Lower pressure could be more severe than you imagine, potentially involving serious problems like leaking or cracked water pipes and may require professional intervention before snowballing into a home plumbing disaster.
The most common cause of low shower pressure is a blocked showerhead, as a result of limescale build-up. These blockages obstruct the water flow, leading to reduced pressure over time. Most showers are fitted with a filter, protecting the pipework from debris, but this can become partially blocked by scale.
One of the most common reasons for low water pressure is undersized supply piping. This is common in older houses where the original plumbing system is still in place. This will restrict the amount of water coming into your home and to the shower.
Homebuyers are often concerned about water pressure — and for good reason. Too much pressure could cause leaks1, and too little can make for an underwhelming shower experience.
If you have high pressure (achieved with or without a pump), you will get a better flow rate and can consider big rain heads, body jets and the ability to have two or more taps or showers on at the same time. A high pressure system will work well with a mixer, electric or digital shower.
If your water pressure seems low, the first step should be to test how much pressure you're actually getting from the shower head. A typical home's water pressure should be somewhere between 45 to 55 psi (pounds per square inch).
If your flow rate is less than 10 litres per minute, you may have what is considered low water pressure. Anywhere between 10 and 15 litres per minute is acceptable but can be improved. A flow above 15 litres per minute is considered good.
If you're looking for the most pressure, go for the 2.5 GPM Flow Rate, unless you are restricted because you reside in California, Colorado or New York. Again, this has been the Maximum Flow Rate since 1992. The step down from there in Flow Rate is 2.0 GPM.
Yes. High-pressure shower heads increase water pressure either by decreasing the flow rate or using a compression chamber.
A quick and easy way to increase water pressure is to adjust the pressure-reducing valve, which can be found in your home, usually close to your water meter.
Low boiler pressure can wreak all kinds of havoc on your heating system - it could leave you with no hot water and no heating. Luckily, it's a relatively easy fix that you can do yourself at home. Read on to find out more about what to do if your boiler pressure is too low, including how to fix it.
Depending on your current flow rate, you may be able to increase the flow simply by removing the filter or restricting device or replacing the showerhead with a higher-flow model, such as increasing to a standard 2.5 GPM head. Before you change the showerhead, make sure that the new model is legal in your area.
For water conservation purposes, most plumbing codes require faucets and showering devices to not exceed a certain maximum flow rate. Removing the flow restrictors could cause these devices to no longer meet these codes.
Depending on the details of your situation, a sudden drop in water pressure could indicate any of the following issues: Faulty plumbing fixture. Faulty hot water heater. Leaking/blocked water supply pipe.
Also known as "flow rate", GPM is a measure of how many gallons of water flow out of your shower head each minute. Since 1992, a maximum of 2.5 GPM is the federally mandated flow rate for new shower heads. This means no more than 2.5 gallons of water should flow out each minute.
A 2.5 gpm shower head will have a better pressure and shower experience than a 1.5 gpm shower head. A 1.8 gpm shower head would have a better pressure and shower experience than a 1.0 gpm shower head. Another drawback of low flow shower heads boosting the pressure is the temperature instability.
Many traditional showerheads offer an output of five or more gallons per minute, or gpm. With a low-flow showerhead system, the average is closer to 2.5 gpm, with some faucets offering amounts as low as 1.6, reducing the volume of water used in a single shower to a mere fraction of what was going down the drain before.
Low flow or water-saving shower heads are designed to reduce the amount of water wasted. Available with a shower heads with less than 2.5 gallons per minute flow rate. This is great for eco-friendly homes on water meters. Low flow means you have a reduced water pressure to reduce water waste and heating costs.
Efficient shower heads use at least 1.5gpm. Taking the same amount of time in the shower uses only 15 gallons of water. The water savings amount up to 65 gallons of water!
Residential water pressure tends to range between 45 and 80 psi (pounds per square inch). Anything below 40 psi is considered low and anything below 30 psi is considered too low; the minimum pressure required by most codes is 20 psi. Pressures above 80 psi are too high.
Normal water pressure is generally between 40 and 60 PSI. Most homeowners prefer something right in the middle around 50 PSI. Once you measure the water pressure in your house, you can adjust it to a setting that is ideal for all family members and household uses.
In general, residential water pressure ranges between 45-80 psi (pounds per square inch). If your water pressure is under 40 psi, it's considered low. A psi between 20-30 is considered very low, and under the minimum water pressure required by most building codes.
