Asked by Scion December 7, 20188
AnswersThe diameter of the pipe doesn't change the pressure back to the check valve. If you have a 1" pipe with a pressure gauge at the bottom and filled it with 27.5" of water the gauge would read 1 psi. If you took a 12" diameter pipe with the same setup and filled it with 27.5" of water the gauge would read 1 psi. Usually when working with water the manufacturer of pumps and what not would refer to water column or head. It's the height of the water that creates the pressure. It sound like this valve requires about 2.5 to 3 psi to seal correctly. You might be able to pipe it up near the basement ceiling (over the 6' mark) and put in a turn at the top to the drain? It may gurgle when in use but may work. Every 27.5" is 1 psi so if you have a 1000 gallon swimming pool that's 8.5' round and the water is 27.5 high at the bottom of the pool the water pressure is 1 psi, not the water supported by your deck...that's a different story.
CAN YOU USE 1 1/2" PVC ON THE DISCHARGE SIDE OF THE PUMP THRU TO THE DRAIN PIPE.
Asked by mike August 5, 20187
AnswersProbably with a fitting.
Why does my pump continue to cycle on and off without any water running?
Asked by Bushkanaka86 July 6, 20186
AnswersIt's because the backflow valve leaks. This allows water from the discharge pipe to drain back into the pump itself until it reaches the point where it trips the flow switch. Basically it's just bad design because there's really no such thing as an inexpensive leak proof backflow valve. The manufacturer's "solution" is that you're supposed to have 6ft minimum of discharge pipe length above the backflow valve to create enough pressure on it (via the weight of the water) to get it to seat tightly. Despite this meaning I had to run the discharge pipe all the way up to the underside of the floor above the backflow valve still leaks and the pump continues to cycle on and off so I ended up returning this and getting a laundry tray system (which is what I used to have)

Asked by Rickmo May 30, 20186
AnswersI would winterize using RV/marine antifreeze. That's the pink antifreeze. Turn the water off for the season, pour some of the antifreeze down the drain and let the pump run, unplug the pump while it's running so some antifreeze remains. That's it.
Has anyone ever threaded this directly to the drain stub without a transition pipe?

Answersits threaded and will accept a threaded/ female adapter to accept 1-1/2" pipe coming offf your sink. Works on the same concept as a garbage disposal.

I read a lot of reviews regarding the back flow valve leaking and the need to have a 6 foot vertical rise above the pump. I tossed the flap valve that came with the unit and got a spring loaded valve. No issues and no leak back with a 4 foot rise.the unit is a bit loud but it’s in a basement sink so I’ll live. Also I had to improvise on the plumbing a little. Putting it into a smaller cabinet.

Quiet, and efficient! Easy to install. The extra stuff that you have to buy isn't that pricey. Can't seem to regulate the flow that well but otherwise good product.

The AQUAPRO 1/3 HP UTILITY SINK PUMP is super for pushing waste water to the main household drain line. After installing it in a sub-basement (basement below lower level) bathroom sink, it pushed water very well. The unit is heavy and a little tall for vanity use, I will extend the sink drainline to free up under cabinet space. I will also get another one that will serve the lower wet bar lounge and kitchen area.

November 5, 2019
Installation was relatively easy IF you have some plumbing experience. Based on other reviews I purchased a higher quality check cable than is included with the pump (this valve essentially serves as the switch to tell the pump when to start/stop and is worth getting a good one). A few other exceptions to the install were going with all pvc vs the galvanized pipe recommended in the instructions (it would just rust eventually, no idea why they would call for it). I also added a rubber union so it would be easier to pull the pump for maintenance. Finally, I added a block of wood under the pump to support the pump instead of it simply hanging on the drain connection (it is very heavy).
Once installed it worked very well and can pump out an entire sink full in seconds - a very nice solution for those of us with a washer/sink below grade.

This pump is well-suited to draining a shop or laundry sink where the outfall pipe is above grade. It comes with key components for the discharge line (check valve and ball valve) and an owner's manual. See photo 1. The 1/3 HP rating suffices for small sink flows and it is wired for a 120 VAC convenience outlet. The pressure switch energizes the pump via a piggyback plug. Since my outlet is near a water fixture it is both switched and protected by a GFCI device. The pump has a 1-1/2 inch inlet which plumbs readily as this is a common small sink drain size. There is a strainer disc provided; but I found it more practical to use one or several selective strainers over the sink outlet. This is essential to keeping the pressure switch and check valve functioning! The impeller is a chemical resistant composite (See photo 2.) and the pump and motor are separable. See photo 3. The motor casing is vented on both its upper periphery and along its bottom. See photo 4. So I believe the motor is best cooled when neither of these is obstructed. The outlet side components are all 1-1/4 inch diameter. See photo 5. Advice is given for using the ball valve as a flow adjusting device - but I did not find that necessary. I don't use this for unattended purposes, such as laundry. so, under low flow conditions I might flip the wall switch and let rinse water accumulate in the sink... My outfall pipe was just below the ceiling, so I had no problem placing the check valve under sufficient head. I then made an inverted turn into a street ell on the outfall. All this is working well for me. The all PVC hook up with a union (and placing another local clean out in the outfall) was quick and easy. The owner's manual includes a Troubleshooting Guide.

Plumbing is simple, water comes in the top and its pumped out the side pipe to the sewer.
There are actually two (2) valves included, both of which go on the discharge line. One of which is a mechanical check valve and the other is a ball valve to control the discharge rate so that the pump operates as it needs to to maintain adequate water flow and control it to the point that is not flowing too heavily.
Once installed it was relatively quiet compared to the free standing sump type it replaced. Yet Its still a pump, its not silent by any means.
You will need to buy a few pieces of PVC pipe and a few pvc male adapters, none of which are very expensive.
October 25, 2019
This pump works great, no more bucket under the sink. Installation was easy, I use the plumbers tape for leak prevention on hand tight screw in piping. The utility sink we installed needed a drain, so we pump it into the washing machine drain (we swap out the hoses when using the sink). There is no need for a plumber or drywall work, just simple pipe connections, plug it in and away it goes.

October 23, 2019
This is a review of the Aquapro Utility Sink Pump. I got this to use on an outside sink I use in my garden. In the past I let the water from the sink drained on the ground but it made a mess where I stand, I put some flat stones there so my feed didn’t get wet. This pump is an excellent solution to that problem. Now with this pump and a length of flexible pipe I can direct the water where I want. I put the drain line under my ornamental plants and hedges so they can use the water. I moved the pump inside to my workshop for the winter. I set up a portable sink there so I can wash my hands in the shop and pump the water to a drain in the laundry room. The pump seems to be well made and durable. It has a 1.5” inlet that connects to the bottom of my sink. The outlet is 1.25”. The pump comes with a very good set of instructions that detail set-up and maintenance. I highly recommend this pump.
