What fittings are you talking about? The plasson/philmac are mostly compression types.

I see that a stop tap is mentioned? They would normally be in a toby/stop tap chamber. Anything brass that is to sit underground though, as mentioned, needs to be a DZR type but they aren't cheap. This is due to the addition of zinc to stop the brass corroding.

Thanks yes the plasson underground fittings

Noticed they now do the pushfit variety of 25mm mdpe fittings. Imagine the compression ones have been more tried and tested

They spend a lot of time on R&D so I guess they wouldn't have introduced a push fit version if it wasn't suitable. That being said I always use the compression types as it's what I've always used

Thanks so I have plasson fittings compression 15mm I split these and hand tighten and abit more with a pair of grips?

Yes, just make sure the seal/O ring/grab ring (material dependent) is set correctly. I do believe Plasson do a tool to tighten their fittings but a couple of good quality pairs of grips should do the job.
