
4. Serve a single relief device and shall not connect to piping serving any other relief device or equipment.
5. Discharge to the floor, to an indirect waste receptor or to the outdoors. Where discharging to the outdoors
in areas subject to freezing, discharge piping shall be first piped to an indirect waste receptor
through an air gap located in a conditioned area.
6. Discharge in a manner that does not cause personal injury or structural damage.
7. Discharge to a termination point that is readily observable by the building occupants.
8. Not be trapped.
9. Be installed to flow by gravity.
10. Not terminate more than 6 inches (152 mm) above
the floor or waste receptor.
11. Not have a threaded connection at the end of the piping.
12. Not have valves or tee fittings.
13. Be constructed of those materials listed in Section P2904.5 or materials tested, rated and approved for
such use in accordance with ASME A112.4.1

Notice all those rules but it says nothing about the discharge pipe being PVC..so it can snap at the when discharged and scald everyone nearby...

Nice way to high jack a thread for your petty little fight.


Back to the OP concerns< I would call your local plumbing inspector and have him / her clarify what the code is for your water heater. Something just does not sound right.

The inspector is totaly wrong or being a dick. The only reason a water heater should be 18" of the floor is if it's located in a garage or any place containing flammable liquids.
