Hot Water, Low Pressure – What’s the Cause & How to Resolve It?

What you desire the most after a long, hard day or activity might be a nice, relaxing shower with a steady stream of hot water at the end. What if it’s a so-so bath in the weakest trickle of hot water that doesn’t suit your needs? We understand how aggravating and stressful low hot water pressure can be, and we also understand ‘why’ and ‘what to do about it?’ Low hot water pressure is a sure sign that something has gone wrong, whether it’s been brewing and worsening for a long time, or it’s suddenly ruined your shower or made filling up the kitchen sink into an endurance test.

The Reasons behind Low Hot Water Pressure

  • If the problem is persistent across the home, it may be a water supply issue rather than a leaky faucet. So has the water metre valve been shut prematurely by a vandal?
  • It’s conceivable that your hot water is feeding through a water filtering system. If you haven’t recently had yours checked, the filter may be restricting the flow.
  • In some homes, just turning on a second hot water outlet can cause the hot water pressure to plummet significantly – and it’s especially apparent in the shower. However, it’s frequently as easy as installing a quick-response hot water system with a capacity that wasn’t intended for numerous taps.
  • A faulty showerhead or tap is one of the most typical reasons for lack of or no hot water pressure. An ancient outlet’s insides will often build up limescale to the point that it obstructs it. Fortunately, a simple soak in vinegar may resolve the problem.
  • If you have a low hot water pressure problem in the house, ask if your neighbours have the same difficulties. If it’s a widespread issue, your next step should be to contact your water supply company, not the plumber.
  • The pressure was always maintained at a certain level, but if the pressure dropped below that level, it could cause additional problems. A pressure regulator might have been installed in some areas to bring the pressure down to an acceptable and safe level. However, if something goes wrong, the consequence might not be high water pressure but rather low hot water pressure.
  • Because your tap is typically blocked, it’s also possible that the supply line is clogged. There might be various reasons for the obstruction; however, your plumber is always the best choice to quickly identify and correct it – mainly because they may find that it’s a bigger problem than just a blockage.

Though low pressure is a widespread issue, everyone might have faced it once in a while, and instead of going with traditional solutions, there’s another long term solution which is getting a Hot Water Recirculating Pump installed in the water pipes between your hot water system and the rest of your house. Such a hot water recirculating pump has an automatic feature with either an internal or external flow sensor so that they will turn on as soon as you turn the hot water tap on, and the pump turns off when you turn the tap off.

Various High Pressure Water Pump Manufacturers make these, but the Water Pump Warehouse is a leading supplier of such hot water recirculating pumps and imports a range of high quality yet economical Hot Water Booster Pumps that are easy to install and can instantly improve your home hot water pressure.


Low water pressure can be a significant annoyance, but there are many ways to troubleshoot and fix the problem. Whether a faulty tap or a clogged pipe, your plumber is the best person to identify and correct the issue. In some cases, you may need to contact your water supplier company to get the issue rectified throughout your home. One of the premium solutions for this issue of low pressure is getting a hot water recirculating pump from a well-reputed high pressure water pump manufacturer.
