Washing Machine Box

iamjeff · #1 Feb 27, 2006, 01:13 PM

Greetings.

My basement has an overhead Sewer pipe going out to the front. Therefore, if I want a washing machine in the Basement, I have to pump the discharge up and out in some way. Right now, the discharge goes to the sump pump hole and then is pupmed out. I want to install a washing machine basin (Supmpump box) from Home Depot and connect it directly to the overhead sewage pipe. What is the best way to connect to the 6" PVC pipe?

Thanks!

Jeff.

Hi Speedball.

It's a Flotec model from Home Depot:

* Maximum pumping capacities up to 2880 GPH.
* Heavy-duty 10 gallons polypropylene drainage tank.
* Model FP0S1800LTS - 1/4 HP.

I was wrong - it's a 4" PVC Sewage pipe. Do I simply cut a "Y"? Do I need a trap? Are there 4" to 1-1/2" PVC Reducers? Can you direct me to a diagram on how this should look?

Thanks for your help!

Jeff.

Hi Tom.

It has an inlet on the side, the discharge comes out from the top. It has a separate vent stack. Here is a diagram: http://www.flotecpump.com/pdf/PS80-29.pdf

They offer no connectivity suggestions. They stop their cutaway diagram at the height of the utility sink.

Any suggestions would be appreciated.

Thanks.

Jeff

Sorry to butt in, but is it possible to have the washer discharge directly into the 4" overhead drain pipe? I have the same problem as outlined, but my washer is supposed to drive discharge up to eight feet high. If it is possible to go directly into the overhead drain, how would I plumb for this so that there is no backup into the washer? Thanks.

Nice try , but no cigar! If you connected directly to the sewer line from your washer you would be opening up a direct OPEN CONNECTION from the sewer into your home. Every time you flushed a toilet or drained a bathtub the discharge would find itrs way into your washer. But that's just the begaining.
When the washer's setting empty there will be a open conection from the house sewer into your washer expelling sewer gas into your house.
It's possible to do this without a holdng tank and a pump but you would have to have enough room to trap, vent and run a washer stand pipe off the overhead sewer line. Even then you would have to install a check valve on the washers discharge hose to prevent the dirty water from draining back into the washer. Most overhead sewer lines don't have enough room to install a washer stand pipe. Rethink your project and If I can help click on back. Regards, tom

Tom, thanks for the reply. I can do everything, except the washer stand pipe. Therefore, a "dirty water" sump collection system will be the way to go. In that regard, does such sealed sump system need to be vented directly through the roof, or can it be tied into an existing vent system? I've read both recommendations. Tying into an existing vent system would be quite simple in my basement, but a new vent system would be much more difficult. Thanks.

There's one more option to consider. You can cut a Wye or combination wye and 1/8th. bend and install a vent before the trap. You may revent back into a dry vent if you wish. From the trap run a raiser up to within a few inches of the subfllor. Install a 2 X 1/12" compression fitting,(see image) on the raiser and connect the washer hose permanently to the compression fitting. There must also be a check valve installed on the washer hose where it exits the washer. A holding tank and pump are pricey so unless you specifically want one I'll hold off researching the different brands. Best, Tom
