Dave g Posted July 15, 2020 Share Posted July 15, 2020 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..

PeterW Posted July 15, 2020 Share Posted July 15, 2020 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. Link to comment Share on other sites More sharing options...
PeterW Posted July 15, 2020 Share Posted July 15, 2020 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. 1 Link to comment Share on other sites More sharing options...
SuperJohnG Posted July 15, 2020 Share Posted July 15, 2020 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. 1 Link to comment Share on other sites More sharing options...
joe90 Posted July 16, 2020 Share Posted July 16, 2020 You can get full bore 15mm isolation valves, but can only find compression types. Link to comment Share on other sites More sharing options...
Carrerahill Posted July 16, 2020 Share Posted July 16, 2020 (edited) 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.

dpmiller Posted July 16, 2020 Share Posted July 16, 2020 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 Link to comment Share on other sites More sharing options...

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

Nickfromwales Posted July 16, 2020 Share Posted July 16, 2020 Is this gravity hot water from an 'old-school' copper tank, or pressurised from a combi / unvented cylinder? Link to comment Share on other sites More sharing options...
