Is that stopcock purely for the toilet? or is it the actual main stopcock?
If purely toilet, I notice theres two pipes running at the back of the toilet, presume hot and cold? could always "T" off the cold at a suitable position, install a service valve and a flexi.
Just out of curiosity, what baxi is it? The duo-tec is a great boiler in my opinion. Now with the added bonus of a long guarantee, 28k duo-tec is more than ample for a 3 bed home, running a single shower.
If i remember correctly, the extension hoses come with an adapter to connect the washing mashine hose (fits inside hose and extension hose, secured with jubilee clips)
7 years of constant water penetration.......not good! do the tiles come down to the top of the tray? or is the wall tiled all the way down and tray stuck in?
Are you capeable of removing the shower tray yourself? if so, i would remove it, find out whats causing the movement (slight uneven...
Have a look at the baxi duo-tec's. now come with a 7 year warranty! i know of 5 people incuding myself who have the 28kw. no reported problems as yet, oldest boiler is nearly 6 years old. only issue we have had is the batteries going flat on the wireless stat!
As with dan, if you were to run two showers from your combi, you will get a mere dribble out of both! unless you change your hot water system, i'd go electric (ensure you have a 10mm cable installed and go for the higher KW range)
I got a ferroli in one of my properties, domi compact 24. I had same symptom as you when it was first installed, theres a valve which works on magnetic contacts. Basically a bit of debris prevented the contacts mating. To be fair to the ferroli its not been too bad, touch wood! I had a leak from...
They're not that bad to drill. I presume your hole saw has a pilot drill in the middle. If not i can't reccomend enough to go buy one. Leave the cellophane on the bath and mark out with felt pen. Dont press too hard when drilling.
It would depend on how much the valve would be open i guess.
I suppose you have nothing to loose by using the sealer, and could save you a shed load of work if it works. and i suppose the pressure gauge will be your indicator wether it's worked or not. fingers crossed mate it does the trick.
I was curious if you were draining the boiler via the pressure relief valve (red cap) i was going to say if you do drain if from there, dont. as the valve can be a bugger to reseat properly.
as armo said for inhibitor, tho with the towel rad vent plug off i usually free pour in to there, but...
