How well will this handle grit from soaps? Talking pumice and or walnut, looking at installing in...

Asked by Soupy January 29, 2021
1
Answer

I would probably opt for the Liberty 405, Home Depot SKU 304498827 because it will handle larger solids. Not because of the aggregate in the soap but because of the walnut shells. They could clog the intake screen on this one; the Drainosour. As to the soap, it does not pose a problem when the pump runs but when it is off. That is when it will coat the impeller. When the pump runs the impeller is not really touching the fluid. I know that sounds very counter intuitive but allow me to explain. When the impeller in a sump, effluent or sewage pump begins to spin it creates a negative pressure. The fluid boils because of this negative pressure. This is called cavitation. So the impeller is in an air pocket. Fluid is drawn to this negative pressure. This pushes the water in front of it ahead and that is how the pump works. The impeller is not acting like a water wheel as most people think it does. Instead it is creating the negative pressure and most of the fluid is bypassing it. I have taken many old pumps apart and you see no dings in the impeller because it has not come in contact with the solids. The solids are only in direct contact when the pump is off.

Can it pump over a 10’ interior wall?

Asked by Rob July 28, 2020

Answer

Pump performance is pretty much always expressed on a graph called a pump curve. On one axis is height and on the other axis is flow. The curve or graph illustrates pump performance at all these points. If you look under the header "Info and guides" on the Home Depot product listing page you will find a PDF of the specification sheet. if you open that document you will find the pump curve on the second page. If you look at 10' you will find that this pump will move 30 gallons per minute. What I can;t tell you is if that will meet your needs as I do not know what your needs are. Also I do not know if that is the total height you need. However i can tell you that as a best practice you want to select a pump where you application is at the center of the curve,. Meaning you don;t want to oversize or under size. That appears to be the case here.

Please open the Use and Care manual, a PDF of which can be found under the header “listing and guides” on the Home Depot product listing page. There you will see an illustration of the parts breakdown. I am sorry but I do not work for the Home Depot so I cannot tell you definitively what they would charge. However I can’t image it would be significant.

does the vent need to be piped to the outside

Asked by David November 13, 2019

Answers

Of course local code may require it but it is not necessary for the pump to function properly. I would recommend the use of an Oatey sure vent to help control sewer gasses

is the unit fully assembled? or, does the pump need to be installed into the container and then secure the lid to it?

Can Install this inside a sump pit?

Asked by mike September 16, 2018
2
Answers

This pump is designed to sit on a hard level surface and that could be in a sump pit. But this pump isn’t a sump pump and takes water into the pump through a plumbed threaded inlet in the top of the outer housing. It would not pick,water up from the bottom of the pit like a true sump pump would. If the sump pit never takes water and is dry all the time you could use the space in the pit for this pump. This pump is sized to directly fit under a typical utility sink and that is where I mounted mine. Hope that helps.

can you hook up multiple sinks and a washing machine to this pump

Asked by Bdmiller12 May 2, 2018
3
Answers

Yes. It depends on the discharge volume of water that the pump should handle. My washing machine discharge the water into the basin/sink and from the sink the hose connected to the pump that discharge the water into storm/sanitary system. It works fine and I had a great experience.

Please verify the gph specs for this pump. It seems it should pump more water with a .3 hp motor (drawing 9 amps). Thanks.

Asked by Mfa November 14, 2017

Answer

I am not completely sure what GPM figure you are questioning but I can say that the pump curve on the specification sheet, ( a PDF of which is on the Home Depot product listing page under "Info and Guides" ) is accurate. The curve indicates that this pump will have a flow rate of 45 GPM at 0-5", 20 GPM at 12.5' and will dead head, meaning flow rate will drop to zero at 16'. In my experience shape of the impeller as well as the volute will have a greater influence on the pump curve than the HP rating of the motor that drives it. For example many grinder pumps will have a curve showing much less of a curve than you would expect but they will rip a towel apart if it gets flushed. However most of the time they will not draw that much current. The current draw will drop off after the unit starts.

The pump looked well made as well as the outer casing, but the plastic holding structure, discharge pipe and gosh awful cheap filter cage was smashed to bits in the process of shipping to the home. I have discount kids toys that are better made. I thought about trying to fix it, but just returned it to the store. One would think that using heavy steel pump would signify a better all round product. Definitely was not Plug and Play...

This was a replacement item for me. The old one was at least 8 years old. The old one still pumped water but would not turn off on it's own so I had to remember when doing laundry to manually plug it in (so the utility tub wouldn't overflow) and then unplug it (so not to burn out the pump). The constant up and down the stairs was all good exercise and I have had some extra time at home these last few months thanks to Covid, but it sure is nice to have the luxury of a new pump with a working switch! Be sure to clean the screen regularly!
