Enjoying a warm, rejuvenating shower is one of the great joys of caravanning. It’s also one of the essential comforts, particularly if you’re traveling in cooler climates. So if your caravan shower keeps going cold, it can be a huge inconvenience.
The main fixes for a caravan shower that keeps going cold include fixing the pressure valve, checking the water heater, fixing the plumbing, and adjusting the mixing valve. Other fixes might be as simple as descaling or replacing the shower head.
In this comprehensive guide, we’ll go in-depth on the different reasons why your caravan shower might be going cold and offer five easy fixes to help you enjoy a warm, relaxing shower.
Why Your Caravan Shower Keeps Going Cold
Nothing is more frustrating than getting into a cold shower, especially when you’re already feeling chilly. If your caravan shower keeps going cold, the water isn’t being heated properly. This is a common problem that can put a real damper on your caravanning experience.
There are a few reasons your caravan shower might not be heating up properly. And before fixing any of them, it’s crucial to understand the root cause. Once you know why your caravan shower is going cold, you can take the necessary steps to fix it. We will discuss some of these reasons here and offer easy fixes for each.
Caravans are fitted with showers that run on mains water pressure. The water boiler in your caravan heats the water, and then the pump circulates it through the shower head. When the shower goes cold, it’s usually because there’s insufficient water flow or the water isn’t being heated properly.
Common Factors That Can Affect Your Caravan Shower Heat
Several common factors can affect the heat of your caravan shower, some of which you can fix yourself, and others require a qualified technician. Here are some of the most common reasons for a cold caravan shower:
Low Water Pressure
Low water pressure is one of the most common reasons for a cold caravan shower. If the water pressure in your caravan is too low, it can restrict the water flow to the shower head and prevent the water from being heated properly.
Leaking pipes, a clogged showerhead, and a worn-out mixing valve are common causes of low water pressure. Low-flow showerheads can also cause low water pressure as they are too stingy with water.
Faulty Pressure Valve
If the pressure valve in your caravan is faulty, it can cause low water pressure and prevent the water from being heated properly. The pressure valve regulates the amount of water that flows into the caravan, so if it’s not working properly, it can restrict the water flow to the shower.
Broken Water Heater
Your caravan’s water heater is responsible for heating the water that flows through the shower head. If the water heater is broken, it will prevent the water from being appropriately heated and can cause the shower to go cold.
Leaking pipes, blocked pipes, and a faulty water pump can cause the shower to go cold. If your caravan’s plumbing system is not functioning correctly, it can prevent the water from being heated properly and cause the shower to go cold.
When there is a blockage in the pipes, it affects the water pressure and can prevent proper water heating leading to a cold shower.
Scale Build-Up in the Showerhead
Scale build-up is a common problem in caravans, especially if you live in an area with hard water. Over time, the mineral deposits from hard water can build up in the showerhead and restrict the water flow.
This can cause the water pressure to drop and prevent the water from being heated properly. It also prevents contact between the water and the heating element, making it harder to heat the water.
5 Easy Fixes for a Caravan Shower That Keeps Going Cold
After understanding the root cause for your caravan shower going cold, you can get it working properly again with a few easy fixes. We have listed five easy fixes for a cold caravan shower to get you started. Depending on the underlying problem, you may find your shower requires several of these fixes.
1. Check and Improve the Water Pressure
Low water pressure is one of the main culprits for a cold caravan shower. Before you do anything else, check the water pressure in your caravan. You can do this by turning on the tap in your kitchen sink and checking the flow of water.
If the flow is weak, then you probably have low water pressure. This affects the heating rate of your water and can make your shower go cold. There are several ways to improve the water pressure in your caravan.
Check all the taps in your caravan to see if they are leaking. A dripping faucet can waste a lot of water and reduce the pressure in your system. You should also check the aerators on all your taps and clean them if they are clogged.
Another way to improve the water pressure is to install a water pump. A water pump can help to increase the water pressure in your caravan and make your shower feel hotter.
2. Descale the Showerhead
Mineral deposits from hard water can build up in your showerhead, restricting the water flow and causing the shower to go cold. To fix this, you need to descale the showerhead. You can do this by unscrewing the showerhead and soaking it in a vinegar solution overnight.
In the morning, scrub the showerhead with a brush to remove any remaining deposits. Alternatively, you can replace the showerhead with a new one. This is a good option if the showerhead is very old or cracked.
3. Check the Mixing Valve
The mixing valve is responsible for mixing hot and cold water to get the right temperature. A faulty mixing valve causes temperature fluctuations and can make your shower go cold.
To fix this, you need to check the mixing valve and ensure it is set to the right temperature. You can do this by turning on the shower and adjusting the knob until the water is at the desired temperature. If the problem persists, you may need to replace the mixing valve.
4. Fix the Water Heater
If your caravan’s water heater is broken, it won’t heat the water properly and can make your shower go cold. To fix this, you need to repair or replace the water heater. You may need to replace the heating element if it is an electric water heater.
For a gas water heater, you may need to check the gas pressure. You should also check the thermostat to ensure it is set to the right temperature.
5. Check for Blockages
If your shower is cold, it may be because of a blockage in the pipes. This can happen if the pipes are old or there is sediment build-up. To fix this, you need to check the pipes and clear any blockages.
You can do this by running a pipe cleaner through the piping system. If the blockage is severe, you may need to call a plumber to clear the pipes. They have the tools and experience to do this quickly and efficiently.
