Question: What is the difference between the VCMA 20UL,   the  20ULS,  the  20ULT, and the 20ULST?
Document: I decided to get a more powerful one but did not know where to start.....  Skipping to the end I bought the VCMA-20ULST, where the ST just means that it comes with an optional safety switch (which I did not use) and 20' of tubing (which I could not use also because I had a much longer run than 20').
The 20UL is 1.5 amp and can push water 20 feet high under the same conditions.....I interpreted that comparison to mean the 20UL is more powerful......... so if the 15UL barely worked in my application the 20UL would work better. I was correct. Hopefully it lasts.Key1cc
I had the VCMA-15UL that came with the new construction home (3 years old) so I assumed it was adequate. The fault is mine as I never did any maintenance on my original condensate pump and after 3 years there was crud build up in the unit and in the long tubing run and the back pressure eventually caused the unit to overflow.
the pump works great and is very quiet. great deal for the money I use it for my dehumidifier and its been great
This was more than an adequate replacement for my previous furnace condensate pump. I am very satisfied with this pump.
Product design good enough and solve the task, which I need: move condensate water from dehumidifier to waist water pipe.
Of course it was a direct replacement so it took less than 5 minutes to swap with the old one.works great as does the original unit that's been functioning for &#62;12 years. I definitely recommend their products, especially with prompt delivery.
I've been using this pump for about a year now and this thing rocks. I used this to replace my 2nd replacement condensate pump for my high efficiency propane furnace and this one seems to be stronger, quieter, and better made than the one that was installed with my system.For the price? I think this would be really hard to beat.
I have used Little Giant pumps for many years. This time I upgraded from the 15UL to get some extra reservoir space an a tad more power. This little pump is a beauty and handles the condensate very efficiently. Just a tad on the noisy side when emptying but I guess that's normal for all pumps this size.
I bought 2 of these when my pump went. I installed one and kept the other in case of down the road. It was much cheaper than buying from the company who wanted 4 times the cost.
Answer: no
