Replacing stopcock, which size

[ShaunCorbs]

Yes both the same the only thing that isn't on there is a check valve Normally fitted between the cylinder and bronze pump

And that's fine just can't use plastic pipe

Make sure it's well insulated

No probs... Is it worth bothering do you think, would the hot water coming through be that noticeable in a house this size? I'm fine adding the pipework but given the cost of the pump and added complexity.

The runs are mostly in the insulated garage. I've used the thickest foam I can get away with for the 22. Going to have to source some thinner for the 15mm due to my brackets restricting.

Quite involving this plumbing lark! Been at it all day trying to do as much as possible, getting access, laying pipes etc before having to turn the mains off and drain the Ch. 600mm to get through the garage wall! Massive pita

 

[ShaunCorbs]

That's upto you tbh

And it would of been easier on you if you had a plumber (who is gas safe and G3 registered) helping you 😀

 

[1animal1]

It definitely would. Only reason I haven't is, my trusted chap is always so busy, I'm always conscious of this so try not to trouble him unless I absolutely need to 🙂

Plus I enjoy it... There's a challenge around every corner! 😀

Morning chaps - Success! I have managed to replace the cold water main, hot next followed by the CH repiping.

Question - As I will be looking at a complete new system in Jan-April time - firstly, do new boilers tend to have their own magnetic and solid filtration?

My thinking at the moment is this - to fit either a second hand Magna to the 22mm pipework to cleanse the system prior to the new one being fitted.

The dilemma is, do i spend £40 on one of the few second hand ones on ebay as a make doo (best option if new boiler comes with one) or go and buy a new 22mm Magna, or perhaps the Magna pro 2 if it's worth the extra? assuming it will get used on the new system.

Thoughts please 🙂

 

[ShaunCorbs]

No they don't

Best option is both but not second hand

Adey pro 2 would be the best one

 

[1animal1]

Thanks Shaun! much appreciated as always.

Gathering the Adey 2 is worth the extra, what's the difference? - do they lose their effectiveness with age? and whats the service/shelf life of them?

 

[ShaunCorbs]

Yes just overall better design

 

[1animal1]

Any view on other brands like Trappex?

 

[ShaunCorbs]

Cheap and nasty

Either adey or spirotech

 

[1animal1]

I was just looking for best price and stumbled upon a thread from years ago....

Seems best I can see atm is £82 - amazing how some places are wanting £120 for the same item!

This won't be fitted optimally for the moment - I can't get it near the current boiler so it will be on the ground floor pipework - current system being upstairs fed - gather any crap from upstairs will always work its way downstairs with gravity and be swallowed up in this...

 

[1animal1]

is this the Spirotech equiv? They look very well made!

Spirotrap MB3 Dirt Separator 22mm *Special Offers*

or this which i presume is the same but with air remover...

Spirocombi Horizontal Air & Dirt Separator Brass 22mm

 

[ShaunCorbs]

Yea that's made by them

 

[1animal1]

How do they work in comparison to the Magnaclean's - they don't seem to be magnet based, perhaps swirl pot style filter?

External magnet

Black shroud

Thanks Shaun...

Last question on this - which would you fit on your own system?

Adey pro 2
Spirotrap
Spirocombi

 

[ShaunCorbs]

Adey pro 2

But there all about the same

 

[1animal1]

Update... I only had one option I could go for given its first location will be beneath the floor, and the flow on the return will be coming in from the top assuming the Adey or spirocombi due to them having to be upright . So I went with the MB3 separator in the end... Spoke with Spirotech prior to ordering for confidence in the filter material and the getting the right option. I had gone to them with the idea to buy the spirocombi sludge and air remover, but the flow wasn't in the right direction for my situation and the lady kindly pointed out that it wouldn't work optimally anyway... As a proper industrial set up by comparison would have the sludge remover on the return and the air remover on the flow... so I've managed to get the MB3 and RV2 for the price of the combi model @£115.... One place had this package, the rest all wanted close to £150 for both! Job well done I think...

Don't make me cry with a decent trade cost please 😀

Where from?

 

[1animal1]

Company called Viessmann Direct... Found it purely by chance. Even the eBay specials wanted £65 for the MB3's... The RV's were even more everywhere I looked
