Hallmark IndustriesMA0343X-4 Deep Well Submersible Pump, 1/2 hp, 110V, 60 Hz, 25 GPM, 150' Head, Stainless Steel, 4"

I bought this pump to replace the exact same pump that I bought 3 years ago. I had found a abandoned shallow well on my property that I wanted to pump from to water the yard. I did a horrible installation job the first time. I wired the pump by splicing an outdoor extension cord to it and plumbed it in with a 3/4" garden hose. The pump probably wasn't getting the proper voltage delivered to it and the small hose that had a permanent kink where it bent coming out of the top of the well casing must have caused constant back pressure in the system. On top of that, the entirety of my well is drilled through a layer of gypsum - causing the pump to operate in water that is saturated with sulfates. A corrosive environment to be sure.In spite of all of this, the pump worked very well. After three years in use, one of my underground wire splices (not the one at the pump) failed and I decided to just redo the whole system with proper wiring and plumbing. I pulled the pump out of the well and it was black with a corrosive stain. I tried testing it in a deep bucket and it pumped a little bit then quit. I'm not sure why it failed then, but considering the abuse that I put it through for 3 years and the harsh environment that it was operating in, I decided that this was a good opportunity to replace it - which I did.That the old pump didn't die on its own - I murdered it.The new pump is is now wired in with proper 14 Gauge wire and I've got 1" PVC pipe running from the top of the pump to ground level and then buried for a run of 40 feet to my water distribution point. When I turned the pump on, it worked just fine. The larger pipe is resulting in a much greater flow of water than I ever had before. Actually, it's a pretty impressive flow for a pump of this size.Bottom line: If you are looking for a well-built, robust, reliable and very reasonably-priced small pump, this is the one to get.

UPDATE 3/18/25: 3 years in, and the pump continues to perform PERFECTLY! Maintains prime and no drop in PSI or gpm volume.After a bunch of research and reading reviews, I chose the Hallmark Industries 1/2hp deep well pump for my irrigation system.My well is 44’ deep with a 24” diameter, so based on the reviews and research, this model (MA0343X-4-DO) was a good fit.Wiring the pump was pretty easy. Definitely need to use shrink tape, and I also used liquid electrical tape to seal the deal. And since I’ll be using the pump on an as-needed basis, I installed a 20A heavy duty inline rocker switch rather than a control box.The instructions recommend a check valve be installed (despite it having one built in), and rather than running into a problem later, it was a no-brainer to spend $12 on one from Lowes and install it about 18” above the pump outlet.They also recommended that you test the pump in a bucket of water prior to installation. Again, a no-brainer since you’d rather find a problem prior to dropping it in the well and completely plumbing it. Just put 3’ of water in a trash can, plug it in and make sure you get 6”+ of upright flow. With the check valve installed, the pump pushed water up about 12”. Not bad.Once installed in the well (pump suspended at 40’ with 1” ID black coil tubing) and plumbed with a variety of PVC connections, I tested it out and found the pump pushes 10 gpm @ 61 psi out a standard outdoor faucet at the top of the well, and 61 psi also at the end of a 75’, 3/4” garden hose. Not as much pressure (70-75 psi) as the Wayne PLS100 I use on a shallow well we have, but more than adequate for my sprinklers. And about $90 less than the Wayne.All in all, I ended up spending $195 in total for the pump and the various parts to plumb it up for my DIY lawn watering system. Bottom line is this pump is well worth the $130 price tag. ⭐️⭐️⭐️⭐️⭐️

Bought this to replace a failed septic pump going to two sprinkler heads. It was a much cheaper alternative. Since this is designed to go in a well I built an enclosure to put it in using thin 4" pvc from the garden center and two end caps. The bottom cap is permanently sealed. The top cap I put a small dap of pvc cement just to hold it in place for easy removal if needed. I used a 1 1/4 hole saw bit to drill the cap hole for the PVC exit pipe which fit tight to keep out debris. My previous outgoing pvc pipe had the right fitting already I just had to modify the length by cutting it down. I drilled holes in it and wrapped it with fine stainless steel mesh I bought off Amazon. The wire color was different than old pump. I bought the 2 wire + grd. Ground is green and the load wires can be reversed so easy to do. I used marine crimps and marine heat shrink to protect the wiring. Pump came right on and pumped my full efficient tank fast. You don't need an additional check valve for this application. I do suggest screening it like I did in case someone flushes something they shouldn't. With the drilled out tube and screen a baby wipe (not biodegradable) will get sucked to the outer casing screen which still allows for water to pump from several other holes and not clog the small pump screen. If it last it was worth it. It was longer than previous pump so I had to wait for the pump to arrive to get the enclosure cut to the right length. Hope this helps those who've experienced a failed efficient pump and needs a fast replacement.
