EasyRid 480 Pressure Reducing Valve

Why use a pressure reducing valve in front of a filter?

Mains pressure fluctuates during the day and in some locations it can be higher than an under-sink filtration system can withstand. Pressure peaks strain housings, joints and filter cartridges. You can read more about how individual water treatment technologies work on our blog.

The EasyRid 480 static pressure reducing valve keeps a stable outlet pressure in front of the filter, even when mains pressure fluctuates.

Thanks to its small size it fits where a standard pressure reducing valve would be too large – typically in the cabinet under the sink. For H2O nanotec under-sink filters, fitting it is a condition of the warranty whenever the pressure is not already regulated at the house water inlet.

How does the EasyRid 480 work?

The EasyRid 480 works on the pressure compensation principle. Its simple and clever design ensures a precise outlet pressure even with large changes in inlet pressure.

Filter protection with the EasyRid 480 includes:

1. Pressure reduction – the valve reduces mains pressure to the outlet value.
2. Fluctuation compensation – the outlet pressure stays stable even when mains pressure changes.
3. Equipment protection – the filter behind the valve operates within a safe pressure range.

The outlet pressure is factory-set to 3–3.5 bar. The valve needs no electricity and no consumables.

What does the EasyRid 480 solve?

The pressure reducing valve protects the equipment behind it from problems caused by high or fluctuating pressure:

• pressure peaks from the water mains,
• strain on filter housings, joints and tubing,
• risk of leaks under the sink,
• unstable pressure at the filtration inlet.

Notice: The EasyRid 480 only reduces and stabilizes pressure. It does not filter water and will not increase pressure if mains pressure is low.

Who is the EasyRid 480 pressure reducing valve suitable for?

The EasyRid 480 is designed for applications with limited space and where continuous outlet pressure adjustment is not needed. It handles inlet pressure of 1–20 bar and water temperature of 5–80 °C.

The EasyRid 480 is especially appreciated by:

• owners of H2O nanotec under-sink filters,
• households with nanofiltration, ultrafiltration or reverse osmosis,
• installations in small under-sink cabinets,
• locations with high or fluctuating mains pressure.

To protect the entire home plumbing at the house inlet, a pressure regulator with pre-filter such as the IMT-M5 or IMT-M8 is more suitable.

Why the EasyRid 480 instead of a whole-house regulator?

A regulator at the house inlet protects the entire plumbing including the filter. If you do not have an inlet regulator, the EasyRid 480 is fitted directly on the filter supply and provides it with stable pressure – at low cost and without changes to the main plumbing.

If you already have a regulator at the house inlet, the EasyRid 480 is not needed for the under-sink filter.

Installing the EasyRid 480 valve

The valve is fitted on the filter supply hose, between the cold water supply and the inlet of the filtration system.

Installation steps:

1. Close the cold water supply (angle valve).
2. Fit the EasyRid 480 on the filter supply in the direction of water flow.
3. Slowly open the water supply and check the joints for leaks.

The outlet pressure of 3–3.5 bar is factory-set. Installation by our partner is available in the Czech Republic only; you can find tips for DIY installation on our website.

Will the valve affect water pressure or flow?

Yes, intentionally – the valve reduces the pressure at the filter inlet. The outlet pressure is factory-set to 3–3.5 bar, which is a suitable value for H2O nanotec filters.

The valve only reduces pressure. If mains pressure is lower than the valve's outlet value, the pressure remains unchanged.

How to care for the pressure reducing valve?

The EasyRid 480 has no replaceable cartridges. It is enough to check it during routine filter maintenance.

Consider checking the valve if:

• the water flow from the filter has changed significantly,
• a leak has appeared around the valve,
• you are replacing or relocating the filtration system.

A small valve that protects your filter

The EasyRid 480 keeps stable pressure in front of the filter even when mains pressure fluctuates, and it fits even into a small cabinet under the sink.

For H2O nanotec under-sink filters, fitting it is a condition of the warranty if the pressure is not regulated at the house water inlet.

Main advantages of the EasyRid 480 valve

• pressure compensation principle,
• precise outlet pressure,
• stability even with fluctuating inlet pressure,
• one of the smallest valves on the market,
• weight only 187 g,
• inlet pressure 1–20 bar, water 5–80 °C,
• 1/2" female thread on both ends,
• suitable for small spaces,
• no electricity,
• no replaceable cartridges,
• factory-set outlet pressure 3–3.5 bar.

⚠ NOTE: If water pressure is not regulated at the house inlet (e.g. by the IMT-M5 or IMT-M8 regulator), the supply hose to an H2O nanotec under-sink filter must be fitted with the EasyRid 480 pressure reducing valve. If this condition is not met, the filter warranty expires.
