CoronaTools LG 3710 RootIRRIGATOR, Red

Well built product, worth the price.

I bought my first Corona root waterer 3 years ago. I just bought a second one to help water the 80 plus trees I have to care for. They are sturdy and are a good value. They second one came with a shutoff valve. The first one, I had to add the shutoff valve. I also bought 2 fertilizer disolvers to root feed the trees.

There are a lot of low ratings for this product. People mistakenly believe the threads are not designed for US garden hoses. The problem with this product is it is poorly engineered. The inside diameter (the root diameter) of the female fitting on both the shutoff adapter and the waterer itself is smaller than the major diameter (the outside diameter) of the garden hose, so the hose cannot be fully screwed in. The fix is to grind down the thread on male fitting of the hose until it screws in easily. It will seat against the washer for a leak proof seal. There may be some garden hoses, generally cheaper quality, that have slightly smaller male fittings already, which would not have a problem. This is a somewhat irritating problem, but the fix is bench grinder, or a small grinding wheel that fits into a drill, and just go round and round the male nozzle until task is accomplished. The device, other than this, is pretty solid and should last a long time.

I was a bit cautious when I perfected this product after reading some of the negative reviews. I received the product and it appeared that I would have problems with the valve leaking. However a vise and a pair of pliers had the valve connections straightened out and water tight. Other than that this deep root waterer is perfect! It’s heavy duty, no leaks and made of good thick metal. I use it several times a week and is working well.

The construction was good but leaked miserably because the female connector was threaded incorrectly for typical US garden hoses.Ended up cutting the female connector off and replacing with a hose repair fitting but the company never replied or offered help

Effectively watered the deep root and revived small trees and bushes Water would just run off and not really get through the hard dry soil. Also saved water by getting water deep in soil where it needed to go.

I thought at worst I would get a little sprayed trying to use one of these. But, no, I had no problems at all. The hose fit up tightly without any need for adapter, tape, or other additional o ring. I bought 5 of these and stuck them in the ground pretty permanently and put a hose on each one and a splitter from the shut off and a timer and once a week I give my palms a good solid root watering and then on to the next week. Very easy to use. Actually used one to test how deep I could dig before hitting the rock. It is a better tool than I expected for the price and the shutoff and connector worked perfectly for me.

The media could not be loaded.  The handles are nice and thick, perfect for man hands. I found it to be sturdy enough to withhold severe pressure of me driving it into ground. * I like most the side drilled watering holes whereas the other irrigators have a single tip water hole which limits water dispersement. It is easy to use, the only issue I have is the brass water fitting is leaking, it does not shut off completely. Decent product, however; I am returning mine as it was defective.

I have used this product for a few months, and it works great. The product quality is excellent very well made and has great function. The molded grips make it easy to push the unit in the dirt. This is a great product with big value. Thx.

Works great and inserts easy into the clay gumbo soil around here. Using it to drown out ants, seems to be helping much! Haven't seen these in Canada other than Amazon - happy I bought it!

Hooked up to the hose easily and was able to deeply water my trees! Exactly as I wanted

Well made and easy to use root irrigator.

Just purchased this root feeder and immediately put it to use. It is well built and sturdy. It has a one-piece insertion rod, most offerings are two-piece with a screw joint in the middle, which I would consider a weakness when using in our very clay soil. The valve on the unit is very handy to control water flow. The three holes in the bottom distribute the water quite well. The cushioned handles are comfortable, but big. The depth indicator is a treat as it visually gives you a quick idea of how far you have inserted the feeder. All in all a very good unit. Would recommend.
