Working with other trades

[plumb_know]

Have a job coming up where customer has converted bungalo into 2 stories and now wants all first fix put in so floor can go down. At the moment the building is a skeleton. I have never done plumbing in essentially a new build and was wondering how's best to 1st fix rad tails so they remain straight when floor is laid and walls fitted. I would normally hang rads then pipe up to them.

Would like to know how others approach this type of work to ensure everything is still in the correct positions and straight when I return to 2nd fix?

Thanks

Sounds like a job i was on where two Kosovan £20 a day meatheads plasterboarded over all my work before I'd finished.

Gaurd your work 24/7 don't let anyone near it.

Cap any open ended pipes.

On the first floor builders usually put the floors down before they board the ground floor ceiling.
I sometimes bring rad tails out of the wall if I don't know the finish off the walls, that way the floors and ceilings can be done. Make sure you centres are right and fixed well to stop the builders kicking the tails.

I try not to quote for this sort of work & just do it on hourly rate. The number of times builders have assured me that floorboards will be loose....and when I get there t&g chipboard screwed down! As above, always cap your pipework & pressure test - make sure builder witnesses pressure test. If walls aren't plastered when you bring tails up through floor, then let builder know that tails might not be 100% vertical.

if its quality work i use munsen rings to hold pipework in place then screw the studding out just means decorator has to fill

Notched joists and straight lengths of pipework before flooring. Then tails and pipework through studwork once flooring and studwork in place. Plasterboard to ceiling will have to wait. Never trust a chippy, if pipes don't rotate after flooring they're probably nailed.

theres a few ways to do it depending on whats happening, sounds like I would want to get all rad pipes to where the rads are going and speak with the chippy to make sure he leaves traps in them locations , then hang and pipe the rads at a later date once all the walls are ready even if you need to remove the rads for decorating just make sure both valves are capped off..

Whichever way you go with always pressure test and leave pipe work pressurised
If any one puts a nail through a pipe with 8/10 bar in, they wont be able to keep it secret
The above saved me a lot of bother a couple yrs ago, left a new build 1st fixed and pressurised to around 10 bar and when the scroats tried to cut the plastic to take the copper tails, they got a soaking and pressumed it was all live so left it
All I had to replace was a short length of 22mm hep and a 90

Thanks for your advice everyone, I will leave it pressurised and let the customer see it once leaving site from 1st fix. I will see if chippy will leave access to rad areas other wise I will have to use plastic coming out of walls centre to rad like in most new builds I guess.

If I was to use Munson rings I guess I would need to confirm with builders finished thickness of walls when plastered as wouldn't leave any room for error? Don't want wonky tap tails

Appreciate all the advise

Sorry Steve misread message so you use Munson ring above floor level to stud then chippy cuts groove out where tails are? Have I understood that right?

Thanks
