just as guess i think you have tank fed open vent hot water cylinder and nows a mains cold feed on the mixer. may need a Pressure reducing valve on the cold feed and a single check valve on the hot feed to the mixers. Also could think of getting a combi?? or a unvented hot water cylinder...

as dan says he may have forgot to connect it up outside. i was only pointing out if he was in a 'rush' and he knew that the tiler was going to be on site before he could connect it up then he may have connected this pipe to the bath so the tiler could tile around it nice and neatly. (common if...

yea would defo say use the balanced cold connection on the combination valve off the megaflow. It will be blanked off as standard i think? But run it from there same if you have a mixer on the bath could be worth taking cold feed from there to.

stop tap may just need the gland nut nipping up.

yes you should defo ask him back to fasten it wall explain that the sealent has come away and the appliance is not installed to manufactures instructions or approved code of practise. He may have genuine reason so dont take this as open season on a cowboy. Just give the installer the benefit of...

sounds like a mastic queen, or stick like ****. might be ok but a proper hassle if it needs removing for maintance or replacing (tiles and all stuck to the sink). not a very neat job but will do. as for the leaks may not be job price but he should have made you aware that it needs repairing at a...

well they could if they are feeling brave cut the olives with a junior hacksaw and use screw driver to snap them off then replace the whole assembly. Or they could buy the tool to remove olives. Just dont forget the plumbers tape for everything.

recommend that you ptfe tape on olives too

have you tryed so elevate the joint to stop it running? Then use the heat gun to boil the water out. If there is no steam then let it cool then dress the joint for soldering then solder it elevated

This might be becuse heating should be zoned at so that each zone heats a maximum area of 100m2 i think.. dont know how big your extention is nor am i defending the plumbers. Kettling could be due to the constant venting pulling in air causing air locks? might be worth having a think at...

as title. Topped it up still get a trickle out the lets thought might have been frozen so been checking over last few weeks no change? Is the pump knackered? Do you think that could be due to freezing? Car is a hyundia accent r reg

never say never. Although i would say if new or quite new them it is less likely (my fault misread) it should have been checked at time of install. So i doubt it just a thought though and it Wont have0cost you check. So it was a cheap option? Hope you find it soon.

have you considered that you may have a faulty pressure vessel or it may just need re-charging.

yea like kirk says t bend blockage. Specialy if the mrs uses moist towel to freshen up. They are a pain in the arse. Even been called out to one outside blockage need to dig up pipe thought it was blocked pair of old knickers. More recently i had one freeze on a 90 bend had a small leak that...

also im not sure if you have but you need some form of essex valve on cylinder.

you could try and put and put 15mm auto air vents on the got and cold were it bends down from loft into bathroom. But i suspect your pump my be set up wrong positive and negative pressure. Read instructions might be able to switch it over some have a dual pump. Some are self sensing.

im taking it that the pressure vessel is for the ch not your hot water. In that case your got water storage vessel is gravity feed. Try checking the cold water storage tank in the loft to see if the ball float is stuck or not opperating correctly. If not could be possible blockage on the...

well i did check the pressures at mod valve test points everything seemed fine.
