I'm having a new extention built which will include an ensuite and a new combination boiler.
我注意到，建造者使用塑料管道连接一些铜管，使用推接连接器，也有一些塑料管道嵌入到砖中，将用于散热器。现在这种做法普遍吗?在我那个年代，全是铜管。这些蒲松能承受水压吗?

Any advise appreciated?

我的组合锅炉一直在快速地咔嚓咔嚓地响，显然问题出在热交换器上。锅炉仍在工作，有效地加热散热器和水。我曾被一个水管工建议，需要一个电力冲洗，报价很贵。另一位管道工建议改用Ferroquest。非常感谢，您的建议将不胜感激。

I have a new shower to be installed, plus I'm re-tiling the en-suite room.
What's the best order to do this?
Obviously I remove all tiles and shower fittings first -
Then should I tiles the wall first? If so, is it best to mark the position of the new shower unit and tile to overlap, still leaving an area of plastered wall behind the shower, or should I tile everywhere and mount the shower over the tiles?
Or should I install the shower first, and then tile up to and around the shower?

18Oct - Whilse in an ideal world I kinda agree with Kelly plumbing and others, and while it would be great to spend a few hundred quid on a plumber (times "x" for the number of jobs), some of us don't have that kind of money to spare right now!
Thanks to London Lofts for actually answering the question, guys! That is exactly what I wanted to know.
Be assured, I look to the professionals when I'm out of my depth, but then that's why these question forums are here?! If you've never done it before, then how do you know?

18Oct - Just realised that London Lofts answered the question relating to the shower tray, but it's the wall shower itself that I was speciifically asking for?
这是一个协调问题，真的——如果我请了一个水管工来安装淋浴器，我是应该把瓷砖留到安装后再铺呢，还是应该先把整面墙都铺上瓷砖，或者我应该在淋浴器的位置做个标记，然后在瓷砖上留个空隙呢?

there are no nut fittings, just two plastic type hooks where the seat clips onto. so assume the screw part is within the pan. What to do?
The toilet is fiited into a cabinet,and to remove pan would have to break all the mastic.it looks like a fitted kitchen.
Only the lid of the seat has been broken, but will need to fit complete new unit.

Toilet make/model is an Ideal Standard close coupled WC.

The flush generally continues after either the full or half flush buttons have been pressed, then continues to dribble very lightly until the next flush.

偶尔会停球，但在下一次冲球后会再次运球。

The WC seems to have been discontinued, but fitting instructions for a similar model can be found at http://www.ideal-standard.co.uk/InstallationInstructions/4230%20close%20coupled%20wc.pdf

我是一名紧急管道工，已经干了18年。

几周前，A从一个网站上得到了一条线索。顾客原来住在普雷斯顿。我住在曼彻斯特，一小时车程。他有一个漏水的水龙头。

I advised that I could fit him a tap reviver kit to his tap and also a new ball valve rather than repairing the existing one. I quoted him (over the phone) £96, which he said was too expensive. He asked if I could do it for £50 and I agreed to meet him in the middle (ish) at £75. He was happy with this and said it was reasonable as I promised I'd be with him within 90 minutes and I'd guarantee the work etc.

When I arrived, the customer and his wife were friendly, very chatty and with a load of model trains hung in cabinets on his walls, we found a mutual interest, which we chatted about. I replaced the ball valve and fitted his tap reviver kit, checked everything was ok and they were over the moon. Happy to the point the customer's wife kissed me as a left. I then got a text a day later saying how happy they were with the work, how friendly I was and what a nice guy I was etc, and would there be any way of them leaving me a review online. I sent over a link for them to leave the review and received a 4 and half star rating from them. In the comments section, they put how good I was, how friendly I was, how efficient etc etc, and the last line said (words to the effect of) 'the company is good if a little expensive'

Fair enough I thought. All my other reviews are 5 stars across the board and with really great comments that I'm extremely proud of - I see a good review as a reward for the effort we have to put in to make customers happy. I stupidly (really stupidly!) decided I'd comment back to the review, and publicly explained why I'd charged £75 for the job. I explained that by the time I'd bought a new ball valve, a tap reviver kit, spent £25 on fuel and spent an hour each way travelling, that I'd only actually made £30 on the job. I was on site for nearly 2 hours, but most of that was chatting about trains and diabetes (something we both have in common!). It felt like I was visiting a friend and doing them a favour at the same time.

After my response to the review, I heard nothing until today, when I received a review from the same customer on another website giving me one star and saying how although I'm an average plumber, I represent 'rip off britain' in person and by charging £25 for fuel I'm a con man and will never be asked back to their house. I called the customer to sort it out and he told me I am a rip off merchant, he felt I'd taken advantage of him and when I offered him his money back he said it was an admission of guilt and then hung up on me, refusing the refund.

I'm wondering if I'm looking at it all wrong?

Is £75 for a ball valve and a tap reviver kit too much? Is it me who's in the wrong or the customer?

Your thoughts and comments would be greatly appreciated!

My toilet bowl has an excess build up of limescale and as such doesn't always flush away and tends to get blocked, is there anything of industrial strength to use to clear it or would I be best off having a new toilet bowl fitted, and can this be done on it's own as there is no problem with the cistern.
