You only need foul ( solids / food waste ) having line of sight of the inspection chamber, and having clear running ( other bathing / waste ) water branching in ( with Y branches ) is perfectly acceptable.

Yup. Relegated to the "cock-womble" shelf. I would say a "moron", but don't wish to fall onto my own sword lol. At least I can't hang myself......as I've just been to the rope shop and it's just all recently been snapped up by someone.

I can’t remember who does the one I was discussing, but I can find out 👍. I discuss a LOT of stuff each week, and just the one brain lol, sorry 😵‍💫

Congrats!! Most of the help, support and advice you'll need is either already written here, or can be discussed as and when. Please do not worry about adding to older threads, as it's good to blow the dust off things. All the best of luck for the journey ahead. Ask first, then jump , but, so far, so good.

There are 3ph diversion controllers available. I looked at one for my current 2 projects, where there is / is going to be 3ph on site with sizeable PV systems installed.

I dealt with Ryan at their head office, after some installer issues, and he was exceptional in his actions / support / resolve. I cannot speak highly enough of them.

That is Dovista?

You self built ( in the truest meaning though ). Doubtful that it would be the same for anyone who can’t physically build it themselves or are in the trade with good contacts / knowledge etc.

The perfect solution to the OP's issue? The job's yours . Let me show you to your office.

Good lad. We will not, of course, accept your word for it. Please post photos here for "authentication". We will make allowances for it being cold when we score you. Don't forget to insulate them. You never know when you'll need to add "air con" ( not cooling ) from an A2W HP

Yup. It's quite a simple process to test, just a little tedious when you're balancing as you need to keep going around, and back on yourself, as altering one valve then affects the others. I just looked for a ventilation ( strategic ) partner who was PH certified, as some of the others are not, and for good reason.

Google 'delta T', and get a reality check on where the dew-point would be. I'm not sure what books you've been reading and researching from, but I'd avoid the fiction section from now on.

As you have technically not yet broken any of the rules of this forum, we can't really ban you. Plus, have you ever heard the phrase "give them enough rope"? Also, this is just pure gold, keep them coming. 😆 I've not laughed this much since Auntie Mabel caught her left tit in the mangle. @Kelvin Could I please refer you to the T's & C's, section 69, item 69, subsection 6-9, where it clearly states "thou shalthst ( spelt correctly, I checked ) not engage-eth in the medieval act of the browning of the nose". This is a grandfather clause, often overlooked, so if you wish to avoid a permanent ban from Buildhub I urge to to take all of today, and 37.4592% of Sunday ( not this Sunday, but the one after next, and I'll be checking ) to properly familiarise yourself with our policies. I expected better of you tbh. 🙄

Not that I care to waste any of my valuable personal time responding to such a nonsense response, but what exactly do you consider "rude". I asked you two very simple questions, and, if you want help, maybe you should read between the lines and answer them so you can receive said help. Folk on here reply to help people for free, on a forum which is free to join, so, IF you wish to jump down, momentarily, off the highest horse I've seen for quite some time, I would be happy to answer you questions. For definition; A "moron" would install a system which was not properly designed and installed as fit for purpose, so if I was the kind of person to make any assumptions or be "rude" to you, my question in my first reply would have read "What MORON designed this system where they didn't define the parameters or install it fit for purpose?", and then, referring to someone as a moron would be fine and appropriate. 👍 For further clarity, I am NOT referring to you as the moron, yet, as I do not know if you were said moron or not. Once I have ascertained who the moron actually is, then I will engage, with all of my many years of dealing with morons, my retort. Usage of Moron The terms idiot, imbecile, moron, and their derivatives were formerly used as technical descriptors in medical, educational, and regulatory contexts. These uses were broadly rejected by the close of the 20th century and are now considered offensive. As we like to offer comprehensive replies here at Buildhub, please be aware that, rather embarrassingly, your attempt to insult me is actually about a century out of date. You may need to go to another forum to get some up to date material. OK, so lets assume you did come here fore free help, I will rephrase my questions to you as follows. Should have read; Please could you tell me if the already installed ductwork has been insulated? Are you aware that there is a huge difference between air con and cooling? There you go, and hopefully this makes up for me upsetting you so much by trying to help you, for free, in my spare time. Please also be aware, that If you can't get a reasonably speedy and satisfactory answer here, then please go and employ a system designer, who will take money from you in return for the answers you seek. Kind regards, Nick.

To read the above replies, lol. You won’t get answers that carry any weight on any forum, and if someone does answer you then you can’t use what they say anyways, so you’re just wasting your time, sorry. Go ask your BCO or employ a drainage engineer. Simples. You will need to part with some money to get what you need, that’s not going to change.

I know when I’ve drunk enough beer, sir, as my shirt gets warm ( from me dribbling onto myself in my sleep ) 👍

This is a wheel which does not need to be re-invented! is present in a badly designed and executed installation. Zero or near-zero audibility on my installs is a No.1 priority.

Nobody can answer this other than the local water authority, and your intended building control person(s). I know they'll say 160mm, but I can't tell you that, as what anyone says here is an educated opinion, but just that, an opinion. Go ask the relevant bodies whom will reside over the correct / final specification of this project, as the installed systems will need to meet or exceed their standard to be signed off for your completion certificate.

They'll just tell you not to do it. They want a simple life.

Have you insulated the ductwork supplying air to the rooms? Do you understand the difference between air con and cooling too? Just before we get 'into it'

A Beattie PH?

Agreed, but they are looking at very different things these days.

Not had one argue the point with any of my jobs. The second you push back against a BCO they often just say "fine", unless it is a categoric blunder.

A few strategic, and very well positioned, IR panels are now sounding an option tbh.

Sacrifices have to be made. I'll have a chat with her later today. Have you been keeping up to date with your over 50's plan? So, without poking the bear with a sharp stick, are you one of the PH believers who is now reconsidering their "faith"?
