Questions and Answers for Little Giant WRSC-6 Compact Drainosaur 0.3 HP Water Removal Pump System

A:  I am sorry I am not sure I understand your question. This product is intended for outdoor installation. It is typically installed indoors under a laundry sink to pump gray water up to an elevated drain line. If you scroll down the Home Depot product listing page you will come to a section entitled Product Details. If you expand that section, you will find PDFs of the product documents. The Instructions contain an illustration of the common installation.

A:  The pump has a float that activates the water discharge. Connecting the washing machine directly to the pump may back up due to the delay of the float.

A:  Plumbing codes vary state to state and their interpretation vary inspector to inspector. Therefore I cannot give you definitive answer. For that you would need to speak to a local qualified licensed plumber or the plumbing inspector in your town. But I can give you a little info. Sewer gas contains potentially lethal odorless gasses. Tying into a sewer system must be done correctly. Only “plumbing fixtures” tie into the plumbing system directly. And they must be vented to allow the sewer gas to pass back into the main stack. For this reason you would never tie a washing machine directly into the sewer system. It is not a plumbing fixture and is not constructed to deal with the vapors and be directly connected. To get around this washing machines will sometimes dump into a pluming fixture such as a laundry sink. This is called and indirect waste. Now you don’t always need a sink to create and indirect waste. This pump system can be plumbed into the drainage system. The discharge and vent get tied in according to code. The pipe bringing waste water to the pump would needs to have a p-trap between the washing machine and the pump to prevent sewer gas from entering the living space. On that p-trap plumbers will sometimes attach a stand pipe rising to a height above the top of the washing machine. They then put the discharge pipe from the washing machine into this pipe. The washing machine will then pump the water up and into this pipe. The waste water will drain into the p-trap and then into the pump. But again you would never put the washing machine discharge pipe directly into either this pump or into the main sewer line. Sorry if that is confusing but I is difficult to describe.

A:  First let us define "soap scum" and have a common definition. The name would lead you to believe it is residue from a house hold cleaner and therefore a different cleaner may be a solution. However what is describe as soap scum is typically not soap based. Instead It is frequently a mineral residue and build up, although certain cleaners can exacerbate this. Now the best way to prevent mineral build up is to remove these impurities from the water. There are many different minerals and mineral combinations found in potable water. The best practice is to have the water tested. Once the contaminates and there concentrations have been quantified a filtration prodigal specific to those minerals can be selected. There is no reason to install a filter for minerals that are not present. Some contaminants are larger than a water molecule and simple to remove. Others are smaller than the water molecule and require a more elaborate process. This is often the case with hard water. Inside water softeners a chemical process to remove the ironized minerals takes place. The media bed, where this takes place is periodically regenerated using salt. Your situation may not be that bad and may not necessitate such an investment.

A:  wish it wasn't soo loud. i can hear it while I'm upstairs.

A:  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.

A:  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.

A:  We can try. If you look in the spec sheet you will see that the part number is 113132. If you would like to call us with your Home Depot order number we can pull you up in our system and have Little Giant send you one. Unfortunately with out that they will require payment for the part and shipping. If you don;t have that available but did buy it from the Home Depot you can call them and they can pull it up for you in there system and give it to you. Thanks Chris

A:  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.

A:  The part number of what you are looking for is a 108082. If you give us a call with your Home Depot order number, I will be able to bring your order up in the system and have one sent to you. Chris 978 651 3301
