how can i drain 180 degree water

Anthony Menafro

In N.J., you have to cool the water below 140 degrees F prior to draining. A holding tank, chilling tank or just running cold water while draining the high temp water are some options.

where can i drain my water distiller discharge water.... it's 180 degree water. do i need to make some kind of tank for it to drain into first before i allow it into the drain pipe?

This depends

..on your local codes and what your plumbing is made of.

Most plumbing codes require

that you cool the discharge down below 130 F (or other temperatures locally ordained) before discharging into a sewer. This is to prevent exploding flora and fauna and to keep pipe expansion at a minimum (cracking of cast iron, melting of PVC).

Normally such waste is held in a quench tank until cooled or is diluted with cold water (valve and thermo-bulb) for a more constant discharge.

Some enterprising souls use a plate heat exchanger and leverage that waste heat to pre-heat domestic hot water or help heat the place.

this unit is in the basement next to the bathroom. I dont think i can run it into the sink or shower because its so hot it will distroy the drain. do i need to get some type of tank to drain it into so it can cool down before it gets pumped into the drainlines? drains are pvc...

How much flow

Gallons per minute or gallons per hour? Is it in batches? You will need a tank and the flow rate will enable you to size it. Generally I would size the tank for an hours discharge plus 50 percent to allow space for dilution and just plain holding.

Depending on the rate of discharge you will need to use a good bit of cold water to dilute it. Are you making all of your domestic water this way? Do you have a use for heat such as domestic hot water or heating?

Is this a one time deal

David,

It kind of sounds like a 1 time deal from the way you are writing about it.

If so, I would make it really simple. I'd run a garden hose from the boiler to the shower, turn on the shower with some cold water running, then run out the boiler water so the mixed water temp is below 140. Don't touch the hose while it's draining!

If it's a more frequent thing, I would look at a tank, drain and the like.

I was thinking it was longer term

Jerry, given it was a water distiller (rent by the week?

But yours is a good question to ask, indeed.

I have seen counter top

distillers run into the kitchen sink drain. As I recall even a large residential point of use distiller doesn't discharge that much water. You should be able to get the discharge spec from the manufacture. Also suggestions from them on alternate drain methods.

Also many steamer units flush and discharge water in that temperature range, as well as commercial dishwashers.

Heck we are running condensing boilers into PVC pipe in that temperature range

Got snow melt???

I know where I'd be stickin' free BTU's...

Does the distiller run 24/7?

If so, you might consider pre-heating the incoming water with the water being dumped. GFX Technology makes some very nice drain HXs that might fit your bill. The low-tech, short term approach could be a barrel/bucket that the discharge runs into, and some Cu tubing that the incoming water runs through. Could kill two birds with one stone.

Ideally...

Ideally you could put in a small indirect and use it as a tempering tank to preheat the domestic supply coming into your water heater. Not a cheap solution though...
