How would I go about getting rid of the hydroscopic salts from the bricks if it was this?

I just had a look at the driveway and just where the air brick in the photo is, there is a different patch of concrete which actually slopes to the house, which I suspect may cause puddling of water (but I have never really noticed) - i'll check next time it rains (probably tonight!! :D )...

The inside floor is suspended floor boards, the low vent is venting the cellar. The dpc was done because of signs of damp inside the house. I'll have to check the dpc level inside, but I believe the dpc level outside is the equivelent of about 2 bricks height inside the house. The bricks...

It's a solid brick wall, circa 1880's terrace, so no cavity.

Its my driveway, so no drunken p***ing up the wall I hope!! :lol: It doesn't have any type of cowl on the chimey, do you think it could be too much rain getting in from there? It has three large chimney pots on top, so there is plenty of room for rain to get down I guess. But wouldn't that...

I have lots of MDPE left over from a previous project. I know it is meant to be used underground, but can I also use it for an internal run from the main in the cellar upto the ground floor kitchen? The run will be about 10m attached to the cellar wall, so it won't be burried. Any help...

Fantastic, I suspected it could have been this. There are 2 x 2 port valves, one for CH and one for HW. I will try swapping them over and see if I get the same problem in reverse i.e. HW instead of CH. Thanks for your help. Jon

Hi Guys, I have a problem with my central heating which I cannot seem to get to the bottom of. Basically the hot water works just fine, but when I turn on the CH (from cold) roughly 15 mins later the system trips the RCD on the main consumer unit. When I reset it, the CH then trips within...
