New designer radiators filled with iron balls

You can get a insert plug to blank it off cheers kop

or even better get a radiator manifold

Would the blank not create an airlock.

Shaun, wouldn't they be a fortune in comparison? These speedfits are a tenner each...

 

[ShaunCorbs]

yes thats the draw back

Should not be a problem bud as long as you fill and vent your system correctly and add good quality inhibitor i used hep 2o manifolds on a install recently as i did not want any fittings under the floor it was 2 flats above a shop so if there was a issue it would be disasterous i left two traps hatches in the floor where the manifolds were .

Cheers chaps, I'll have a look at the hep2o ones in that case. The new system is going in a ground floor attached garage adjacent to my hallway. So fitting all the central pipework into the hall under that floor which will only ever be laminate. Then drilling through into the garage which is a foot lower on floor level.... I had thought about hatches as wanted to fit polished porcelain... But there are other connections I'll always need access to. Including in wall connections dropping down to elbows and 10mm to 15mm where I've fitted up the wall into a central placed box (behind rads).

Actually on reflection, I've used speedfit everywhere and have spare pipe to use.... Presume it's best not to mix n match?

Nothing wrong with speedfit bud been around along time its just a bit stiff and can easily kink if you are not carefull i will post a few pictures of how i did it with no joins in the the walls at all to the rads may help you out cheers kop

Nice looking job there mate, very neat.

I much prefer speedfit, although did get the sample Hep stuff and was quite impressed. I'm just not so sure you can use SF on Hep connections?

I became impressed with JG Speedfit after using a 15mm elbow as a pushfit connection on my pressure testing pump. It has been connected and disconnected hundreds of times over the last few years, to every brand of pipe that it would fit on to and it still holds pressure just fine. I can't believe how reliable the thing has been! I use copper for everything I can but if not possible I trust Speedfit and use that.

 

[1animal1]

That's very reassuring.... Would you trust speedfit pipe on hep2 manifolds though?

The speedfit is very easy to use and haven't had one fail yet. I do generally try and use copper with them though unless on a big run.... Much prefer not using the seals where possible

It's one of those situations where I would use it on my own house because I am confident they are compatible because the outside diameter of both brands will be made to a British Standard.

In a customer's property I would avoid mixing brands in case something went wrong and I was blamed for it because I mixed fittings from different manufactures. It would likely invalidate any warranties on the parts I mixed up.
