T & P valve needs half turn more

I just installed the T & P valve on the top of my new water heater. But it's pointing the wrong way. I need to rotate it half turn more. I have 3 wraps of teflon tape. Would it be ok to add more wraps of tape or less wraps so that I can get the valve pointing the right way? Thanks

You either need to tighten it another half turn OR you overtightened it by a half turn. I'd remove it, remove/replace the teflon tape and try it again. You probably should have just stopped a half turn earlier.

How big of a wrench were you using when you installed it? An eighteen inch wrench is not too big and you do need to put a bit of muscle behind it.

Thanks for the replies.

I was using a 12 inch wrench. I gave it another half turn and now it's pointing correctly. Feels like it could torque some more, but stopped. Did not want to risk over torque the T&P valve. I did not remove and reapply new tape. Should I have? Have not begun to fill tank yet.

Thanks

A twelve inch wrench would really need some muscle behind it. I think you should be okay.

That wouldn't be necessary unless you removed the T&P relief valve. I agree with Furd, I think you'll be fine.

No plumbers tool kit is complete with out a 24" long piece of 1" steel pipe for when your wrench isn't long enough.

Filled the tank and fired up the water heater. Plenty of hot water and no leaks. Should I snug up on the flex line water connections after a few days or leave alone?

You could give them a snug if you like... Sometimes things loosen up on hot side from thermal expansion and contraction.
