    Maximum slope of underground drain

    Thanks guys. The slope is about 20 degrees on average and about 20m long. I'm already planning back drop manholes in places but I want to make the most of what pipe slope I can. As the article from Softus shows, for less than 1L/m use minimum 1:40. What I am after is the maximum. The word...

    Maximum slope of underground drain

    I'm installing a new foul water drain fed by one shower/toilet/sink for occasional use. The guide lines I've read for this application either say 1:40 or 'minimum 1:40' slope on the drain. I know that solids can get left behind if too steep but nowhere can I find a figure for the maximum slope...

    Pressure reducing valve quality

    Are there good makes and bad makes of PRVs? Are there reliability issues? I'm fitting a PRV as we have over 5bar water pressure but don't know if I need to go for/avoid particular makes. :?

    Capilliary feed fittings

    I also understood that solder had to be lead free for drinking water. Are Yorkshire fittings lead free?

    Creaking pipes

    Thanks, I'm already using hair felt in notched joists, this is running along between the joists on a 6m run, so plenty of expansion. We have full access as the ceilings underneath are down so I can clip at correct intervals if that is then going to be creak free.

    Running Combi boiler without rads

    Thanks for all the interesting discussion! I've checked with Halstead and they are quite happy with the 4m of 22 mm pipe that will make up the total central heating system with the 2m flow joined to the 2m return at the end. The idea of just shutting off at the cocks wasn't pursued as they...

    Creaking pipes

    Do standard nylon clips creak as heating pipes expand? I want to install all the pipes creak free and any advise will be much appreciated?

    Foam gun?

    Thanks, do the hand cans come with a nozzle or spout of some sort to get it where you need it?

    Foam gun?

    I'm fitting new wooden windows into not too good brickwork and want to seal the gap with expanding foam. Is it much better/easier to use a foam gun and gun grade foam rather than just the cans?

    Running Combi boiler without rads

    How about a few metres of 22mm pipe?

    Running Combi boiler without rads

    Is it possible to run a combi boiler without the radiators so that we can use it for hot water whilst all the rads are being installed at a later date. I assume this would be done by linking the flow and return pipes together and having the heating demand switched off. The boiler has an...
