If you are not sure if you need a water heater pan, the short answer is YES. There are a couple of main arguments we advise our clients purchasing pans. Read more in the paragraphs below. As always, we are at your disposal at (858) 699-3185 if you have any specific questions not answered in this blog post.

Let’s Start with the ‘What’

What are water heater pans?

A water heater pan is a relatively simple device.  it’s a simple pan  mounted underneath your heater. must models  come with a drain hole for attaching a pipe for removing leaking water.

What happens is that the liquid runs down the pipe and goes into a drain placed nearby which prevents the room from damage.

Uncap the pan and fit with the correct pipe when installing it.

The majority of the models have PVC pipes, but this is not always the case.

Regardless the materials used most of them will usually do the job and they are pretty low cost devices to have.


Here are a couple of reasons why we think buying a water heater pan is a good investment:


It prevents from water heater damage

Of course water damage can cost you much more than the price you would pay for a pan.  Sometimes this may cause mold if you delay removing the leak appropriately.

Just be aware that this is not  an automated solution preventing you from water damage.


There are cases when a water heater May leak at the drain valve and the water pressure may cause the water leak to shoot pass the water pan. This is how even having a Pan won’t save you from the damage.

We could conclude that these devices are necessary, but they’re still great to have.



Pans work best if you really are able to provide a place to discharge the water. Otherwise you may just catch a very small amount of water and the rest may just end up on your floor.


How to choose the right type of pan of your water heater?

If you never had a pan before you may be actually shocked by the variety available in stores.  there are really a large number of pans. You can take a look at the basic types below and we believe this might help you determine which is the right one for your heating device.


Plastic water heater pans

The plastic models are usually produced with heart black plastic.  They might save you but there are better choices available.

What stick is just very vulnerable to various factors. A change in temperature could damage them; they could melt or break for different reasons. You may experience Leek but unaware of it for a long time I’m with a device like this.

Aluminum pans

The aluminum pans are the better alternative of the plastic models. One of the main advantages is that they are more reliable but still affordable. The pans are also highly resistant to corrosion.

Steel pans

The third kind of pans are the steel ones –  they are but highly durable and more expensive.

If you choose Steel better end up with a really good model that won’t rust. A rusty pan might be a recipe for a rusty heater in the near future, so be careful as it might cause you troubles.


Fiberglass water heater pans       

These are easy to maintain and have glossy finish. The fiberglass pans are really easy to clean too. You can find them in the same stores among the other models.

Now you already know what kinds of water heaters are available  on the market. will finish this work past helping you choose the right size.


Picking the correct size

Measure the diameter of your water heater –  this is the most correct way to discover what size will fit. Once done, think of the  space around the heater as well.

Choosing a pan made for just a bit bigger unit is something we recommend. An extra 2 inches can contribute a lot if you experience a leak.

Pan depth is the next feature to think of.  there are deeper pants but the idea is not to quote all the 40 gallons of water. If this happens it’s a sign you need a replacement.  You will be fine with a model that is less than 4 inches deep. What matters a lot is the nearby drain that needs to be connected with the pan.

Of course not everybody can afford having a pipe attached. In this case a deeper than can actually help a bit more. or just make sure you check the pan more regularly for possible leaks.
