Please don't shoot me down in flames for my stupidity, but I was wondering if a home-made power flush might be a good idea or not, considering I'm skint just before Xmas and my heating is crap? I've tried lots of other work, and come to the opinion that power flush is required (see my previous thread for details). So, could hire for £80'odd or could I use the cold water pressure instead?
1. Bung the expansion pipe above the F&E tank.
2. Get ready to open the drain value, via hose pipe, to drain
3. Connect cold water tap, via separate hose pipe, to the feed pipe from the F&E tank (the one below the water level)
4. Close all rads with both valves on each
5. As I turn on the cold water tap, I also open the drain valve
Surely that'd use cold water pressure to "blast" through the pipes, hopefully dislodging the more stubborn crud? It might even dislodge any air pockets or traps? Then would lower cold tap pressure, close drain valve, turn off cold tap (in that order), add inhibitor to F&E tank, un-bung expansion pipe, and you're a good'un.
Is that complete tosh, or am I barking up the right tree for a "Dragon's Den" stylee cheapo-power-flush?
