floor drain for water heater drip pan


My inspector told me to install a floor drain for the water heater drip pan and water heater relief valve. This is right above the crawlspace.

does it need to have a P-trap? or is there something else
to use... how does that not dry out?

thx for input

No trap needed, But I would make sure it runs to an outside wall not just dump under the house.

Hi John,

The purpose of a trap is so that you do net get sewer gas into your home. The water trap prevents this. There is no sewer gas in your setup. It would dry out pretty fast anyway even if you had one to halt air or insect infiltration.

thx for input!

So it doesnt make sense to connect to the sewer because the trap would dry out, bugs, etc.

Just pull the line to the outside?

The soil underneath the house may be wet 24/7. The reason why you run the water heater tray drain out away from the house (and perhaps into a sewer) is that the floor drain connected to nothing but the ground below might not be able to absorb a larger flow from the tray fast enough and would then overflow onto the floor.

In my area we achieve this 2 ways- first is a floor drain connected to the sanitary system. It requires a ptrap. Since it is a seldom used trap it should also have a trap primer. These give a "squirt" of water to the trap periodically to keep it from drying out.
The other method is to pipe both lines directly to the exterior- if allowed.
I prefer the floor drain because it will also help you if you have to clean up a lot of water!
