What should I do if water pressure is very low?

First, check if the water supply valve is closed and if there are any leaks in the pipes - those are the most common reasons. If everything's fine, call your management company, it could be an issue with the building's main water system.

We had the same issue in our house :( First check if the shut-off valves at the inlet are open and whether the aerator on the faucet is clogged - sometimes just cleaning it helps. If that doesn't work, the problem is most likely in the riser or supply pipe, then you need to call a plumber or the management company to figure it out. I'd recommend first calling the neighbors above and below you, maybe they also have low water pressure - if they do, then it's not your problem 😅
