2023 forest river Salem light hot water pressure relief valve

I have a 2023 forest river Salem light and my relief valve was leaking. So I need to buy a new hot water pressure relief valve. Iím at Home Depot and I do not know which one I need does anyone know the psi rating for my camper so I can buy the correct one?

Most of the 3/4 " valves I see are 150 lbs.
They also have a probe.

Just out of curiosity, have you tried opening and closing the valve several times to see if it reseats? Seems like a pretty new RV to have a leaky valve. But anything is possible.

And if the valve really is bad, I would take the old one out and then find an exact replacement.

You may experience water weeping or dripping from your water heaterís Pressure and
Temperature (P & T) Relief Valve when your water heater is operating. Water weeping
or dripping from the P & T Valve does not always mean the P & T Valve is defective.
As water is heated, it expands. The water system in a recreational vehicle is a closed
system and does not allow for the expansion of heated water. When the pressure of
the water system exceeds the relieving point of the P & T Valve, the valve will relieve
the excess pressure.
Suburban recommends that a check valve not be installed directly at the inlet to the
water heater tank. This will increase weeping of the pressure relief valve.

Do not remove or plug the relief valve.
One way to reduce the frequency of this occurrence is to maintain an air pocket at the
top of the water heater tank. This air pocket will form in the tank by design. However, it
will be reduced over time by the everyday use of your water heater.
To replenish this air pocket:
1. Turn off water heater.
2. Turn off cold water supply line.
3. Open a faucet in the RV.
4. Pull out on the handle of the Pressure Relief (P & T) Valve and allow water to flow
from the valve until it stops.
5. Release handle on P & T Valve - it should snap closed.
6. Close faucet and turn on cold water supply; as the tank fills, the air pocket will
