Common Low Water Pressure Problems

Have you ever noticed a sudden, unexplained drop in your home’s water pressure: especially of late in Kalamunda or Mundaring home?

As one example, perhaps it’s taking a little longer than usual to full the tub or the kitchen sink. You might have shrugged it off, planning to get it looked at some point. But that’s not a very good idea as low water pressure can be a symptom of a bigger and more complex problem.

In fact, whether you’re experiencing reduced water pressure throughout your entire home, or from a particular tap, it’s worth having the issue explored by a local plumbing professional.

There are also ways to conduct a little private investigation of your own, including the following:


If the water flows slower than usual from your kitchen or bath tap, but other fixtures are performing well, you might have a clogged aerator. Over time, sand, rust, scale and other deposits can build up and restrict water flow. Simply remove the aerator and clean it with a commercial descaling agent.

Supply valves

If the aerator is clean, check the supply valve under your sink to make sure it’s in the open position. Even a slightly closed supply valve can greatly reduce water flow.


Another fairly common cause of low water flow are leaks. Some might be obvious, like that pesky drip from your bathroom tap. Others might not be easily detected, like one resulting from a hairpin-sized hole in your water pipe. Either way, leaks need immediate attention as they not only waste water, but could result in structural damage to your home.

Water filter

If you have a whole-house water softener installed and are experiencing low water pressure from every tap, you might need to have your water filter serviced.  In the meantime, try putting your filter in the “bypass” mode.  If the water pressure returns to normal, then the problem is with the water filter unit.

Main water supply valve

Similar to a localized supply valve, if you home’s main water supply valve is not wide open, water will not flow through the pipes at the rate it should. While you’re there, check for any corrosion as that also could be restricting the flow.

If your home detective work comes up empty, or you think you’ve located the source of the problem but need professional assistance to make matters right again, contact Kalamunda Plumbing for prompt, professional, and reliable service.  After all, we know plumbing, inside and out.

Customers Say

Great Service and very professional.
Dean Jones
I have given Kalamunda plumbing 5 stars but only because I couldn’t give them 6!Kalamunda Plumbing we’re absolutely fantastic! I had a burst pipe somewhere on my property (3000 sqm) leaking at 1L per second. I tried 4 different plumbing companies before coming across Kalamunda plumbing. The first company made me wait two days and then forgot my booking, the next one couldn’t help me for over a week and the last quoted me $1200 for the job and still had to wait three days. I called Kalamunda plumbing and they arrived the very next day. Anthony found the burst pipe within 20 minutes to the exact location, dug down and repaired the leak. The whole job only took 2 hours and was 1/3 of the price I was quoted.They were professional, helpful and friendly. I will now be a customer for life. I have shared my experience with all that I know in my area.I cannot recommend them highly enough. Thank you for everything! When the need arises I will be back!

We had a large amount of water bubbling up between the pavers down the side of our house. After a quick call around and a few dead ends I got hold of Kalamunda plumbing. They were able to have someone around quickly, dig down and repair the broken water line. Saving me a fortune in wasted water. Highly recommend and definitely will be using for any future plumbing work.
Trent and Barry from Kalamunda Plumbing did an excellent job. As well as fixing the problem in a timely manner, they gave me some good advice on a number of other potential plumbing issues
Roger Barnett
One thing that I really appreciate is a tradesman that arrives when they say they will, especially when you have taken time off work to have your hot water system replaced.Kalamunda Plumbing were on time and I can't believe how quickly the work was done, and at a reasonable price considering that they did an urgent repair for me. Everything was back to normal again so quickly, mess cleaned up and they adjusted the water temperature so that it was not hot enough to scold me.Well done to everyone involved at Kalamunda Plumbing, greatly appreciated.Regards Russell
