It is not unusual for plumbing issues to arise every once in a while when you use your shower and not affect the sink or every other pipe around the house.

The problem does not have to do with the entire piping system, so now the question is, what are the reasons why there is no water in the shower, but are the sinks perfectly fine?

If there is no water coming out from your shower, but the sinks are totally fine, the most likely issue has to be the shower head. It is either something blocking the flow of water from the shower head or a problem with the cartridge.

No Hot Water In Shower, But Sinks Are Fine

No Water in Shower, But Sinks Are Fine

Realizing there is no hot water in the shower, the sinks can be a very unpleasant experience. Not only is cold water not enjoyable, but it can also leave you feeling unhygienic.

If there were no supply of hot water all around your home, the primary culprit here would’ve been the water heater. 

But since it is just your shower, the most likely reason why this is happening is that:

#1. Your Anti-Scald Unit Is Too High

Let’s say you are getting hot water from every unit in your house, but your shower is only rushing with cold water; there’s a high chance that your anti-scald unit has been set too high.

What this limit does is that it limits how far you can turn your shower handle to set hot water and also protects you, so you don’t get burned by hot water. 

So, when your shower is not getting adequate hot water from your sink, the issue might be that your anti-scald unit is not properly adjusted.

You should contact a professional plumber that can help you fix this issue by; 

  • Take off the handle or head of the shower from your Fauset. 
  • Locating the anti-scald unit. 
  • Turn your anti-scald unit until he sets it in the correct position. 
  • Testing the water, and if it eventually gets hot again, your anti-scald was the issue. 

#2. A Damaged Mixing Valve 

A mixing valve helps you maintain the proper water temperature you need at any point in time by creating a balance between the mix of hot and cold water.

If your shower doesn’t have n anti-scald unit, then this is what you should be checking out for. A few problems that can affect your mixing valve, causing it not to work correctly, are; 

  • A broken valve. 
  • A worn-out valve. 
  • The plastic part of the valve is deteriorating. 
  • Improperly positioned valve. 

Most homeowners do the specific thing to conclude that the shower is the primary reason for all these, but your shower might be innocent in many cases.

The best way to check this is to check all other water sources like the sink, and if it only provides you with cold water, then the problem has to be from the water heater. 

For you to confirm if your heating system is the case and not the shower, you should check for some of these issues; 

  • Check if the thermometer in your water heater isn’t set high enough; this is one of the most common reasons why this happens. 
  • Check for technical issues with your water heater
  • Check if the fuse blows and if it’s a case with a gas unit, check the pilot light
  • If the heating system uses an oil burner, check if the oil burner ran out of oil. 

After fixing these potential causes and it still doesn’t supply water, you can be sure the issue is from the shower. Get a professional plumber to fix this because it can be complicated. 

No Cold Water in Shower but Sinks Are Fine 

Hot water not coming out of your shower is a clear sign of a faulty faucet, and if there is anything worse than a cold bath, it is a scalding hot one!

But, of course, you can never be sure if you do not find the exact problem, which is the first thing you should do. 

You should check if the problem is just within the shower in the kitchen or if it is all around the home, and if you realize that it is a general issue, it is most likely because someone switched off the valve. 

When turned back on, your shower should go back to normal. If it doesn’t go back to normal, then you should get your pressure-balancing valve checked because it is a problem. 

Other times, The two primary purposes of the pressure-balancing valve are regulating the hot water pressure and cold-water pressure and the ratio of cold and hot water flowing in the faucet. 

As time goes on, these minerals build up, and then corrosion starts to inhibit the cartridge’s effectiveness, which usually happens if you do not use the shower regularly. 

The solution to this is replacing the valve cartridge, and it is not all that difficult, even if it involves disassembling the faucet.

Many people would want to do this alone, but before trying this, you should know that removing the old cartridge is the most challenging part.

The steps involved in replacing an old shower carriage are listed below; 

  • Shut off the water supply from the shower. 
  • You should completely cover the drain underneath your shower to prevent small materials like screws and pins from falling in and disrupting your work. 
  • Remove the shower handle and every other metallic component you need to work on. 
  • Please take a quick snap of the disassembled parts as a reference when reassembling them back. doing this is an essential step for you if you cannot quickly identify the components.
  • Remove all the parts inside the Fauset, and then if there’s any dirt build-up, you can use a commercial cleaning solution to get rid of it. 
  • You can use a needle nose plier to remove the retainer clip and use a cartridge puller to pull out the cartridge. 
  • After installing back, the retainer clip and assembling every other part with the reference photo you’ve taken, you’re good to go.
