Thank you for reading this introduction.
I have spent most of my life working as a multu trades person, my work ethics are simple, be transparent to my client, be timely, be skillful, and honest.
My learning started when I was 19, I have had 34yrs experience at my job!
I started as a cabinet makers apprentice, and have worked for Lords and ladies, and Mps doing high end furniture, conservatories, refurbishment work on properties, my work also took me to learn other trades including carpentry, plumbing, tiling, and other trades.
I am currently working on refurbishment property work.
However this work is taking me too far afield and I'm a single dad so I'm looking for more local work, hense advertising on this site.
Usually the knocking is a bouncing washer in the tap, this can reverb the whole pipe, it's easily sorted as a rule

If your wiring is safe and too standard new electric rads are easy to install and probably safer in the long term however this is only to be checked by an nic registered electrician
Several issues, check if the service valve (if fitted) is on. the shower unit has power, or ultimately there's is a feed, seems obvious but it's surprising what mistakes are made, and lastly it coukd be a fault in the unit.
Washing machines are usually cold fed, your cylinder will be also, so probably can do. but drainage i can't say
