Little update- I tried it on a bit of identical brickwork in a lean to shed. The patch on the left has the primer (you can see at the bottom) and then paint and on the right its just paint straight into the brick. The paint is one coat of bog standard magnolia emulsion and there's basically no...

Hi all, I've got a brick corridor leading to the garage that I want to paint white. This will be demolished in a few years so don't want to invest too much in it. I also have a full 20l bucket of 'Cromarty building products Hi-bond primer' left by the roofers when they felted over an ashphalt...

Update. Looks like this is solved. The builder purchased and fitted (no cost to us) a new shower tap unit several weeks ago and now it works fine every time on both handset and rain head. The pump consistently kicks in straight away. It really does look like this was all caused by debris from...

It was never right from day 1. We always had to fiddle about with the shower controls to get it to start the pump and then it would fail soon after. Yes, we are aiming to get it replaced under warranty but it was ordered on the builder's account so they supplier will only speak to him due to...

A further update! Yesterday afternoon, after the spare unit was fitted, the overflow pipe from the loft started flowing and on inspection the header tank was overfull. I thought the water was slightly warm but put that down to it being roasting in the loft. The flow stopped after having a...

Another update and potential solution! It looks like the problem could be something nobody thought of! They came back yesterday with a different shower tap unit to test a theory about pressures. This one only has a handset outlet, not one with a rain head as well like the existing one that...

It's 2m absolute tops at the moment.

Oh. where should it be then? The current one (that doesn't work properly) is....

Yep, it's looking that way. Would I be right to assume a universal would do the job the same as a negative head? Only issue with those, apart from being about twice the price is that they tend to be taller and so might not fit under the bath.

Quick update: They came back last week with 2 men, removed the bath panel and tested the pump. Nothing wrong with it electrically. Then they reduced the CW flow going into the shower mixer. That allowed the pump to kick in if you briefly crack open the HW tap to the bath. That worked for 2...

Thanks Rob, I've tried your test a number of times this morning and no joy. No difference at all under any circumstances and the pump definitely does not kick in. To satisfy my curiosity, I did check the fuse and it is indeed fine. I note everyone's comments about a negative head pump being more...

I hear you Madrab! I will try that test and report back. We almost never used the rain head but what I don't get is that until recently, this set up did work (generally by turning on the shower full on in either rain or handset position then putting the thermostat handle to full cold then...

Just tried that John and removed the hose and handset, nothing happened. I tried with various settings of all the taps but the pump didn't kick in. For reference, these pics show our setup. The HW cylinder is in the airing cupboard with the louvred door, right next to the bathroom. The pump is...

@Johntheo5 the bath hot tap supplied by (horizontal...) gravity from the HW tank in the airing cupboard adjacent supplies 4 litre pm, calculated using a measuring jug and stopwatch.

The bath HW tap is fed direct from the HW cylinder. We had been using the bath CW tap to force the pump to start. That was working for a while but now isn't.
