Cause of Low Hot Water Pressure

When you are back from a tiring day or a heavy workout from the gym nothing will frustrate you more than a shower with low hot water pressure. When it comes to plumbing problems, it is difficult to diagnose the core problem with all those intricate setups.

Luckily we can help you with that!

Cause of Low Hot Water Pressure

When your shower is going at a snail’s pace and wants to take a day off, it is pretty troublesome diagnosing the root cause of the issue. There is so much that can go wrong with that and you can but left utterly confused as to what to do.

So we have compiled a list of possible problems and a troubleshooting guide for you to DIY your shower problems. So without further waiting let us get into it.

Low hot water pressure – The Top Causes

1. Blockade

Sometimes there is an easy answer to your question. Sometimes your plumber may identify that there was something stuck in the showerhead which makes you think that you could have done that yourself. Just open it, clean it out and you are good to go.

2. Leakage

Leaks are frustrating and this can be the most common underlying cause for low water pressure in your shower. The bad part is that the leak can be ‘somewhere!’ which means that you will call the plumber right away right?

Wrong! Before you can presuppose a leak, there is an easy way to diagnose leakages.

 To do this just turn off your taps and apply water pressure to see if the water meter still ticks. If it does, then you have identified a potential leak in your system and it is time to call a plumber.

3. Filters

If you are lucky enough to not find a leak in your house, then you can have a case of a water system that was deprived of its right to be maintained. These systems have delicate parts that need to be maintained now and then.

The filters in your water system are more susceptible to being blocked and luckily they are very easy to clean and replace.

4. Tempering Valve

Tempering valves are security measures implanted in your shower system so that you and especially your children can stay safe from boiling hot water.

But sometimes these valves can go bad and you might be having low pressure because either there is accumulated steam or the tempering valve has been blocked.

With a little bit of expertise, you can easily fix it or if needed replace it. I would, however, advise you to get professional assistance in this case.

5. Shower Head

Sometimes your showerhead is itself the problem. Believe it or not, some showerheads are specifically made to reduce water pressure. These showerheads are designed to reduce your bills. But they can also reduce your water pressure.

If you have just moved in, then there is a high chance that the same showerhead is still installed which can be restricting the water flow. Check first if your showerhead is the problem before moving further.

6. Clogged pipe

Another very common yet nasty problem is the pipe that leads to your shower. The pipes can sometimes be filled with rust, dust, and other debris like sediments and calcium deposits.

That will mostly depend on the area you live in and the type of water that the area has. If that is the case, then it is time to call the plumber.

7. Sedimentation

Sedimentation can occur if the water has high mineral deposits in it. When the water is at a high temperature these minerals get dissolved with water and run through it but after cooling, the residue can deposit inside the taps which if not taken care of in time, can cause restrictions in the water flow.

8. Bad plumbing

Plumbing is a skill that needs to be learned. You may think of yourself as a DIY plumber because you fixed some leaks in your sink. But there is so much more with plumbing; and if not done properly, there is so much that can go wrong.

One common plumbing mistake is to fit the pipes through a narrow unit which can restrict the water flow.

Troubleshooting Points

Here is a basic troubleshooting guide that you can follow to check your plumbing system to correct the problems yourself. But I still advise you to know this, that it is best to leave your plumbing issues to the professionals.

  • Check if all or just one of your water outlets has low hot water pressure. If it is just one, then you can troubleshoot yourself and look for the underlying common causes mentioned above. However, if it affects your whole house, then it is best to call for a plumber.
  • Are only specific taps affected by the problem? For example, do only hot water taps suffer from this problem? If so, then the most probable cause is your water heater. In this case, we recommend you not to mess with your system and call your plumber immediately as it can be downright dangerous.
  • There are high chances that your main shut off valve has been moved slightly which may be causing the low pressure. There is also a possibility that the pressure reducing valve is messed up and needs fixing or replacing. A professional plumber will know how and when to fix your PVR.

Conclusion:

Water pressure is often ignored until you are confronted with a serious problem. Sometimes the water pressure will drop if you are using multiple water taps at the same time.

That is not an issue and usually does not denote any kind of water problem. However, if your water pressure is consistently going down or has unexplainably dropped suddenly then this means that you have a water pressure problem.

If that is the case, then it is time to take some action. There can be an issue with just one of the parts of your house like your shower with low hot water pressure which can be fixed using easy troubleshooting, but a widespread water pressure problem indicates that you have a serious underlying plumbing problem.

In that case, I advise you to leave this to the professionals.
