I am a customer having issues with a contractor supplied Wickes bathroom install and just getting a few of my points together when the area manager arrives tomorrow. A few plumbing issues are:

The hot water is via a gravity fed stored hot water tank. System boiler in the loft. Bathroom on first floor, Stored hot water tank on same floor, cold tank one floor up in loft.

Should they of fit full bore isolation valves. The hot water in the bathroom was never that great. And will now be using waterfall taps. The valves they have fitted look standard restrictive?

Should I be asking for a swap? I am assuming the arrow should be correct direction as well? Also other pic shows they added a iso valve to the WC inlet pipe. The pipe has quite a bit of play. Potential water hammer? Should they of removed the gate, full ball lever valve and clipped to wall?

Tiler removed old central heating towel rail. They didn't have to drain rad. Previously it had two isolation valves where the black tape is on pic. Is it likely if he didn't touch heating that he closed valves and simply removed. I am assuming if the iso valves are now half buried under the FFL its a bit of a cock up. I seem to remember iso valves are not rated to heating temps and will almost likely leak once tampered. Should he of drained system, removed valve, soldered new pipe and away from wall. Yes its all cowboy I know. He didn't even install a trap on the bath.

Thanks

On gravity - definitely. Although with waterfall taps it probably won't make a lot of difference, they are inherently shyte low flow things anyway - assuming they are even suitable for low pressure, which they probably are not.

As for the rest:

1st picture - only a moron would tile around an isolation valve so it can't be accessed. 'skirting' tiles with an unfinished edge uppermost? Tiles are so close to the valves so will be difficult or impossible to connect anything to them even if they could be opened.
2nd picture - no trap which is required, and a vast amount of PTFE tape which is not. White pushfit with the braided hose either hasn't been pushed on far enough, or they didn't cut the pipe at one of the cut marks.
3rd picture - rolls of PTFE tape strike again (none required) and why are there the remains of destroyed push fit connectors left on the pipes?
4th picture - isolator installed backwards, expect it to leak.
5th picture - gate valve should have been removed, and someone has bodged an isolator onto what looks like a tap connector. That will leak as well, because the sharp edge of the isolator will slice into the washer in the tap connector. Yet another entire toll of PTFE used where none is required. Black flexi connector thing below isn't needed either - on a new bathroom, the whole pipe should have been replaced if it wasn't long enough. Short vertical white plastic pipe is for what?

An entire shambles in just about every way possible.

Should I be asking for a swap?
Asking for the whole lot to be ripped out and started again by people who actually know what they are doing would be a more likely option.
Difficult to see how any of that could be rectified properly without redoing the entire lot.

Thanks adds more ammo when wickes come round tomorrow. I put a post on the tiling forum as well and had a lot of responses like this there. Good to get the plumbing side of things.

Look at the FFL. The floor SFL on the previous bath install was same as adjoining room and good nick. Think they laid on previous ply from Vinyl.

If i remember the short white vertical pipe was the overflow wast from previous toilet
 
You can have a look at the video of 5 days worth of work here. Any other issues spotted let me know. Much appreciated.
