Supporting pipes under floorboards + insulation

[Last Plumber]

The job is best done from under the floor otherwise you'll be moving furniture as well as lifting floorboards and carpets everywhere. If you go under, you can have it done.

If it's plastic I'll have to do it every 300 mm. It seems there's no other way round screwing something every 300 mm whatever support method I choose.

That's one of the reasons Copper is better.

but much bigger and wider to accomodate insulated pipes. You screw slide it 3, 5, 10 metres long below the joists, perpendicular to them, screw it in a few places to hold it then slide all your pipes into it.

Yes, I may consider copper then despite the price, if I can finish the job sooner.

Use some 100 x 25mm trunking then elec fact should have that

How new to this are you if you don't mind me asking? Is it just the going under that bothers you or the whole thing?

 

[kasser]

Use mlcp then

what's that?

So expensive. I'd better go under then!

I'm fairly new, thus why I've never encountered a fairly common situation like this before. But I usually encounter situations where I get to run pipes within the first floor. This one is full central heating for a bungalow. About 16 rads. I'm just trying to find a way to run, insulate and clip all these pipes under the floor boards quickly. It's a shame that I may end up using copper out of sight when I could run plastic instead.

Pipes run in the loft means a lot of exposed pipework when dropping down, not as neat as pipes coming up through the floor.

There's no furniture or flooring anywhere in the house. Full access everywhere.

How big are the joists depth ?

 

[Last Plumber]

Well if you prefer, why not go under with a battery drill and screw plastic stand off (wrap over) clips to the underside of each joist and use the plastic push fit stuff?
I personally don't like it but I am old fashioned and like you say, no-one will see it.

Apart from the next Plumber of course!

Have you sorted all your pipe sizing for the circuit?

Probably quicker than speedfit with all that 300mm clipping business

It is a shame, but copper was out long before plastic, and see loads in lofts in the properties I work in, it’s all they used. You need to weigh up the difference, I’m sure there’s not much in it and you’ll be fitting copper - welcome to OldSkool
