## Questions & Answers

**Q: Will this replace a t&p valve for a state industries model # es655dortgw water heater?**
A: The T&P valves for home water heaters are standard in most ways.  They have 3/4" threads for the inlet and outlet and 150 psi pressure relief setting.  The only difference is the length of the stem. The stem is the portion of the valve with the male (external) threads.  Some have almost no distance from the threads to the body of the valve and some have up to a couple of inches.  Look at the one on you unit and buy one with a similar stem length. A little too long is OK.  Too shot can be a problem.

**Q: My oem watts 100xl says it's a 8 inch probe...... haven't removed it yet to verify, but is this that long?**
A: It is an exact 100xl oem replacement.   Open with confidence.    Great product.

**Q: What is the length of the temperature probe?**
A: Sorry, I did not measure the length of the probe. The new valve was the exact same make and model of the leaking valve I replaced.  My water heater is a 50 gallon unit, the length of the probe would not have been an issue. The valve was a bargain compared to other sources.

**Q: What is the diameter of the threaded area?**
A: This valve has a 3/4" NPT thread.  A 3/4" NPT pipe thread has an outside diameter of 1.050 inches.
Hope this information helps.
