Changing and teeing into Flow & return pipe

[doitall]

There's a lot of reasons it may not be as you/we say, the pump could be on the return for example.

Pictures or an as fitted drawing, or you need to trust the plumber on-site, not everyone is a cowboy, even if there is a load of greenhorns in town.

Cheers Do It all. I'll get some piccys and stuff this eve.

I do understand that not everyone is a cowboy but the issues I had with the guys who installed this led me to believe that they weren't completely competent. Unfortunately I had no choice in who to use as it was handled by the company we were buying the house off.

Most plumbers i now speak to just advise me that i should rip the system out and install a combi which we can't really afford all the hassle and money. This is why I'm trying to get a better understanding of the system to stop me being fobbed off.

Think i need to find myself an oldschool plumber who isnt scared of open vented systems.

That is another problem with modern heating guys, they only know how to chuck a combi on the wall and run.

Saying that in the right place they are brilliant.

if combi's hadn't been invented half the RGI's would be out of work

As promised.

I hope it makes sense this is all situated up in the loft.

Now from what i can see the pump (which is by the boiler on the ground floor) is on the flow pipe directly after the boiler. However if I'm wrong and its on the return would that be ok?

If it is on the flow is this what could be causing me to get loads of air in the system?

Pump is with the boiler on ground floor on what i see being the flow pipe.

looks wrong to me

Pump should be on the flow before the motorised valves but after the cold fEed and. there should be a bypass after the pump and before the M V's too

It is if the pump is on the flow.

I think there is a by-pass if you look closely, not sure about a valve though.

Hi all sorry for the delay on this . from what I can see the pump is on the flow. I come to this conclusion as it's the pipe that heats up first. I'm not sure the picture will prove anything unless you know which pipe is flow and which is return on an alpha cd24r boiler.
