Glue... damn plastics
« on: August 26, 2017, 07:16:34 PM »
Hi Guys - new here, and just put brushes in my DC04, so thought I would give it a clean too.

I took the cyclone assembly (45) apart and removed the valve that is in there - and one leg of the silver cyclone moulding cracked... bu**er....

So - what kind of glue repars Dyson plastics?!!?

One of the valve clips broke too - plastics are so damn fragile.... I can evostick that back in I am sure and it wont show and probably will never need to be removed (cant quite work out how it works anyway!).

Thanks in advance

David

Pipe weld is OK, of the type plumbers use for plastic waste pipes. Evo do one too.

Araldite is OK depending on the application.

Regular Evo or normal glues tend not to be ideal.

Excellent, I had not considered that, and even better, have some already!

I did think about old "airfix glue" - but thats rare these days it seems!

I assume the pipe weld melts it, so will be very strong.

I think I will use evostick for the valve, just incase I ever have to remove it...

BTW - how do I test the valve? - if I gently blow in the wee side entrance, (ooh err, missus).. I can see the valve opening/closing - is that a good enough test or do I need to check its airtight somehow?

If your talking about what I call the HPR or as its well known suction release (I call it a HPR for High Pressure Relief valve) the one on the cyclone either clear or the secondary colour of the machine then I always rebuild them - put them back in and turn the machine on - block suction on the wand and make sure it sounds okay and when is in normal operation isnt hissing - ive had one hiss before after a rebuild which was leaking air via the seal. As long as it operates correctly and the suction is fine it will be okay
