Your shower drains, the tap sputters. At Ultrices Leak Detection, we quickly track down the culprit regarding the cause of water pressure loss. Often, it involves a leak, a blockage, or a hidden pipe burst.
We check the cause of water pipe pressure loss at components such as the pressure regulator, check valve, aerator, water meter, main valve, central heating system, and boiler. Limescale, corrosion, a dirty filter, or a leaking water softener restrict the water pressure.
Couplings and gaskets, kinks in the pipe, frost damage, or ground subsidence also cause pressure drops. We help you quickly. Google reviews 5/5 Read experiences regarding the cause of water pipe pressure loss.

What causes water pipe pressure loss?
The cause of water pipe pressure loss concerns the reason why the water pressure in your tap, shower, or installation drops suddenly or gradually. It is the result of resistance in pipes, differences in height, material aging, or an actual water pipe leak. Basically, we distinguish between static pressure and dynamic pressure. Static pressure is the pressure without flow. Dynamic pressure is the pressure during flow. Pressure loss is caused by friction, obstructions, defective fittings, or a leak in the pipe. According to NEN 1006 and the VEWIN Waterworksheets, a drinking water installation must be designed and maintained in such a way that sufficient flow rate and pressure remain available. As a certified partner, we work with Kiwa-approved measuring instruments and report according to best practice protocols.
Signs and consequences of pressure loss in your water pipes
A low flow rate at multiple taps simultaneously, a slow-filling reservoir, or temperature fluctuations in the shower are typical indicators. Pressure drop can also be hidden and only become visible through a rising water meter reading or a wet spot on the floor, wall, or ceiling. With prolonged pressure loss, the risk of corrosion, limescale buildup, and even Legionella growth in dead pipes or rarely used taps increases, as described in ISSO guidelines. Companies notice this in pressure washers, steam generators, and commercial boilers stalling and displaying error codes due to insufficient supply pressure.
Main causes of water pipe pressure loss
- Blockage or calcification: The build-up of scale and corrosion in galvanized pipes, compression fittings, or aerators reduces the flow rate. Think of old risers or hard water areas of Vitens, Waternet, Dunea, PWN, WML, or Brabant Water.
- Defective or incorrectly adjusted pressure regulator: A sticking PRV pressure regulator or check valve causes a pressure drop behind the meter or directly after the main shut-off valve.
- Partially closed or stuck valve: A shut-off valve, balancing valve, or ball valve that does not open fully causes local or sectoral pressure loss.
- Filter or aerator cloggedPre-filters, dirt traps, and aerators can become clogged, visible as floating debris in the aerator of taps.
- Water pipe leak, visible or hidden: Cracks in PEX, PVC, or copper, leaking couplings, a leaking underfloor heating loop, or a kink in a pipe under the floor.
- Incorrect pipe diameter and long pipe runs: Pipes that are too thin or sections that are too long increase friction according to the principle of laminar and turbulent flow.
- Devices and fittings: Contaminated hot water boiler inlet combination, defective expansion vessel, backflow prevention with excessive resistance, or a clogged water meter strainer.
How does pressure loss work in the water pipes
Pressure loss follows the principles of fluid dynamics. In flow, pressure decreases due to friction along wall roughness and bends. Turbulent flow results in greater pressure loss than laminar flow. The effect becomes stronger with smaller diameters, higher velocity, and more fittings. Differences in height cause additional static pressure drop. In the event of a leak, water escapes, causing the system pressure to decrease permanently and the water meter to continue running. In extreme situations, cavitation can occur at throttle points or defective valves, resulting in audible vibrations and additional damage. The result for you is noticeable in a sluggish shower or a washing machine that takes longer to fill. A proper diagnosis requires measuring static pressure, dynamic pressure, and flow rate at multiple points while sections are shut off.
Our measurement method and process without demolition or breaking
We combine measurement technology, thermography, and tracer gas to quickly and accurately determine the cause of water pipe pressure loss. You receive a clear step-by-step plan with minimal inconvenience and maximum certainty, fully in line with NEN 3140 safety and VCA VOL procedures.
- AssessmentWe map out the installation from the main valve and water meter to taps, boilers, and any pressure boosting devices such as a hydrophore.
- Baseline measurementsWe measure static and dynamic pressure with calibrated manometers and data loggers and determine the flow rate per tap point.
- Isolating sectionsWe close off zones using valves to determine where the pressure loss or flow loss occurs.
- Leak detection techniquesWe use acoustic correlation, ultrasonic microphones, thermography, and tracer gas according to the forming gas protocol so that hidden leaks become visible without breaking.
- Analysis and reportWithin three days, you will receive an expert report including the cause, location, photos and video, repair advice, and indicative costs. Also available for insurers with coverage and no cure no pay on detection.

Quick checks you can do yourself
- Check the aerator: Unscrew the aerator and clean the filter. If the stream is normal afterwards, the blockage was local.
- Read the water meter: Close all taps. If the meter reading still fluctuates, there is a risk of leakage or a continuous float, for example in a concealed cistern.
- Test the pressure regulatorMeasure the pressure before and after the pressure regulator if possible. A large difference without flow indicates a defect.
- Open and close valves: Move the main valve and intermediate valves fully open and closed to dislodge stuck cones.

Frequently asked questions
What causes pressure loss in your water pipes and what is usually the cause?
The biggest culprits are leaks in concealed pipes, worn fittings such as compression or press fittings, a stuck pressure regulator, limescale in taps and aerators, a defective check valve, or a clogged filter at the water meter or boiler. Micro-leaks in hot water pipes or a leaking expansion vessel in the central heating system can also cause a silent pressure drop and lead to a rising water bill.
We often see pressure loss starting after renovations or when the water pressure regulator is older than five years. Using manometer tests, flow measurements, and acoustic correlation, we determine whether it is a hydraulic problem or an actual leak. If it is located in the bathroom, please also check out our explanation on thermography in wet rooms via thermographic bathroom inspection.
How do you recognize whether pressure loss is caused by a leak or by a defective pressure regulator or check valve?
A practical check is a night test with a pressure gauge at the water meter. Close all taps, note the pressure, and check after a few hours. If the pressure drops while nothing is running, there is a high chance of a leak. If the pressure remains the same but you still have a low flow at multiple taps, consider a clogged aerator, a defective pressure regulator, or a check valve that does not open fully.
We confirm this with pressure logging, section shut-off, and tracer gas for micro-leaks. Using thermography, we spot heat patterns around hot water pipes, and with ultrasound, we measure turbulence caused by constrictions. This allows us to separate component failure from actual leakage. If you want certainty in the bathroom without demolition, view our approach via bathroom leak detection without hacking.
How do you trace the cause of pressure loss without demolition work, and how quickly is there clarity?
We combine manometry, flow profiling, acoustic correlation, a thermographic camera, and hydrogen tracer gas. With this, we locate the leak to the centimeter, even in PEX, copper, or stainless steel pipes behind walls and floors. Our methodology is non-destructive and safe in accordance with VCA VOL and NEN 3140, utilizing certified specialists.
