Its primary function is to prevent water from reaching scalding temperatures while ensuring a comfortable and safe bathing or handwashing experience. Here's how a tempering valve typically works:

Inlet Water Supplies: The valve is connected to both the hot water supply and the cold water supply of a building's plumbing system. Hot water flows in from one inlet, and cold water flows in from another.

Flushing the drain with water is relatively straightforward to dislodge minor blockages. Begin by removing the drain cover or strainer. Use a garden hose connected to a water source or a high-pressure hose designed explicitly for drain cleaning. A power washer will help blast caked-on debris near the exterior and throughout the gutter system.

Schedule routine inspections to check for debris accumulation, such as leaves, twigs, or dirt, and promptly remove any obstructions. Installing drain guards or screens over the drain openings can act as barriers, allowing water to pass through while preventing larger debris from entering the drainage system. Additionally, it is essential to properly dispose of debris and maintain the surrounding areas to minimise the risk of blockages.

Mixing Process: Based on the temperature readings, the tempering valve adjusts the proportions of hot and cold water that are allowed to flow through it. If the incoming hot water is too hot, the valve will decrease the flow of hot water and increase the flow of cold water. Conversely, if the incoming hot water is too cold, it will allow more hot water to flow. The goal is to blend the two water sources to achieve the desired preset temperature.

Thermal Disinfection Valves: These specialized tempering valves are used in healthcare and institutional settings to facilitate thermal disinfection cycles. They can raise water temperatures to levels that kill bacteria and pathogens within the plumbing system.

Regularly sweep or remove leaves, branches, and other potential sources of blockages from the roof surface and the clogged gutter guards. In cases where the roof drainage system is complex or on a larger scale, professional maintenance services can provide thorough inspections, regular cleanings, and early identification of potential roof issues.

These drains typically contain several elements, including the drain bowl, strainer, downspout, and piping. The drain bowl collects rainwater from the roof and directs it towards the downspout, which carries the water away from the building.

Compact or Space-Saving Valves: In applications with limited space, compact tempering valves may be used. These valves are designed to fit into tight spaces while still providing temperature control.

Remove the drain cover or filter and position the vacuum hose over the drain opening. Turn on the vacuum and allow it to suck out the debris causing the blockage.
