Is PigletJohn still around these 'ere parts?

I have a question about water pressure and rooftop communal water tanks!

maybe.

A-ha! You are still around!

So we have communal water tank on the roof for cold water and for a while not it’s been a bit odd in the kitchen - when you turn on the cold tap it spurts then goes to a trickle (so you have to turn the tap on more). The hot water is fine.

Now the dishwasher is being a git. The rinser arms aren’t turning (have tried cleaning them and the filters) and one possibility I have read is low water pressure. I’m wondering if the two are connected in some way?

the dishwasher has its own pump to send water to the spinning arms, so will not be the cause. Clean all the filters and look for broken glass, rice, sweetcorn kernels or other material in the sump or arms. Your instruction book will tell you how to remove the filters and arms for cleaning.

Initial good pressure at the cold tap (are you sure this comes from the tank? If you are in the UK, drinking water taps should be fed direct from the incoming watermain.) that then reduces, suggests to be poor flow, perhaps a blockage in the pipe.

Ok I’ll do a more thorough clean of all the bits - but none of the 3 arms are spinning and the tablet just sits in the handle of the top rack for some reason and doesn’t dissolve (if there is any debris on the door, that is still there after a cycle). The water is defined heating up and flowing into the machine. It’s just not spraying around..

. Yes the cold water is definitely via a tank on the room (block of flats). In the U.K.

So you are drinking rain water that's been stored on the roof???

🤮🤮🤮🤮

You can't be that would be illegal surely!

No not rain water and dead pigeons! It’s being piped in from somewhere - the mains I assume - (last time they serviced it the forgot to switch it back on - then we all got flooded when they switched it back on, before realising that they’d knocked a hole on the bottom!). That was fun. No electricity for 3 days.
