What’s the Deal with Water Pressure?

When it comes to taking a nice, relaxing shower or trying to wash dishes for the seventh time that day, there are few things more frustrating than issues with water pressure. But what causes those issues in the first place? While there are a number of potential causes for both high and low pressure, we’ll go over some of the most common. 

Causes of High Water Pressure

The recommended range for water pressure is between 55-70 psi and anything above 70 psi will result in high pressure. 

There are many possible causes of high water pressure. Some of the most common include a broken pressure reducing valve, seasonal temperature changes, fluctuations from the municipal water supply, and high municipal water pressure. If you live in an area where new homes are being constructed, oftentimes pressure is increased in order for the water to travel effectively to the new homes. An unwelcome result of that increase can be high pressure in your home as well. 

While it may be tempting to ignore, the long-term effects of high water pressure are costly since it affects the longevity of appliances and fixtures and puts stress on your plumbing system, increasing the risk of pipe bursts and leaks. 

To combat high pressure, Premier Plumbing can install a pressure reducing valve (PRV). Depending on the accessibility of your pipes, installing or replacing a PRV typically costs between $500-$800. When you take into account the cost of replacing appliances and other fixtures throughout your home, as well as damage caused by burst pipes (which might require you filing an insurance claim and paying your deductible), installing a PRV is well worth it. 

Why is Pressure too Low?

The causes of low water pressure are more challenging to pinpoint. One common cause of low pressure is geography. In some instances, low pressure is a result of the amount of water the city provides your home with. Your proximity to mountains can also play a role. In those cases, there isn’t much you can do to remedy the situation besides installing a water pressure booster pump. 

If your home is older, the pipes themselves could be the issue. Older homes often utilize smaller pipes which naturally limit the amount of water that can travel through them. Galvanized water lines can appear fine from the outside but might have rust inside the pipes which shrinks the diameter, limiting the flow of water. In instances where there’s a pressure-reducing valve (PRV), the valve can become clogged or fail, contributing to your pressure issue. If you’re experiencing low water pressure at a single fixture, the aerator may be clogged with debris. Another option is a supply line might be clogged. 

When water pressure is normally fine but suddenly drops, check city municipal communications. A city-wide issue like a water main break could be the culprit.
