I suppose saving a few quid is worth more than your kid's lives if anything were to go wrong........ probably won't get your house re built on the insurance either.
Just saying.
Land registry will tell you who owns the property. Will cost you £13 ish
Or try a Google for rental property, it may give you letting agent details. Contact them and ask the landlord to deal with it
Problem is, tenants may get arsey and act worse. Environmental health might be interested but...
Nothing unusual about that part leaking, quite common. Usually because the boiler has been installed without a shock arrestor. Relatively easy job. Might be a good idea to do the right hand block too, with a new flow adaptor and silencers.
Not as cheap or as easy, and fit a shock arrestor too.
You never mentioned the salus controller or stat you have fitted.
A please or thank you appears to be missing from your posts too.

All of the showers will have nrv's built in. If they are bar showers it's easy to find which are passing. Run the shower on fully hot, feel the left inlet pipe (usually hot feed) it will get hot. Turn shower off. If the nrv is faulty it will go cold pretty quick. Repeat with all of them.

restrictor elbows serve a purpose and the associated pipe work is more robust than copper weaving its way over the hearth etc, plus it looks like it belongs there. its the way it used be done.

not that familiar with GW tbh, only done a couple. I would assume that there is a parameter that tells the boiler 'what type it is' system or combi etc.
therefore dhw preheat wouldnt come up in parameters as a choice if it was told it is a system boiler?
Ive done it myself, was on the phone to...
