Water pressure is the term used to define the flow of water through a pipe, with the force of flow measured in pounds per square inch or PSI.  The speed at which water flows from the opened outlet depends on the amount of "push" or pressure that exists at that time in the system:


  • The higher the pressure, the stronger the “push” behind the water
  • The lower the pressure the weaker the “push” behind the water


Water companies, both civic and private, use pumps and pumping stations that increase water pressure in the main lines to about 200 PSI.  200 PSI, is satisfactory for firefighting, high-rise buildings, and to compensate for elevation increases, but is excessive for residential use.


GPS Plumbing provides a complete set of residential water pressure normalization and optimization service for both high and low water pressure problems.


High Water Pressure


If the water pressure is too high, the key solutions to normalizing (reducing the PSI) the water pressure include:


  • Installation of a Pressure Relief Valve (PRV)
  • Repair and or replacement of a faulty PRV
  • Resetting the pressure level of an operative PRV, or
  • Other solution that reduce the home’s water pressure to an acceptable PSI


About Pressure Relief Valves


The Pressure Relief Valve is an important plumbing element that:


  • Controls the difference between the water pressure needed within a home and the supply pressure
  • Protects a home’s appliances and plumbing fixtures from damage when water pressure is too high
  • Saves water and energy by reducing the amount of water used at various fixtures and appliances
  • Saves costly piping repairs and eliminates those annoying banging sounds (water hammering)


Low Water Pressure


When the pressure is too low:


  • We know the causes, cures, and solutions and will fix the problem quickly and efficiently


Our experience indicates that water pressure problems are usually ignored, misunderstood, and go unresolved for months and are the root causes for many avoidable plumbing repairs.


Normal Residential Water Pressure


The range of normal and optimal water pressure for a residence is:


  • Normal - 30 PSI to 80 PSI
  • Optimal - 45 PSI and 60 PSI


Water Pressure Problems


Water pressure related problems include:


  • Low water pressure
  • High water pressure


with each having a unique set of solutions that bring the water pressure within normal ranges.


Low Water Pressure Problems


When one or more fixtures in a home fail to deliver an adequate flow of water (low flow), the condition is referred to as a low water pressure problem.  Following are some of the most common culprits for this plumbing condition:


  • Under-sized, rusting, corroded, or outdate galvanized piping
  • Partially closed or defective main shut off valve
  • Faulty pressure reducing valve
  • Improper pressure reducing valve setting
  • Clogged faucet aerator
  • Partially closed or defective water heater shut off valve
  • Narrowing of galvanized iron pipes caused by buildup of minerals
  • Leaking, burst, or defective pipes, valves and or fittings
  • Water softener problems
  • Location of house relative to water tower – uphill location with pressure hindered by gravity
  • Other causes


If you are experiencing any of these low water pressure problems, call GPS Plumbing at 469-777-0217.  We will find the source of the problem and provide a solution.


High Water Pressure Problems


When a dwelling’s water pressure exceeds 80 PSI, a high water pressure condition exists.  The effects of long-term excess water pressure can be disastrous for water lines, plumbing type appliances and fixtures, and home plumbing in general.  Finding and fixing high water pressure problems early, saves money and inconvenience in the future.


High water pressure problems have distinct indicators, but every home differs in age, plumbing design, elevation, style (one or multiple stories), and pipe material.  These factors can affect the high water pressure indictors – they may or may not be obvious.  Common and obvious high water pressure indicators include:


  • Slab leaks
  • Burst piping
  • Water hammering, banging, or noisy water pipes when turning on or off water at a faucet or tap
  • Spitting from the water faucet aerator when water is turned on
  • Leaking faucets
  • Running toilets
  • Septic drain field flooding when home connected to a private septic system
  • Water heater tank explosions


Other less obvious indicators include:


  • Increased sewer related fees when sewer charges are linked to water consumption (more water usage = sewer related costs)
  • Increased hot water heating costs (higher pressure = more cold water flowing = more hot water heating costs)
  • Shortened water heater useful life
  • Shortened washing machine or dishwasher useful life
  • Wasted water - running water at higher than needed pressure and flow rate = wasted water, and
  • Other less obvious indicators


Our experience indicates that a significant number of home plumbing problems are directly linked to excessive water pressure, and include some of the most costly to repair including:


  • Slab leaks
  • Water heater replacements
  • Repair/replacement of burst or leaking water supply piping
