Column Pump to Sump Pump Replacement
These column pumps inside the building were not operating as they should due to wear. They were replaced with sump pumps, which are easier to repair or replace. Cover plates were installed following the sump pump installation.
Pressure Reducing Valve (PRV) Internal Failure
These PRVs show what can happen over time inside the valve! The first PRV has significant dirt buildup, which can negatively affect proper operation. The second PRV has a completely ripped diaphragm. When a diaphragm fails like this, the inlet and outlet pressures equalize, which is potentially dangerous and can lead to over-pressurization of the building and major leaks!
Megger testing of sump pump. This pump only has 4.3 Megaohms to ground when 1000V is pushed through the motor winding, which is quite low and indicates that water might be in the motor. This usually happens from shaft seal failure or leaks in the power cord terminal. Low resistance to ground creates an easy path for electricity, and eventually the motor will short and the pump will fail.
Megger testing of sump pump. This pump has very high resistance of 2000 Megaohms to ground when 1000V is pushed through the motor winding, which is very high and indicates that the pump is still in good condition. This test is important to gauge the health of the pump without removing it out of the pit.

Armstrong 4300 Pump Seal Repair
This Armstrong 4300 pump had been leaking for quite some time, causing severe corrosion inside the power frame and on the coupling, seal, and gland (Before)! An on-site seal replacement was completed, along with thorough cleaning of the power frame, gland, and coupling (After)!
Because the chemicals added to the circulating water can quickly corrode paint and metal, we strongly recommend repairing leaking seals as soon as possible to prevent further damage!
