Buying Portable Water Tanks For Pressure Washing
When buying a portable water tank for pressure washing, there are several key factors to consider to ensure that you make the best purchase for your needs:
Capacity
Consider the amount of water you will need for your pressure washing tasks and choose a tank with a suitable capacity.
Larger tanks may be more convenient for larger jobs, but they may also be heavier and more difficult to transport.
The capacity of portable water tanks for pressure washing can vary greatly, ranging from a few gallons to several hundred gallons.
The capacity you need will depend on the size of your pressure-washing projects.
If you perform small residential jobs, a tank with a capacity of around 35-50 gallons may be sufficient. If you perform larger commercial jobs, you may need a tank with a capacity of 200-500 gallons or more.
It’s important to consider not only the capacity of the tank but also its size and weight.
Larger tanks will have a higher capacity but will also be heavier and more difficult to transport.
On the other hand, smaller tanks may be more portable but will require more frequent refilling.
Consider your specific needs and choose a tank that offers the right balance of capacity, size, and weight for your pressure washing needs.
Material
Portable water tanks for pressure washing are typically made from one of the following materials:
Plastic
This is a lightweight and durable plastic material that is resistant to corrosion and impact damage.
It is a popular choice for portable water tanks due to its ease of transport and low cost.
Steel
Steel tanks are heavier than plastic tanks but offer a high level of durability.
They are often used in commercial and industrial applications where strength is a priority.
Aluminum
Aluminum is a lightweight and durable material that offers good resistance to corrosion.
It is a good choice for those who need a balance of durability and portability.
When choosing a material, consider the frequency of use and conditions in which the tank will be used.
Plastic tanks are a good choice for lighter-duty applications and are resistant to corrosion, while steel and aluminum tanks are more suitable for heavy-duty use and harsh weather conditions.
Consider your specific needs and choose a material that will provide the level of durability and portability you require.
Mobility
Mobility is an important consideration when choosing a portable water tank for pressure washing.
The tank should be easy to transport and maneuver to and from job sites, and it should be stable enough to prevent spills or tipping.
There are several features that can enhance the mobility of portable water tanks:
Wheels
Tanks with wheels can be easily moved and are ideal for use on job sites or in remote locations.
Look for tanks with sturdy wheels that can withstand rough terrain.
Handles
Convenient handles make it easier to lift and transport the tank, even when it is full of water.
Look for tanks with well-designed handles that provide a comfortable grip.
Compact Design
Choose a tank with a compact design that is easy to store when not in use.
This is especially important if you have limited storage space.
Tie-down slots
Consider a tank with molded-in tie-down slots to secure it during transport and prevent spills.
When choosing a portable water tank, look for a model that provides the right combination of mobility, stability, and convenience for your pressure washing needs.
Convenient Features
When choosing a portable water tank for pressure washing, there are several convenient features to look for that can make your job easier and more efficient:
Built-in Pump
A built-in pump can save time and effort by eliminating the need to manually transfer water to your pressure washer.
Look for a pump with sufficient power and flow rate for your needs.
Hose Connections
Convenient hose connections make it easy to fill the tank and connect to your pressure washer.
Look for tanks with well-designed connections that provide a tight, leak-free seal.
Level Gauge
A level gauge can help you monitor the water level in the tank and avoid running out of water during a job.
Choose a gauge that is easy to read and accurately displays the water level.
Secure Lid
A secure lid can prevent spills and keep debris out of the tank.
Look for a lid that is easy to remove and securely seals the tank when not in use.

Durability
Durability is an important consideration when choosing a portable water tank for pressure washing.
The tank should be able to withstand the demands of heavy use and harsh conditions without breaking down or leaking.
Here are several factors that can enhance the durability of portable water tanks:
Material
As mentioned earlier, tanks made from polyethylene, steel, or aluminum are durable and resistant to corrosion and impact damage.
Choose a material that will provide the level of durability you need for your specific use case.
Thickness
The thickness of the tank’s walls is a key factor in its durability.
Thicker walls provide greater resistance to impact and pressure and are less likely to develop leaks.
Seams
Look for tanks with strong seams that are welded, heat-sealed, or ultrasonically welded to prevent leaks.
UV-resistant
If you plan to use the tank in direct sunlight, look for a tank that is UV-resistant to prevent degradation of the material and maintain its strength and durability over time.
Reinforced corners
Reinforced corners can provide additional strength and prevent damage from rough handling.
By considering these factors, you can choose a portable water tank that is durable enough to meet the demands of your pressure washing needs.
