Bath filler

[Andy Dee]

Hi, I could do with some advice from the group.

I have just fitted a whirlpool bath which came with all taps/fittings. However, the flow-rate from, especially the hot tap is pathetic.

All fittings are 1/2" BSP and the bath was supplied with 15mm flexible hoses.

The hot water system is a storage type and the old bath and taps were

3/4" BSP and worked just fine.

The idea is to remove the fitted taps etc. and replace with some that don't restrict the flow and have 3/4 BSP fittings so I can use 22mm pipe for the hot feed.

The present fittings are the 5 hole variety.

Could anyone recommend a supplier for 5 hole fittings that will work at low pressure?

That won't help, as bath taps are normally 3/4" (as you point out further down in your post). Also the 15mm flexies only have a bore of approx 8 to

10mm therefore restricting the flow somewhat. As you have a gravity fed HW system you really need the feed pipe (hot) as large as you can get it, the cold is mains fed (I presume) so if you pressure is OK then that can be left as is.

OK

Is the existing pipework 22mm and then reduced to 15mm to take the flexis?

I don't understand this terminology sorry could you elaborate or point me in the direction of a picture?

See above

Cheers

Hi John, thanks for the reply. Yes, the hot feed is 22mm adapted to fit the 15mm flexi. I know it would be better to keep with 22mm all the way to the tap but its fitting is 1/2" BSP.

Low pressure fittings - especially of the style you may want - are becoming difficult to find and likely to be expensive. Unfortunately the simple answer is to fit a pump.
