How do I know if my thermal relief valve is bad?

Signs Your Pressure Valve is Bad

  1. Flooding: Water should never be gushing from the valve.
  2. Excessive noise: If your water heater is rattling or emitting a high-pitched whistling noise, it’s likely the sound of steam trying to escape the tank, which is a sign of far too much pressure pressing against the inner walls.

What is the thermal relief valve?

A thermal Relief Valve is a thermal protector for the pressure washer pump. It protects the pump from damaging heat that builds up while in recirculation/bypass mode. Opening temperature is 140°F. The valve will reset automatically once the pump relives the excess heat.

Where should a thermal relief valve be installed?

Install thermal relief valve as close to the pump casing as possible to avoid delay in response. Valves with male inlet threads may be screwed directly into the pump casing. Valves with female inlet threads should be close nippled to the pump casing.

When to use a thermal expansion relief valve?

Replace your expansion tank with the Thermal Expansion Relief Valve (TER-1). Features a pressure only safety relief valve designed specifically for the protection of hot water supply systems where over-pressure conditions are likely to occur as a result of thermal expansion.

What should the temperature of a relief valve be?

Rated for more than double the temperature of standard pressure-regulating valves, these can withstand temperatures up to 550° F. Withstand inlet pressures up to 3, 500 psi. Regulate pressure in air and inert gas systems from your instrument panel— these valves have threads below the adjustment knob and come with a panel-mount nut.

Why do you need a pressure relief valve?

Features a pressure only safety relief valve designed specifically for the protection of hot water supply systems where over-pressure conditions are likely to occur as a result of thermal expansion. The valve can be rotated after installation making it easier to reach the shut-off.

Is the Sharkbite 3 / 4 in.brass thermal expansion relief valve?

Hello, The SharkBite 3/4 in. Brass Thermal Expansion Relief Valve can replace an expansion tank. It is designed to open at 125psi. Most boiler applications operate at pressures below 30psi. This valve will not work in your closed loop heating application. If you have any more questions you can contact tech support at 877-700-4242.
