For several days now, I have noticed that the water pressure changes periodically—sometimes it is strong, sometimes it is almost non-existent. This is especially noticeable when I turn on the shower. I suspect that the problem is either with the filters or the pressure reducer. Does anyone know how to determine the cause on my own? Or maybe it's better to call a plumber right away to check everything from the riser to the faucet?
I am also concerned that such instability may affect the operation of the washing machine or dishwasher. I tried cleaning the aerators and filters, but the improvement was temporary. It would be useful to know if it is possible to determine the cause without special equipment, and which technicians perform comprehensive diagnostics in such cases to eliminate the problem once and for all.

I had a similar situation—the water pressure kept fluctuating, especially when using the shower, and I realized that it was difficult to determine the exact cause without special equipment. The problem could be in the filters, the reducer, or even the riser. To avoid constant temporary solutions, it is better to turn to professionals. I used drain cleaning etobicoke they performed a comprehensive diagnosis, checked the entire system from the riser to the tap, and eliminated the problem once and for all. Now the pressure is stable, and the washing machine and dishwasher are working without interruption. Such specialists really save time and nerves, because a comprehensive approach helps to solve the problem effectively and reliably.
