Low water pressure in your outdoor faucet can be a problem when you come to wash the car, hose down the patio, or water your lawn. Insufficient water pressure can be caused by blockages or corrosion in pipework. Alternatively, there might be an issue with low water volume in your area or trouble with the pressure at which water is delivered. There are a number of ways you can diagnose the cause of low water pressure problems. It’s simply a question of troubleshooting a number of possibilities.
Remove all attachments fitted to your outdoor faucet. Hosepipes, sprinkler systems, and faucet adapters can significantly reduce the pressure at which water flows from a faucet. Try the faucet once all attachments have been removed. If the water pressure is restored, there’s not too big a problem to worry about.
Check your attachments for blockages or a build-up of limescale, especially if you live in a hard water area. Clean attachments with vinegar and fit them back into position before trying the faucet again.
If you have an irrigation system fitted, it may cause a loss of water pressure. This is common in irrigation systems that feature a built-in back-flow prevention system. Water pressure booster systems provide an ideal solution for this problem
Age of Your Property
Is your home an older one? If so the water pipes may be made of galvanized steel which has a tendency to become furred or clogged after many years of use. Under these circumstances, you may have to think about replacing the old steel pipes.
Water Supply Reception
Low water pressure in your outside faucet may also be a problem if you are the last to receive your supply from the water company or if you live uphill from the main water source. If this is the case, you might consider installing a booster pump to help rectify the problem.
It may be that you have recently had plumbing work done on your home. If so, it’s possible that pipe shavings, flux, or sediment have been transported into your system and are causing a blockage. Also, have a look at the aerator in the faucet as these can become clogged too. The first time you open the faucet after plumbing work, always look for signs of obvious leaks that can also reduce water pressure.
Your Water Supplier
In situations where there has been burst water mains or other problems in the neighborhood, the water supply to your household might be adversely affected. It’s always worth calling the municipal provider to inquire as to the current status of the water supply. They will be able to tell you if there have been any recent issues and they’ll also be able to let you know if you should expect any changes in water pressure in the near future.
Ask if there is anything you can do yourself to help increase the water pressure and, perhaps more importantly, ask if there is anything you should be avoiding if the problem is an ongoing one that the company is still dealing with.
