Title: recent drop in cold water pressure in shower
Post by: serviens on April 29, 2020, 09:45:45 PM: Hello,
During the COVID lockdown, I wasn't sure if I can really get a plumber out, but I have a shower in the upstairs bathroom. The hot water cylinder is the other side of the wall, and normally the water pressure was perfectly fine. However, over the last month or so the cold water pressure has dropped significantly. I have no knowledge of plumbing, so hoping for some guidance here for what to check, etc. The sink taps are excellent pressure in the same bathroom, and the hot water is fine and hot, with moderate pressure. I've taken some shots of the HWC and hope someone could suggest some clues. I did notice my water bills have shot up, though I haven't discovered any leaks anywhere.
Please let me know if there's any information I could provide?
Warm Regards, and stay safe

Blocked strainer (debris blocking one of the valves)
Faulty limiting valve, or even something could be wrong with the shower mixer. Its hard to say unless you get someone to look at it really. Just get a registered plumber in to investigate.
