I just got a new boiler fitted a few weeks ago and I'm pretty certain the guy cut every corner possible. The system was not flushed, no cleaner or inhibitor was used and the core for the flue was eyeballed without a pilot hole drilled.
The condensate drain goes into a PVC pipe that was previously used for a kitchen sink (kitchen was relocated by the previous owner). There's no trap on this connection and the fitter has branched the PVC pipe with an open end and placed the copper pipe of the blow off / PRV into this to avoid drilling another hole through the wall (picture attached). Getting some funny smells in the room occasionally, which I'm assuming is sewer gas so I'll need to install a trap somewhere.
Also been bleeding the rads regularly for the last week as a lot of air was left in the system (my CH pipes goes into the loft space before dropping back down to supply the rads from below) and the water coming out the bleed valves is black. The guy installed a Spirotech filter and I've been flushing that occasionally too and the water that comes out is full of little black bits.
The cold feed has been placed on the flow side, if I isolate the return on the boiler and open the cold feed (while keeping an eye on the pressure gauge) would i be able to use the Spirotech as a drain point to flush the system? All the rads are connected on 8mm microbore pipe, would this be likely to result in a blockage?
Finally, would I be able to connect the cold feed with an external pressure gauge to the Spirotech and use the fill point as a drain to do a backflush (after removing the non-return valve) or is backflushing unnecessary?
