Push Fit Warranty

I got called out to a job about 6/7 yrs ago. failed osma gold push fit under sink in kitchen.Luckily the lady was in her kitchen when it went cos they have 6 bar cold mains!.i got paid by osma to replace all fittings in the kitchen, ensuite and bathroom. they said that they knew about a bad batch.

 

The fact that they can't be used for gas speaks voumes for me.

I have a feeling that is more to do with gas regs than suitability, we have been using JG speed fit on compressed air and non flammable gases for years in the brewing industry.

 

Used JG Speedfit to provide outlets around my previous workshop for compressed air , totally reliable.

 

Cant be used on gas in a house for one simple reason, it plastic, if the house catches fire it melts. you then have gas escaping into fuel a fire.

 

Not wishing to be pedantic Mr Dave , but surely the solder would/could melt, and we have the same scenario?

Or is it the time scale as well, takes longer to fail, possibly?.

 

I think it's probably to do with evacuation,true the solder on a fitting would melt but you'd need more heat which would take longer to build up,hopefully by this time the building would be empty.

 

Im of the understanding that they cant be used due to gas being at low pressure , not high enough to stop you pulling the fittings apart when under pressure, like what they are with water.

 

Almost the entire gas networks under our feet are now plastic (MDPE) the joints are moulded so they are nothing like the pusfit scenario.
