Trying my best to do as much myself as possible so excuse the silly mistakes I’ll be making along the way. Just fitted a new bath and am mid bathroom renovation. The bath Taps the wife chose upon fitting had 1/2 bsp tails, all I could get was 15mm to 1/2bsp tap pipe adapters not 22 to 1/2 bsp, so changed my pipe work accordingly (see pic)  possibly not to my advantage. Anyway now, and probably obviously got lower pressure at the bath taps. Apart from buying new taps, re drilling the bath tap holes and replacing the pipes to 22 and 22 to 3/4 bsp fittings are there any other solutions or advice? Added some pictures but please don’t be to harsh, I thought I did well lol.. I can live with the slower taps but maybe do it now in case it annoys me.. 

It’s not the pipework, it is those lever valves you’ve installed - they have very restrictive flow rates. 
 

15mm into a bath tap for that short distance is fine but you want full bore flexi hoses for the connection.

I thought I was playing safe! Many thanks will change these tomorrow. 

In future, best way is run all in 22mm and then reduce right at the taps. 3/4 to 1/2 hexagon reducers are pennies. 

As mentioned above those valves will be restrictive along with your flexible tails too possibly. 

 

Otherwise don't be too hard in yourself it looks a nice clean job. Well done.

You can get full bore 15mm isolation valves, but can only find compression types.

If you can't find what you need, then you can get a pack of 2 15mm fullbore isolation valves from SF, then you a plain 1/2 -1/2 tail or 1/2-3/4 whatever you have on your taps.

Advice taken. Thank you 

Thanks for all your advice. Here we go with a quick change 

those flexys don't look terribly big bore?

22mm to 3/4 bsp 

the internal bore of the flexy is much less tho, and some are better than others. Those looks like JG ones, so the hose is only 13mm inside.

 

Whilst eg BES item 13753 is compression, it's also 19mm bore, much better flow

Best way to learn! (Seriously; I find you learn far more from your mistakes than your successes, particularly if the latter are accidental ones!)

One suggestion I would make is to shorten the overflow pipe... Not only does it keep it out of your way whilst working but a dip might catch some dirty water going down the plughole and end up causing smells.

Is this gravity hot water from an 'old-school' copper tank, or pressurised from a combi / unvented cylinder?
