The pool pump makes a strange hissing sound? The problem probably comes from faulty ball bearings. It only takes 2 hours and a few euros to replace them, provided you have pull-hubs.
Pool pump to repair
A pump is essential equipment for the operation of a swimming pool
It sucks the water at the bottom through the bung and on the surface by the skimmers, returns it in a filter through separate conduits each equipped with valves, then expels upward, free of impurities, by the discharge nozzles . All these elements create a continuous movement of water, which keeps it clean.
A pool pump: how it works
The filtration pump consists of two parts: a pump body with a turbine that allows the suction and discharge of water and, at the front, a prefilter (basket) that recovers “waste” that can damage the blades of the turbine.
The motor (electric or thermal) is, meanwhile, screwed on the pump body.
Thus coupled, the motor shaft can rotate the pump impeller. The engine is cooled by a propeller located at the rear of the block.
Warning signs of the breakdown
In our example, the engine with a power of 0.55 kW allows a flow of 8000 liters / hours. The ball bearings consist of a two-crown structure between which steel balls inserted in grooves roll. They serve to prevent wear of the rotating shaft and its support, and thereby the heating of the engine.
The first signs revealing a failure of the ball bearings are the presence of run outs (rust color), at the level of the engine block, associated with a persistent hissing. With time, the engine vibrates.
Conclusion: it no longer drives the mechanism and the bearing or bearings no longer play their role. Another possible situation: the pump operates, but the balls come out of their housing and deteriorate the rotor or the winding in the case of an electric motor.

Savings in spare parts
In both cases, it is necessary to change the damaged parts.
They can be ordered in specialized stores or on the Internet (www.abc-roulements.com, www.conrad.fr …).
The repair took place here in 2 hours and at little cost (6 $ the turnover).
Indispensable to intervene on the bearings, the pull-hubs can be bought for less than 30 $. A low investment is compared to the price of a pool pump that ranges from 100 to 600 $.
Practical Advice
- It is not uncommon for disassembly, strongly oxidized nuts and screws to deteriorate or, in the extreme case, break. Considering their cost, place them without hesitation or if you do not have the necessary tools, reproduce threadings and threads.
- To avoid mistakes when reassembling, do not hesitate to photograph some details: electrical connections, order and position of parts.
