I am rehabing a house where they just let the washer drain onto the floor and into a floor drain in the basement. I don’t know where the floor drain goes, it might go to a sewer or storm drain in the Front of the house. But the house plumbing drains system is out the back of the house and the sewer connection is about 6ft above the floor.
This is a wedge shapped corner lot and there is a large drop from the level of the street in back and the one in front. Possilbe that there was even a septic system in the back when the house was built in the 40’s.
Anyway I am installing a basin pump. 10 gal closed resivor with effuent pump.
The unit had 1 1/2″ inlet and discharge pipes and is suppose to pump about 2000 pgh (33 pgm).
Most application drawings that I have seen show those type of devices looked up to utility sink parralled to the standpipe when used with a washer, but direct connected for DW or bar sink applications.
NOWEVER, I have not seen any instructions that even suggest that the utility sink is needed. The drawings are just “typical” uses.
My question does anyone have any experience with this and will the basin pump keep up with the washer or do I need the utility sink for overflow.
I have no problem with using the utility sink, execpt that this is a tight area and will need to do some other work if I have to install one.

I dont think a basin pump will keep up with a normal washer . If I remember right a washer discharges 30 gallons per tub full. A 10 gallon tank would be nothing for that . A basin pump will ddo the job if the tank size will hold a full load of water at once.
My laundry sink actually stops draining while the pump catches up . A washer wont wait on spin cycle discharge.

I suspected that the holding volumne of the basin pump was not enough.But there is another part to the equation.The speed at which the pump can discharge.I have no idea if that enough to keep up with the discharge rate of the washer or not."My laundry sink actually stops draining while the pump catches up . "Then you have a similar arangement. But the washer does not backup in to the sink? You have any idea what the discharge rate for your basin pump is?
My washer is not hooked to the basin pump as its up stairs . I dont know the rate of the pump but thats not the problem. It nearly fils up before it comes on so it doesnt run al the time .

I've got a sump pump in a 55 gal plastic barrel under my back deck that handles the washer and the shower in one bath. The float switch kicks in when the water gets just over the top of the pump, and elevates the float. It sucks faster than the washer can discharge on a full load. It's a 1-1/2" discharge Sears.
Off yer azz and on yer feet,
Outta th' shade and into the heat.
My washing machine dumps into a sealed sanitary sump pit in the basement floor. I assume that's what you're talking about?
The pump runs about 5 seconds on and 10 seconds off when the washer is draining. So it has plenty of capacity.
For years I had a sump or basin pump under a double laundry tub. For the first few years, it worked great but like most pumps, gaskets and switches go bad. The double laundry tubs can handle a full heavy load of water from a washing machine which saved me from a flooded basement.
My pump - don't remeber the brand - did not keep up with the washer - it was close but still could not do it - it was pumping up 6' to my waste line to the septic system.
Having the luxury of being on a farm, I finally dug a dry well where my basement opens to ground level. It drains very quickly now but still have some water in the laundry tubs for a couple of minutes after the rinse cycle.
Moral - double laundry tubs and a basin pump will work, but go with both.
