Managed to disassemble PV.
The heater itself after 13months with polyphosphates looks worse than the previous one without them! (not just scaled, pitted with rust too)
Need softener, period.
Can you recommend one?
Ideally slim vertical to fit behind PV, or in the cupboard next to it. 2 people 2 bathrooms...
NB Tectite brass pushfits in hard water area are fun to disassemble...
Hi yes it is trench fill
But in my notes from the architect it says that its cavity filled with concrete to either 225mm below DPC or 150mm below, im not sure which is rigt and why it states 2 differing options
Im getting ready to pour my concrete into the trench weve dug. The trench is about 1m deep, the building notes say 700mm conrete into that, then build the substructure from either 7n concrete blocks and or engineering bricks.
Seeing as laying the initial first courses in the superstructure is slow and time consuming (ie expensive as i cant lay bricks well) im wondering what the maximum depth of concrete i can pour in? i know the engineering bricks/blocks have to be filled with concrete to strengthen them, but am i determined by where the DPC will be and the concrete cavity fill has to be a certain depth below the DPC?
Can i put more concrete in and save a couple of courses of bricks?
