Only way its restricting anything is if its never been cleaned out, do you know if it has been serviced
Welcome to the forum. Although you can post in any forum, the USA forum is here in case of local regs or laws

I'm not sure, have no evidence to suggest it has or not unfortunately. Very stressful this plumbing stuff when you've a heavily pregnant wife, a two year old, no heating, and £1500 less in the bank!

I reckon if you got a third opinion and it's the same then get the original man back to sort it out.

Yep. Find plumber number 3.
Best practice is for MVC to be on return immediately before boiler, but is sometimes impossible to do, and on the flow is not wrong if only choice.
Do not pay for a PF at this stage. If it was working okay before, it wont suddenly get full of sludge. There is something silly going on, and sometimes one cannot see the wood for the trees. The plumber has to start from the basics. I was getting a headache trying to work out the pipe runs from the photos, but I would be looking at:
a/ Air Lock
b/ a valve that is closed, or partially closed. Either because it has not been opened properly or is internally damaged
c/ Does hot water work okay? If not, blockage in heat exchanger. Possible movemnet of muck in system when draining / filling.
d/ Crud entered the system when re-piping. It does happen.
Has motorised valve been checked?
Although a little irrelevant to the actual probem - Why were you chasing pipes in? How was that done - what measures were taken to prevent the plaster cracking from heat?

magna cant be blocked or shut of as the op has hot water the magna is where it is as theres no way to fit it adacent to boiler as pipework is to close to ceiling and any magna is better than none
Sounds like air to me.
If you've replaced all the rads and the system already had a magna clean fitted you probably don't need the system flushed.
The boiler is more than capable of dealing with the bigger radiators.
Given the pipework lay out its more than likely air in the system you have no air vents fitted which will make it harder to remove but not impossible. any decent gas fitter should have that up and running quite quick.
also advise checking your valves on the boiler, magna clean filter and rtn pipe from cylinder are all fully open. Also there is a small water sample point on the boiler, opening this into a bucket to remove any air might also be worth considering.

We had a super heating engineer from Shefford work on our property, came highly recommended by neighbours, always the best way imho, pm me for his details if you like. I warn you though he is very busy, like all great HE in my experience.
Am I right in thinking that under the latest regs only Competent Persons in other words Benchmark Members can work on central heating, either gas or electric, as it is now notifiable to building controls?

Anyone can do anything in the uk tbh, but you must be competent in the eyes of the law to touch anything really, you can prove competency in gas and electrical installation/work by being a member of a competent persons scheme in theory.
any body can do plumbing and heating works, it's only when it goes wrong most people and companies question competence

Not quite as simple as you make it sound. A quick google produced this from gov.uk

Some surprising additions now just be notified, such as a new flat roof covering. Imho it's always best to notify, especially if you are planning on selling the property or need to make an insurance claim.

You think? Don't forget the major changes to the Consumer Act last October! I reckon about half the jobs I did between 10 and 20 years ago would need notification now. Eg new en suite, new cloakroom with EC, new bathroom lights, new HWC, new immersion heater element
This is all very well But who is going monitor it, are we going to have notification police :bobby: knocking on peoples doors and asking to inspect there homes, and what about the DIY brigade ? who monitors them ?? Just waiting for when we have to notify how much toilet paper gets used . :toilet:
I'd say that your problem is most likely
air lock or pour balancing of the system,
You wont need a power flush and i cant see why you'd be happy to pay for one but not for just the materials for the original chap
however if you've lost confidence in him then that that
I'd get another couple of experienced heating engineers round to have a look, It's most likely something simple, and i wouldnt have any alterations done or powerflush until someones played with the system balancing and such
for years and years many many jobs have been notifiable, probably a good percentage of work thats not a like for like swap has always been. What should be and what is done is a different matter.
The only trades that have any sort of policing is gas and electrical through its cps's however good you may feel this is currently done.
unless customers are willing to cover the huge cost increase in policing work done it will never change, from my experience most customers want the cheapest price and only care about such things as regulations when problems bite them.
