fair enough - I'm always in favour of saving a bit of cash but I've got to the stage where I just want it fixed as quickly and as easily as poss...so I'm pretty happy to write the cost off! If in future I do another bathroom (which given the blood sweat and tears with this one is extremely...

It would seem a fair bit of work to do that - the tanks only just been put in when we had the central heating installed - - the new boiler is also in the loft and there'd be a fair bit of extending and re-routing pipes - Also I'm not sure I could lift it enough to gain the advantage needed (its...

yes thanks...I've just heard back from them and they have diagnosed the problem as the following "The pump itself requires a natural flow (without the power onto the pump) of 1 litre in 30 seconds or under on the hot, cold and mixed settings to operate. From the sounds of the issue that...

more info - and after a bit more investigation last night... Removing the shower head and turning pump off I have about 2 ltrs per minute - when I hold the shower pipe up to roughly where it would be when the head is in position its mor like 1 ltr per minute. When running the shower with...

fair enough - I'll investigate this. But if once its stopped you then lower the shower head it - fires up again - so I'm thinking maybe there is enough water there?

where could it be drawing in air from? and how would i fix this?! Sorry for all the questions!!

yes apart from the built in isolation valves on the pump there are isolation valves on the hot and cold feeds (the type with the wheel you turn rather than the ball-o-fix) type. Would all the pipework have to be 22mm or just to the pump (the pump has 15mm connectors though)- otherwise all sorts...

I'm pretty sure the tank is ok (its been recently installed as new and was spec'd into the project (although I will check this) - I'll give the 1ltr/min check a go tonight when I get home. What should I do if its not up to that rate?

probably no longer than ten mins - but it doesn't always shut itself down - most of the time it gradually loses pressure to an annoying level - although we've only used it a few time since commisioning on Saturday. Don't think I can hear any air around pump (although what would this sound like...

cheers for the speedy reply I guess the bathroom is about 2m away from the airing cupboard. All pipe work is 15mm. I reckon there is maybe 2ft of head between the cold water tank in the loft and the showerhead - could I still need a negative head pump for that? Is it possible air in the...

Please can somebody help me?! We've recently fitted a new bathroom and have installed a Salamander RSP50 pump (in the airing cupboard) connected to a Grohe Grohtherm 3000 Bar mixer shower with a Grohe Movario 5 shower head onto our gravity fed water system. When we turn on the mixer the...
