The relief valve is supposed to have a 3/4 line leading away and down to 9" from the floor . That said if it is loose, tighten it slightly and then run piping away from the controls.
SOURCE: Relief valve constantly releasing water.
lower your thermostats a bit. If your temperature is set to the hottest setting, then chances are no relief valve will do
SOURCE: pressure relief valve
The pressure relief valve only leaks when there is excess pressure in the system, possible causes could be excessive static pressure, overheating, faulty pressure vessel or undersized pressure vessel.
SOURCE: relief valve leaks on new install with just the cold water on
is the relief valve new?if not it should be,and yes the new one could be faulty from factory.also might be some debris caught up inside.
Testimonial: "Rheem did send me a new pressure release valve that did not leak."
SOURCE: I think my relief valve broke because my water was
This is one possible solution. Not knowing the type of plumbing pipes you have or where the leak was makes it hard to give you a solid answer. Some people will open the t&p valve to aid in draining water out of piping to facilitate repairs. There is a small lever in the center of the t&p valve that should be at 90 degree angle to front surface of a valve mounted on side of tank. If it's straight out it is open. Push down on lever to close it. If it was opened and then closed it may not have shut off completly due to mineral build up around valve seat.If it is open then close it and turn water supply back on. If it is closed you can turn water supply on and using wooden hammer handle or other light tool tap directly on center of valve. Do not hit it very hard. If it has been opened and failed to seal you should see a reduction of flow rate fromt&p valve. Either way youshould have t&p valve replaced as it should olny open due to extremely hot water which also will cause increase in pressure. Hope this helps. Thanks.

Water heater should be set in a drip pan.
Otherwise, put 1 gallon bucket under TP release pipe to catch water.

When you say relief valve, I assum you are talking about brass valve located on top of tank or near top of tank. This is TP valve and a pipe connects to this valve and runs down to within 6" of bottom of tank. TP valve has a small lever on it.
If you are talking about tank drain valve located at bottom of tank, then add a comment.
Following information is for TP valve.
Dripping TP valve can be caused by 3 different thing:
1) Obstruction inside TP valve. Open TP valve for a moment to flush away
particles and slowly lower lever back down. See if water stops
dripping, if not, then replace TP valve
2) Defective TP valve: replace TP valve. Turn off electricity to water heater. Let heater cool for several hours so you do not get scalded. Close shut off valve located above tank on cold side. Open tub spout to relieve pressure, open tank drain or open TP valve and empty water below TP valve level. If TP is located on top of tank, not much water has to be drained. Tank is under press when hot, so be careful. Put teflon tape on new valve and install with big pipe wrench by turning clockwise until TP valve is very tight.
3) Overheating tank. TP valve is temperature-pressure valve. If tank water is over 150 degrees, the TP valve starts drizzling hot water to relieve tank pressure.
Lower tank pressure two different ways:
a) turn down thermostat

b) install expansion tank on incoming cold water line
