terryplumb, thanks for all your input, really appreciate it.. I know they done nothing to the pump with respect to cleaning any internal filters out.. they made that clear when we challenged them on the problems.. they said they just connected their pipe work to the push fittings and that was...

Yes, that method of starting shower works but after a week it won't work. Basically this has been the way they have been activating shower previously before the refit but it was constant without any issues. Since the refit the method works for about a week then no hot water. I have come round...

The pump is a grundfos SSR 1.5 and only supplies hot to the bath tap (which is a standard tap physically separate from the cold tap) and the shower mixer. From under the bath you have the gravity fed hot feed coming into the pump then the pump output is connected to a T piece with one leg going...

I may have misled you there although I can't be certain until I verify whether it is mains fed... There were occasions when trying to get this working where the cold wouldn't work as well as the hot.,, however, this morning when I popped round there the cold was working but not the hot... I...

Ahh ok, thanks for clarifying that.. I've had them out of both sides a week ago (if you mean the hot and cold inlet feeds to the mixer bar), the hot was clear but the cold had some minor contamination most likely from a rough cut of the plastic speedpipe they fitted on the cold side.. only a...

terryplumb, I'm almost certain it is mains fed cold but will verify when I go round the daughters house again tomorrow.. I'll isolate the cold feed, set to hot and see if it flows once the pump engages.. makes sense this test.. Thanks Is there any mileage in trying to balance the cold feed with...

I've tried that with the shower laying in the bath but doesn't have any effect. I think you"re right about the head pressure. I've got a feeling the unit they fitted is a 2bar pressure requirement. I've seen units that operate between 0.1 - 5 bar, reckon I need a lower pressure one.. thanks

Thanks footprints.. I isolated both the hot and cold from underneath the bath with those lock off valves on both feeds. The shower pump has just two connections in and out for the hot.. Update; I've just been round there after reading your first post and with the water on undone one the big...

From what I remember the connection to the mixer is straight from the wall but will check.. not sure about the venting sorry? The pump kicks in but will not kick in by just using the mixer water control.. we have to run the hot water tap in the bath with the shower set to on then back off hot...

Hi, Recently had a horizontal bar mixer fitted at my daughters house shower as part of a bathroom refit. Having trouble getting the plumbers back round and we have an issue with getting any water out of the shower. I have had the mixer off the wall and replaced and it then works ok for about a...

Ok Vaillant boiler man turned up this afternoon and got stuck in. Was puzzled there wan no error codes and called Vaillant. I then told him that the boiler can me made to fire up by applying a little heat from a hair drier to the PCB (a trick I have used on other equipment that I'm familiar...

Appreciate the advice Dean, Vaillant boiler are coming this afternoon so hopefully will get sorted. Had the f.75 a while back and had the two pipes with rubber hoses replaced with copper and sensor position moved to top of pipe.. all worked good for a while but now this problem. Regards

Thanks |Dean S.2 then S.97 It was cycling like this yesterday for about 2 hours fired up and worked all day then same thing again this morning.

Tony, Agreed, I have an registered Vaillant engineer coming tomorrow to have a look. There are no status codes shown on the screen expect for the radiator and pump symbol when it attempts to fire. Regards

Hi, I have an ECOtec Plus 831 that has just stopped working.. Basically, the boiler pump starts running and the radiator sign appears with the pump running sign in the window but the boiler won't fire. There is an initial whir of the fan as it tries to fire up but then just cycles back...

yeah there was crap in my system probably making the diverter leak, there was like this black crud in the holes of the heat exchanger and in the diverter valve. Finally got it cleaned with x800 and a magnetic trap. Reckon the original fitter never power flushed properly or dose the system.

My diverter valve is leaking and needs to be changed out. I notice that are two versions of the diverter available. Is the updated version anymore reliable than orginal which apprears to fail quite regularly and is a known hassle with this boiler? Cheers

Changed the pump out today for a new Vaillant / Grundfos model. The old pump didn't look too bad but had a little lateral play in it but no side to side movement from the bearings. Was a big blob of limescale in one of the impellor water ways as well. When I removed the old assembley the lower...

831, There's some evidence of a leak underneath the pump area, so i don't know whether it expelled water and sort of sealed itself because it's dry at the moment.

if you mean on the rads i've got TRVs but most of them are off because they're a pain.
