Low pressure around house

[davidw]

I'm trying to track down the cause of low pressure around our new to us house. I've measured the output, thanks to the advice on this forum, and its around 10 secs per litre. I'm attaching a few photos of my cylinder. if someones having a shower and I run a cold tap then the temperature changes quickly!
Any advice appreciated.

As i've said in a previous post the incoming strainer is probably blocked and possibly a faulty PRV. You need to get an Engineer in to take a look.
