TERA PUMP TRDRUM20 Emergency BPA-Free Drinking Water Drum Siphon Pump (5.5 GPM) for 55 Gallon Drums

ON MY THIRD SEASON OF USAGEI 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).CAVEATSThis 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.

Works 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.

Works well. About 100 pumps will fill a 5 gallon bucket in around a minute. Does not screw onto my blue 55 gallon drum because the holes are larger than the red piece, but still works fine.

We 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.

This worked well. This might be obvious to others, but if you are using it on smaller than 55-gallon drum, will need to trim it to fit. Moving parts are just accordioned plastic, so if this was a survival/must-have item, probably want a back-up. Don't know how long it would last under normal operation. What to do with the hose end between dispensing (drinking water in my case) is a bit of a quandary. Made a little "cap" for it out of a plastic bag.

Pump worked as expected, better than the one i had installed previously. Pumps water without issue and is easy to use. I recommend.

Its very useful and we would love to recommend to others who need a Pump for a barrel.

THE PRODUCT IS DEFECTIVE.
