A submersible well pump is a sealed motor and pump assembly that sits deep inside your well, completely submerged in water. Unlike jet pumps that sit above ground and pull water up with suction, submersible pumps push water up from the bottom — making them far more efficient for the deep wells common across North Texas.

Most wells in Parker, Wise, Hood, and western Tarrant counties tap the Trinity Aquifer at depths between 150 and 600 feet. At those depths, a submersible pump is not just the best option — it is the only practical option. Jet pumps cannot lift water from more than about 70 feet, which rules them out for the majority of wells in our service area.

Legacy Water Well specializes in submersible pump systems. We install, repair, and replace submersible pumps every day across North Texas, and we carry the most common sizes on our trucks so we can get your water back on fast.

The submersible pumps we install are rated for depths up to 1,000 feet, but the vast majority of residential wells in North Texas fall between 150 and 600 feet. Here is how depth affects your submersible pump system:

• 150–250 feet — Common in eastern Parker County and parts of Wise County. A 1/2 HP to 3/4 HP pump handles most residential needs at this depth.
• 250–400 feet — The sweet spot for much of the Weatherford, Springtown, and Azle areas. Typically requires a 3/4 HP to 1 HP pump with appropriately sized wire to prevent voltage drop.
• 400–600+ feet — Found in parts of Hood County, Palo Pinto County, and areas where the Trinity runs deeper. These wells need 1 HP to 1.5 HP pumps, heavier drop pipe, and careful electrical sizing.

Well depth directly affects installation cost, replacement complexity, and the importance of getting it right the first time. A pump dropped in a 500-foot well due to a failed safety rope or corroded coupling is an expensive problem. We use stainless steel components and proper safety equipment to prevent that.

After years of pulling pumps across North Texas, these are the most common submersible pump issues we diagnose:

• Motor failure — The motor windings degrade over time, especially in wells with high mineral content or sand infiltration. Symptoms: no water, tripped breaker, humming control box.
• Worn impellers — Sand and sediment wear down the pump impellers, reducing output. You will notice gradually declining water pressure over months.
• Failed check valve — The check valve keeps water from draining back down the well when the pump shuts off. When it fails, the pump has to re-lift the entire column of water every cycle, causing premature wear.
• Lightning damage — North Texas thunderstorms regularly take out pump controls and motors. A good lightning arrestor helps, but nothing is 100% against a direct strike.
• Dropped pump — Corrosion, improper installation, or missing safety rope can cause the pump to fall to the bottom of the well. This usually requires specialized fishing equipment or, worst case, redrilling.

If you are experiencing any of these issues, our repair team can diagnose the problem and recommend the most cost-effective fix — whether that is a repair or a full pump replacement.

Submersible pump work is not a side job for us — it is what we do, every day. Here is what sets Legacy Water Well apart:

• Equipped for deep wells — Our service rigs can pull pumps from 600+ feet. Many competitors cap out at 300 feet and have to subcontract deeper wells.
• Premium components — We install Grundfos and Franklin Electric pumps with stainless steel drop pipe on deep installations. These are the same brands commercial and municipal wells use.
• Honest diagnosis — If your pump can be saved with a new control box or pressure switch, we will tell you. We do not upsell replacements you do not need.
• Local knowledge — We know the Trinity Aquifer. We know which areas have sand problems, which subdivisions have declining water tables, and which formations produce the best water. That local expertise means better pump sizing and longer system life.
