It is in the fountain in one of the front corners of the grounds outside. I think it is the right corner but I'm not sure which corner. You will need the fish food and poison to get it. They can both be found in the manor. To get outside, go through the tiled room with stairs in the middle ( do NOT go down the stairs, the vampire is down there for the vampire slayer quest) and take the door throught to a room, that has a door that leads outside! The fountain is marked not with a water symbol, but it looks like a grey blob. Good luck!
pressure relief valve relief the excess pressure which is developed in the syatem, while pressure reducing valve reduces the pressure and supply it to the system.
no pressure release valve
Your pressure relief valve may be leaking due to high pressure in the system or a faulty valve. To fix it, you can try adjusting the pressure settings or replacing the valve if it is damaged.
A pressure valve is usually installed on water systems to prevent excess water pressure from destroying fixtures or other plumbing components. When the pressure exceeds the valve ratings the valve opens and releases water/pressure from the line.
Too much pressure or defective valve.

Is the pressure reducing valve leaking in your system?
Is the pressure regulator valve leaking in your system?
To adjust the pressure relief valve, locate the adjustment screw on the valve and turn it clockwise to increase pressure or counterclockwise to decrease pressure. Be sure to consult the manufacturer's instructions for specific guidance on adjusting the valve.
The set pressure is the pressure at which a relief valve starts to open. When the valve is open and relieving, the pressure will be higher or lower than the set pressure, depending on the system and the valve design. That is the blow-off pressure.
A pressure regulator is a control valve that reduces the input pressure of a fluid to a desired value at its output.
To regulate the pressure to a pre-determined amount.
