Camper van water expansion tank

Better Water Flow & Reduce pump cycling by adding a Thermal Expansion Tank in your camper van

When you’re on the road in your conversion van, having a reliable source of water is essential for your comfort and hygiene. But the water system in a conversion van can be prone to issues such as airlocks, uneven water pressure, and pump cycling. One way to address these problems is by installing a water expansion tank in your conversion van.

A water expansion tank works by providing a buffer between the water pump and the rest of the water system. When the water pump turns on, it creates pressure in the system, which can cause issues like airlocks and uneven water pressure. With an expansion tank, the excess pressure is absorbed by a diaphragm inside the tank, preventing airlocks and ensuring a more even flow of water throughout your system.

Here are some benefits of installing a water expansion tank in your conversion van:

1. Prevents Airlocks: Airlocks are a common problem in water systems, especially in smaller systems like those found in conversion vans. An expansion tank can help prevent airlocks by absorbing excess pressure and allowing air bubbles to escape.
2. Reduces Pump Cycling: When the water pump turns on and off frequently, it can cause wear and tear on the pump and reduce its lifespan. An expansion tank can reduce pump cycling by maintaining a steady pressure in the system, allowing the pump to run less frequently.
3. Improves Water Pressure: Uneven water pressure can be frustrating when you’re trying to take a shower or wash dishes. An expansion tank can help ensure a more even flow of water throughout your system, improving water pressure and making your van life more comfortable.
4. Protects Your Water Pump: Water pumps can be expensive to replace, so it’s important to take steps to protect them. By reducing pump cycling and absorbing excess pressure, an expansion tank can help extend the life of your water pump.

When choosing an expansion tank for your conversion van, it’s important to choose one that is the right size for your system and has the necessary fittings for easy installation. It’s also important to make sure the tank is made from materials that are compatible with the water in your system.

In summary, installing a water expansion tank in your conversion van can help prevent airlocks, reduce pump cycling, improve water pressure, and protect your water pump. By investing in this simple and effective solution, you can enjoy a more reliable and comfortable water system on your van life adventures.
