Installation of the drain pipe for the temperature and pressure relief valve?

∙ 15y ago
It is the drain for the Temperature and Pressure relief valve (T&P valve, or TPV). It's function is to release pressure from the water heater if the pressure or temperature of the water exceeds preset limits. Do not cap off the pipe, or remove the T&P valve or alter it in any way. Doing so could cause serious injury or death! If you notice water dripping or running from the pipe, call a plumber to check it.

Can a hot water heater pressure relief valve drain into a sewer line?
Not directly.
Difference between Thermal relief valve and safety valve?
A thermal relief valve is a liquid-only relief due to expansion of a liquid with increased temperature.A safety valve relieves pressure due to a gas.It should be noted that "safety valve" is a general term which could refer to Pressure Relief Valves (PRVs) or Pressure Safety Valves (PSVs), terms which are used synonymously in some industries (such as the petroleum industry) to refer to all relief devices in general.
What is pressure valve?
There are various kinds of pressure valves. Perhaps the 2 most common in homes are the PRV (pressure regulating valve) which is on most incoming water pipes from a city supply. This valve limits the pressure entering the home system, bringing it down from city mains pressure. The second is on every hot water tank, and this is a relief valve, which will open up if the pressure in the tank becomes too high and vent the excess water down the drain.
What is head pressure on a drain line?
static head
When do you know when a backflow pressure valve goes in your boiler?
You see and hear water flowing out of it's drain tube into the floor drain.
Can a hot water heater pressure relief valve drain into a sewer line?
Not directly.
Can you hook up and rely on the Temperature Pressure Relief valve for a new electric hot water heater to a drain or do you really need an expansion tank?
Depends on your code. If you have a PRV or, as you would say, pressure reducing valve on your water supply to your house, you need an expansion tank. If your pressure is above 80 psi, you need a PRV AND an expansion tank.
Can you help me with this water heater leak please?
If the tank, shut the water off and drain with a hose on the drain faucet on the bottom of the tank. The pressure relief valve can be replaced (however a PRV is meant to drip, it has to expand.), so can vacuum breakers and the TP valve.
How do you drain coolant from a Mercury Cougar 97?
97 Mercury Cougar V8 (4.6L) instructions. Also for V6. Drain coolant as follows: a. If cooling system is still hot, carefully wrap a thick cloth around the pressure relief cap and rotate slowly until pressure begins to release. Step back until the pressure is released. b. Then rotate pressure relief cap until free. Remove the pressure relief cap . c. Raise and support vehicle. d. Remove splash shield from front of front sub-frame and body. e. Open radiator draincock and drain the coolant system. f. Lower vehicle. g. Remove the inlet and outlet heater water hose from the heater core. CAUTION: Do no exceed 10 P.S.I. of air pressure when draining the heater core or possible damage to heater core may occur.
How do you relieve the pressure on the fuel system on the ford expedition?
Relieving Fuel System Pressure *** A fuel pressure gauge, such as Ford Tool T80L-9974-B, is needed to correctly perform this procedure. *** 1. Disconnect the negative battery cable and remove the fuel filler cap. 2. Remove the cap from the pressure relief valve on the fuel supply manifold. Install pressure gauge T80L-9974-B or equivalent, to the pressure relief valve. 3. Direct the gauge drain hose into a suitable container and depress the pressure relief button. 4. Remove the gauge and replace the cap on the pressure relief valve. *** As an alternate method on models except 1997 F-150, F-250, Expedition and Navigator, disconnect the inertia switch and crank the engine for 15-20 seconds until the pressure is relieved. ***

How does a restriction orifice in a pipe work?
the orifice plate creates a restriction in the pipeline which creates a pressure drop across the plate. commonly found in high pressure relief systems or drain points (as this would usually be a HP/LP interface) and can also be used to measure flow, by measuring the pressure drop across the plate.
Will oil pressure switch drain oil?
The Oil Pressure switch if broken off will drain "pump" the oil out of the engine very quickly.

Dose a positive pressure drain need a trap?
A trap on a positive drain is used to avoid the 'contaminated' air in a HVAC system from traveling through the condensate line and entering into areas where it is unwanted. The trap becomes necessary when one condensate line is used for multiple units, especially if it is tied to other negative pressure drain traps. The negative pressure drain traps may not drain properly if they have to overcome the positive non- trapped pressure of another unit. It allows the condensate to drain more evenly, as well. Without a trap, the positive pressure from the unit can blow air through the drain with the water and cause 'spitting.' A trap on a positive pressure system may not always be necessary, but it is good practice to trap every drain and trap it properly. There are guidelines for both positive and negative pressure traps. Always follow the manufacturers recommendations.
