Converting to combi pipework

[Razor900]

However, lacks the professionalism to enter a discussion without being offensive to other forum members.

Perhaps you could consider the word twaddle as offensive........

I would have said ****wit personally especially as the OP had already said he didn't want to explore that concept

Rather sad if you have to look at that sort of personal criticism to create a strawman as your argument is non existent

That concept was not being discussed, the thread had moved on from it. What was under discussion was the water feeds to toilet cisterns. Bernard made the valid points that if the tank were taken out and the tank fed the toilets, the feed would need to be replumbed to a CW feed and likely the fill valves replaced or adjusted. Ian, whilst agreeing that the valves might require adjustment, wrongly asserted that nothing would need to be changed on the pipework and took the opportunity to insult Bernard.

No actually @muggles had already covered it.

Seems Ian was intelligent enough to realise that.....

@muggles had made some mention of low pressure pipework, Bernard had gone into little more detail and there is always the possibility that the two responses were posted unseen by the other poster - still not a valid reason for name calling in my book, even if it covered identical ground.

And the new orifice is usually already attached to the original float arm....

and is there a new washer to replace the one that has been moulded by the low pressure orifice and might no seal fully to the high pressure orifice.

The alternative orifice is supplied for use at installation to match the valve to the supply pressure.

Interesting Bernard.

Would you care to enumerate how many times you personally have found this to be a problem or is that just another straw man?

A diaphragm washer is a consumable item, if it drips you replace it whichever system you are using.

In my experience there are far more problems with shower valves when changing to a high pressure system than any other fitting.

From memory at least three ( friends and neighbours ) in recent years.

A diaphragm washer is a consumable item

which might have to be changed when the system becomes high ( mains ) pressure. If the oricie is changed then the washer is likely to need to be changed,

In my experience there are far more problems with shower valves

hopefully the OP's plumber has made him aware of this possibility and given him a price for modifying / replacing the shower valves.

Why do you want hot water? Can’t you ask the neighbours if you can have a bucket full when you wash the car or kids.
Keep a low pressure installation and see how frustrated you become when running a tap.
Someone should give Bernie the bolt once and for all.
I cringe at some posts he writes. A plumber he is not.

 

[bernardgreen]

A plumber he is not.

I have never claimed to be a plumber, but I have sucessfully carried out the the design and installation of all the plumbing in two houses.

About the same frustration as they have with the existing low pressure system. Then there is the frustration when the G3 registered plumber charges for the annual insection of the high pressure systems safety devices. Or the call out charges when one of the devices goes faulty and only a G3 plumber can legally attempt to fix the system.

Well said - I think a lot of the criticism I am seeing in this forum is based on commercial reasons for being critical. Much more money to be made over the years in a combi system than an open- vented system, much more money to be made from high pressure systems by the 'professionals', than a low pressure system.

A sad reflection on the industry if the ""professional"" posters on this forum were typical examples of tradespeople in the industry.

What, everyone of them? And only this forum?

The only unprofessional posters I have seen in this post are you and your wee lapdog

 

[bernardgreen]

And only this forum?

Some other forums have similar clashes. Some do not and ideas are discussed by professionals and amateurs alike. The difference being the polite forums are mostly membership by invitation and may involve an annual subscription.

 

[Harry Bloomfield]

If that refers to me, I am no one lapdog I can absolutely assure you. If I think someone is wrong, even very wrong, I will say so, but will try hard not to cause any offence whilst explaining they are wrong. I do not know Bernard, I have no special allegiance to him, but I do know he is as entitled to his opinion as anyone else and even if it is wrong.

This is a DIY forum, for those seeking help with DIY issues. I would describe myself as much more of a professional in some technical spheres, than a DIY'er.
