Converting Outlet in Laundry Room to Accommodate RO pump

[Paul B]

By now I would have moved and found a house with a RO/DI outlet already installed and running in the laundry room.

That seems like a lot of work to power a 1/2 amp booster pump.

Sure but, you’ll have a set of useful outlets instead of a bump on the wall.

Thanks for the overwhelming response guys.
I’m going to just put the plug in unit behind the dryer. No alterations or potential violations going that route from what I’m reading.

Yup, that is definitely a code friendly option. Otherwise you can install a duplex receptacle to replace the simplex receptacle behind the dryer. Either one is a good option imo.

You can't plug a 20 amp plug into a 15 amp receptacle or adapter. It won't fit.
20 amp outlets have that silly "T" slot in them. Unless they changed the code again when I wasn't looking. ;Sour

I have a few of these because I keep removing them from my house. Screw the code.

Yup, but only if it is made in the US or actually built to US code. I've seen 120V power tools made in "a country which shall not be named" that pull more than 15A but don't use the proper 5-20P plug.

On the topic of code: is it code to have one of those adapters installed permanently?

The NEC is a construction standard so it doesn't address anything like this. OSHA could potentially have an issue with it but that doesn't apply to residential applications.

 

[KrisReef]

I do, one at each entrance so either can turn light on or off

You should be able to add a plug like the one shown in the picture fairly easily.

On a 20Amp 120 Volt Circuit with a Single Receptacle the NEC code states you must use a 20Amp Receptacle, not a 15Amp. For a Duplex NEC Didn’t Specify in 2020, however my County Code says you must use 20Amp Receptacles on all 20Amp 120 Circuits. Also on County Codes on all circuits, the Plug has to match the Breaker. Of course the Breaker must match or be below the wire Amp Rating.

Wow, this thread has really morphed into the qualification test for Electrician's Apprentice!

A question I meant to ask when I first jumped in. Does the RO/DI pump run continuously, on demand, or?? Does that affect the recommendations for the original question?

I almost never buy anything not made in the US (Which is why I walk around naked most of the time)

I'll open the box in a few and let you know. I just got the RO unit from Marine Depot a few minutes ago

I have a RO/DI unit with no pump, so I'm interested to know your setup.

 

[SteveMM62Reef]

You need a high pressure RO/DI Switch. They are made to plug inline from the Transformer, to the Pump. The water side goes in the RO/DI tubing after the DI and before the RO/DI discharge shut off. I set mine at 75 psig. I make batches of RO/DI water. i unplug my pump when it’s not in use. If you leave it plugged in all the time, and the water pressure drops, the pump will run dry and burn it up. They do make Low Pressure Shut off Switches, too.

 

[SteveMM62Reef]

Set up Available on Amazon.

 

[SteveMM62Reef]

Low Pressure switch, you’ll have to cut ONE low voltage wire from your transformer. Crimp Two Solderless Slip on fittings on the Stripped cut wire and plug into the two Flags on this switch. If you are on a well, or can loose water pressure and supply, this is a must, if you plan to leave the pump plugged in all the Time. Also this switch gets “Tee’ed In so you’ll need a RO/DI Tee fitting.

Why does @flyfisher2 need this?

You should be good with something like this....
