Megaflow Direct DD 210 System questions

[Paul Cockhill]

Hi,

This is one of my first jobs and am looking for some advice

Am installing a Megaflow system and have almost completed it, however found fitting the 22mm cold inlet pipe very difficult and could only get it in 2mm, called the Baxi engineer and he could not believe it and has ordered a new cylinder, luckily it is covered by warranty, has anyone else had a similar problem?

Also when I have installed it, what is the solution for flushing, I have been recommended Sentinal X100, would this be best or does anyone have any other ideas?

Also what is the best way of getting the flushing solution into the system

At the moment there is no way of commissoning the system as the bathroom it will be suppling is not built yet and will not be for a while. So what would be the best way of checking the system for leaks and to make sure it works? I guess I need some form of tap to be fitted onto the end of the hot water feed pipe, in order to get rid of the air?

Many thanks

Paul

If you know what you are doing then you wouldn't ask about the X100!!! This is a central heating inhibitor, you have fitted a DIRECT Cylinder? So.. there is no central heating. As for asking what is the best way to check for leaks, do the job right first time then there will be no leaks, however you could air test it.
Have you got your Unvented Cert??

If you have your Unvented cert then why are you asking about flushing with X100? also why are you asking about pressure testing? These are covered on the course so YOU should know this as you have done the course. Who have you got to check it over? If they went on the same course as you I would be worryed.

Welcome to the forum. I've never read this thread. Bloomin worrying. Proves that the day course for fitting unvented cylinders falls woefully short of the standards that are really required for fitting something that has so many potential dangers if done improperly.

Not least flooding....and at worse....a major rupture, and explosion.

Dosing with corrosion inhibitor. Madness. 2mm in the cold inlet. What was he trying to do? I reckon solder the pipe in the threaded connection. Funny if it wasn't so serious. That is in someones home....and they paid for it to be there.

He might have got flushing confused with disinfecting it.

 

[southcoastboile]

are you sure this is a direct cylinder? i think he is talking about an indirect cylinder and asking what the best inhibitor is to use on the heating side

 

[Dannypipe]

I think it is a direct cylinder and he is just a complete novice. I've just looked at his threads started. He's a training fast tracker at southampton college. In his 40's, and in the middle of a career change from travel to plumbing.

He's asked a lot of very odd questions. Including in this threads instance, how to check it for leaks. I genuinely think he thought he had to fill it up and dose it with Sentinal. I could be wrong. Either way, my point is....this guy is installing these cylinders in peoples homes. For money. By the sounds of it, without the help of a properly trained and time served plumber.

Doesn't that worry you a tiny bit?
