The vessel is a red one and came with the Heatrae Megaflow unit as a packaged standard option (not tailored for the installation but what would be generally suitable) for converting the CH system to a closed system but not meant for the megaflow unit itself. Sorry 45yagm, I didn't look at...

About 2 years ago when the loft was built and a megaflow installed, I had my gravity CH system converted to a closed system. The boiler, a Worcester Bosch CBi24, remained as it was quite new and suitable for a closed system (the megaflow system came with with an expansion vessel of 8 litres)...

hmmm...I've read the section on calibrating the by-pass and although it's concise and looks a simple task, the whole setup with all the pipes, valves and dials looks intimidating so I'm a bit nervous about undoing the valve in case I'm in a situation where I find I'm out of my depth and have...

Thanks for the link greemyamochop. That's exactly the system I've got installed. I've checked my megaflo and there is the bypass valve illustrated in the diagram on pg 30 (it has a green plastic top that moves quite freely with a dial and numbers!?). When in normal operation and CH heating is on...

Matthew I think there may have been a by-pass valve before the megaflo was installed. This megaflo unit came as factory pre-assembled with all the pipework, valves, pump and various other gauges, release valves etc. all neatly attached around the megaflo and also with programmer, room stat...

This problem started happening only recently. It happened for a week or so last month then stopped and now it's started again. The installation is a Worcester Bosch boiler installed some 5 years ago in a gravity system. The system was converted to a closed system when a megaflo was...

I had a megaflow system installed a year and half ago when the gravity system was converted to a closed system - boiler is a Worcester Bosch 19/24. Everything worked fine. Some months later I had a loft conversion done and added 4 new radiators (one a towel rail). Two issues arose. One: The...

Well that's re-assuring - maybe I'm being too concerned. Because of this have barred this WC for big jobbies (there are others in the property!). Hugh, if the join can't be undone, splicing the section is an option but something I really would like to avoid. My builder put that tile...

Oh dear! I was trying not to think about that possibility! May have to check with the plumbing company whether the joint was indeed weld joined. If that is so, how can the joint be freed? Still using straps - with extra muscle? Softus takes no prisoners - you escaped with the word 'nearly'!

I know what you are saying about pinning it to the wall with brackets. The pic perhaps does not show it clearly, but in this case the pipe is not along a wall so the support has to be under it. With the support it has, the builder was even able to stand on it trying to free the join. But I...

So if the pipe is straightened at the joint, making it as if it were one single length of pipe, there would be an even fall along it's entire length. The pipe is supported from underneath, so an extra support would be placed under the join.

Thanks Goldberg I'll get my builder to try it using straps. I know it doesn't look like it from the pic I posted before so I looked around and found this pic which shows the complete run. I just looked and the fall is within the parameters as you described. The installation was...

This is the best I can do. The pipe runs along the top of the first floor flat roof. Picture taken from window above. To get the best perspective, I'd have to go to the far end of the flat roof which is difficult for me to do. The builder put the roof tile under the join for leverage, but...

About 6 months ago I had a new WC installed. On the black plastic soil pipe run outside the property, as the pipe length was not long enough a connector and an additional length of pipe had to be fitted by the installers. I noticed recently that the run is not completely straight as the pipes...

Thanks again. I was concerned about the adhesion, so I called the manufacturers and discussed it with the technical guy. He has suggested that the best method, even better than gluing, is to use screws. The company has screws specifically designed for T&G and engineered woods floors with a...

Thanks - and yes the instructions did mention that nailing to chipboard was not ideal as the nails may loosen over time. For the bonding, would it help if the floor was coated with PVA or something like that before gluing down the floor? Also what about the provision for expansion, is it the...

Have had a new loft built. The floor base is 18mm water resistant chipboard. I am going have a solid oak tongue & groove 18mm floor laid on the chipboard. I have purchased the flooring (Elka) and read the installation instructions. There are two recommended methods of laying this floor...
