- Reviewed in the United States on November 17, 2024Good quality and works, very satisfied.
- Reviewed in the United States on July 29, 2017ON MY THIRD SEASON OF USAGE
I have this TeraPump TRDRUM20 on my outdoor 55-gallon blue-drum (water barrel), and I am on my third season of usage. The water barrel is supplied by rooftop rain via a downspout diverter. I use this set-up to water my backyard urban garden of vegetables and herbs (pumping into a 1-gallon watering can).
The siphon tube is sized (34” length) to exactly fit a 55-gallon drum height (though can be easily trimmed to fit a shorter barrel).
The TeraPump’s cap fits cleanly and tightly into the standard 2” fine-thread bung opening, and still maintains a good seal after three years.
The siphon action is still strong … until my barrel is about one-quarter full (i.e. the height of my watering can) but I can still manually pump the barrel (sans siphon) until nearly empty (which is seldom necessary, unless we have a mini-drought period).
I cannot vouch for pumping anything but water, and that this TeraPump is made of HDPE #2 (food grade plastic) so it IS suitable for ‘drinking water’ (assuming, of course, the barrel contents are potable).
CAVEATS
This is not an indestructible device. It is entirely plastic and lightweight, and should be handled with care.
My barrel and TeraPump are located outside in complete shade, largely protected by an overhang. Thus, there has been minimal exposure to UV degradation … which IS an issue for (non-stabilized) HDPE.
I only use the pump for the six-month growing season (April thru September). I remove it, clean it, and store it inside for the other six months (freezing temps would most assuredly destroy it).
All that said, I estimate that I have pumped more than 2,700 gallons of water thru this TeraPump – one gallon at a time – now in my third growing season.
And I have just purchased a second one for back-up, because I figure I’ll need it … eventually.
- Reviewed in the United States on July 25, 2016Works as expected, though it doesn't do much when you get to the bottom of the barrel. If you stop it will just empty what is left in the stem back into the barrel. Not a design flaw, just not perfect. Hard to get into a pumping rhythm when it feels like I am about to pull the pump handle off the pump when I reach the top of the draw. For all I know, I could actually do that. I don't want to find out what might happen then. A mess I am guessing. Maybe just extend the top cap collar a couple inches so it doesn't hit the inside top of the pump when I reach or get near the top of the draw? idk.
- Reviewed in the United States on October 24, 2017We originally purchased the TRDRUM20 model from this vendor to pump water from our 55-gallon drum for different purposes. The pump arrived quickly and neatly packaged. The instructions are extremely easy to follow and installation takes seconds with the pump sealing well to the drum opening. Once flow begins it remains steady and at a good volume until the air vent cap on top of the pump is unscrewed (just a turn or two are necessary). We are currently recovering from severe hurricane damage here and since this pump has served us so well in the last couple of months, we have ordered a smaller model, the TRDP15, to use with some other containers as well as a second TRDRUM20 for the in-laws. The instructions also include a list of fluids which are recommended for use with each piece. I would recommend either of these models to anyone looking for an easy to use, light-weight siphon pump; Great products.
- Reviewed in the United States on August 1, 2024This is the best way I know of to get liquids out of a barrel but we also use it to transfer water to other places. We had the best results when the receiving container is on lower ground was on lower ground.
- Reviewed in the United States on November 9, 2013It does the job, but it leaves little plastic shavings from the pumping action in the water. I use this to transfer drinking water from 15 gallon jugs into a smaller jug that we keep in our kitchen. Hopefully after some use this unfortunate side-effect stops. Also, I can't get the siphon feature to work.
It does work for pumping so I think I can give it three stars despite the other negative aspects.
- Reviewed in the United States on August 13, 2019I wasn’t sure which siphon pump to purchase to use with my food grade 55 gallon water storage drums. A neighbor recommended this one. I bought it and tried it immediately. So easy to screw it into the drum and with only 3 hand squeezes and the bulb, the water began flowing. Towards the end of draining the drum I did have to pump more but it took barely any effort. I bought another for a friend to store in our earthquake sheds. Good product for a good price.
- Reviewed in the United States on May 22, 2018Every year we go do an event called “Flipside” north of Austin Texas and drinking water is always needed, especially in 100+ degree heat. We purchased 3 15gal water containers to take in case anyone might need extra drinking water. This perfectly fits the bung hole, no I’m not trying to be funny, (yes I am) and produces a good flow. Great product!
