90mm water mains

[tolly]

The job im on at the minute has had a 90mm water mains run into the building which I need to
put a stop tap and double check valve on for water board to inspect and then connect up.

Its massively oversized for what its serving, 32mm would have been plenty.

The biggest mdpe ive ever worked on was 63mm, can 90mm be dealt with the same, i.e I know philmac do a 90mm to 3" female iron adapter and plasson do the same but also do a 90mm to 2" FI adapter.

I only need to come off this in 28mm so could I use the above plasson fitting and then a 2" to 1" bush and an inch male iron then 28mm to a stopcock?

Or is 90mm normally done with fusion weld flanges etc

Me neither, i went to ask when they were bringing the water main in so i could valve it off etc. Site manager said its in, i said no its not theres just a duct there... turns out what i thought was a duct was the water mains, which has been concreted in the slab, no duct lol.

You can use mechanical fittings

Any over 50mm is meant to be chlorinated before water companies will connect.

I assumed u could use a mech philmac/plasson FI adapter type fitting on it then mapress off that but I suppose I wanted to know if commercial boys would see this as a bit of a bodge rather than using fusion weld flanges and coming off of that, if thats the proper way to do it then I would get someone else in to do it.

Philmac 90 mm to 2 or 3 inch copper then stop tap and dcv don't forget your drain off you can use a lever valve if you want and nope not a bodge, only normally use welded under ground as it can't be dissembled

Waiting for the water board to do an inspection first. Picked up that plasson fi adapter from drain centre in luton, very nicely engineered those larger plasson fittings, better than the domestic sized ones.
