Condensate Pipe installation

[Michael Groves]

Engineer has installed several boilers for me. All the condensate pipes have been connected externally into soil stack or rain water downpipe. In each case he just drilled a hole in the pipe, and stuck the condensate in the side, smeared glue everywhere. No boss, or branch.
Is this allowed, is there a regulation that says you must use appropriate fitting, or is it just bad workmanship. I want it fixed, but not sure I have an angle other than poor workmanship.
In each case, a pipe protruding into another pipe is gonna create an obstacle, surly this is not allowed ?
What I can see is there should be a visible external air break for rain water down pipe, so this is one option.
I'd appreciate any feedback, especially if there is a reg.
I've only looked at Condensate regs (HHIC), but maybe there is a water reg I'm missing ?

They are all 32mm insulated.

Thanks,

No regs in regards to connections

But very poor quality workmanship also should be insulated and air gapped if external

If rainwater pipe discharges to a combined (foul and surface water) sewer via a rainwater drainpipe trapped at the foot to prevent the escape of sewer gasses then an airbreak should probably be there to comply with the boiler manufacturer's instructions (if the drainpipe blocks, the boiler would otherwise get flooded by rainwater). Because the boiler is an approved device to whatever standards of the time... only if you install as per the MIs (which will also likely insist on minimum sizes and insulation of external pipework).

If the rainwater pipe goes to a surface water only sewer provided by the water undertaker then probably the water board will probably object to condensate being discharged into it?

If going into the soil stack, then I see your obstruction argument. The connexion probably wouldn't be airtight either and might be considered not to comply with Part H of the building regulations for these reasons. You couldn't usually fit an air break here as you'd allow sewer gasses to escape, so the boiler manufacturer may accept a lack of air break in this situation.
