navy unions

[REDSAW]

help in kickstarting the grey cells please.

got a std rad to be switched for a chrome towel rad and the tails are 4'' too wide.

i cant really change pipe work as it comes through the wall 't'd from the rad behind the wall just bellow its valves, plus other factors making it a pain in t bum.

what i really need to do this job quick and simple (as i want to get on with other parts of the job) is a bent union tail to 15mm so i can just fit to the valve and then on a compression to the rad as draining the whole system and re-filling is another job.
has any one seen or know of such item or other ideas how to solve the connection (i have opted out of the polish flexi by the way.lol.)

thanks.

what about a chrome angled female iron(if they make one)use a trv chrome 1/2 tail in the rad screw the angled iron into that,then your new tail in the other end

 

[tamz]

Use angled valves with half inch compression tails.
Screw the valve tail into the towel rail. Use 2 chrome compression elbows and a wee bit half inch chrome to go from the rail to the valve.

Btw on an earlier point about the price of copper from bandq.
Got some today.
30m x 22mm £129.90
30m x 28mm £99.90!

thanks tamz gas man.

but i dont want to drain down to take of the l/s valves.

does the crimping on the thread of the union seal well into an iron with ptfe or b/white well?.

 

[tamz]

PTFE will seal any thread.

Get some bungs in and swap the valves (or if a tiled or lino floor get an old towel down and just swap them). Depends how fussy the cust is if you can get away with the old nuts. If you need to change the nuts you will need to bung it.

combi's a bit hard to bung though?.

however it is a newly tiled wet room, but then it could stain the tiles maybee?.

 

[tamz]

You won't need to bung a combi. Take the case off and shut the AAV. Let the pressure off and just swap them. Dead easy and any spilt water won't stain the tiles.

Get two bent chrome isolation valves and the adjustable radiator tail extensions and jobs a good one, it will look shi!te but will get the job done

funny you mention that, i got them today from plonkerfix.

wheres the aav on a duotec tamz?.

 

[Billy Bob Bob]

aav on duotecs one on the pump one on the top of boiler,but be warned red if the top one sticks the boiler will go in to volatile lock out

 

[tamz]

Already answered with a bit more info added

 

[REDSAW]

wont shutting the flow and return valves at boiler do the same then, or is it more prone to leaking at valve after?.

 

[tamz]

More chance of a leak if you move them. Tbh i would just put an old towel down and snatch it

 

[fuzzy]

navy unions, bit of a throw back for me. working on steel, normal union are steel on steel, navy unions have a brass ring, making them sfter and therefore better sealing, happy days

 

[stevetheplumber]

just turn of the iso valves under the boiler let some presure out via the valves into a container
