How long is the supplied tube and is there a max distance/elevation it can pump?

I would estimate that I need about 40 feet of tube and 5 feet of elevation for this to eject to a drain. Does this have the power to do so?
Asked by: brandeeno
no tube supplied at least in my purchase and I believe its 20 ft max elevation it can pump

Will this pump replace my older little giant white topped pump easily?

I mean will the input holes and mounting screws fit the same as the model VCMA 15ULST?

It should, it's one of the smallest size pumps out there and has three optional ports to connect to.

When in heat mode it created water but the internal tank was very small. We attached the pump and ran a small hose through the air exchange vent to the outside. This pump is extremely quiet, important in a living space. It is also very efficient removing the water.

Rated 4 out of 5 by from Excellent value pump with good features. I decided to buy this pump after I found the condensate from our A/C unit coming up from under the floor slab. I cut the drain pipe and directed it to a bucket for a while. An HVAC technician came out and looked at it. He recommended putting a condensate pump in which he would be happy to do for a few hundred dollars. I thought that was a great idea and knew I could do it myself. I looked around at various HVAC suppliers, but finally found this one on for a way better price. I found this pump to be a great value and I liked the features it came with, especially the high level switch. The pump is of all plastic construction, however it seems to be high quality. It pumps out all the water in just a couple of seconds, which I found surprising the first time I saw it run. It comes with a mounting bracket so you can mount it directly to the side of your air handling unit. Unfortunately, the pump didn't mount completely tight and it can move around a little while resting in the bracket. I don't think it will cause any problems though. You have to purchase some 3/8 I.D. tubing to run from the discharge fitting of the pump to a suitable drain. I went to the washing machine drain pipe. The feature I like the most is the HIgh Level Switch. It is a SPDT switch that can be used to shut down the air conditioning all together and/or sound an alarm. I wired it up to do both and it works awesome! I would recommend this pump to anyone.

Rated 5 out of 5 by from Works as advertised I ordered this pump partly based on reviews and it seemed like a good quality pump. The overflow switch can be wired into most modern furnace/AC control boards. This is a nice feature, especially if you are away from home with the AC on. Pump is quiet and has no issue pumping condensate vertically 6 feet and horizontally 20 feet into a deep sink (We has no nearby floor drains). Overall a great product at a great price.

Rated 5 out of 5 by from Piece of cake! Hard to say what I liked best about this product. In addition to the positives noted above, the manufacturer tech support was outstanding! They anticipated the homeowner installer, and were available every step of the way for me! I had to alter the product slightly in order to install in my crawl space using the drains as configured. I had to remove the safety switch, because I needed that drain port. I then placed a moisture sensor on the crawl space floor so that I would be alerted in the event of an overflow. They helped me figure out how to do all of this, and get the furnace up and running again. Really great support, they never once talked down to me because I wasn't a professional. Running real smooth for over a month now. No problems!

Rated 4 out of 5 by from Replaced old pump on furnace humidifier I cracked my old VCMA-15UL tank cleaning the basement. I ended up with this model as I couldn't locate another VCMA-15UL at the three local Home Depots in my area and needed a replacement right away. This pump does the job just as the less expensive old pump did. The rubber feet are a nice feature as this pump now sits on the floor instead of being attached to the furnace which reduces some of the noise from the old 'attached' pump. Pump noise is the same as the VCMA. A disadvantage for me is the smaller tank. When the humidifier on my furnace is active, this pump cycles on & off constantly due to the smaller tank capacity. This might not be an issue for AC condensate. I rewired the emergency shutoff switch from the furnace shutdown to the water solenoid. My drain is 7 feet up, then 15 feet across the basement ceiling.

Rated 5 out of 5 by from It was an easy install. On line research says it's a good product. My Home Depot service desk is great. I am disabled. I went to the desk, told the nice lady what I wanted. It wasn't in stock ( she sent someone to the shelf to make sure) She ordered it one line for me. Free shipping to my Door. It came via UPS. My wife installed it. Simple install. The weather is hot now and that pump is running like a son of gun ! Thank you all so much for helping me.
