Thanks Tom, the water appeared in rivulets down the wall underneath from the back of the boiler, apparently across the whole width. Presumably it was spraying out backwards. :?

Am I correct in thinking that this has even got the experts baffled? :shock:

Hi again guys. When refilling the CH system having added inhibitor, I 'inadvertantly' allowed the system to overpressure, and the gauge went to full scale. Instead of the PRV opening, water leaked from somewhere at the back of the boiler cascading down the wall. The PRV discharge pipe is...

Sorry, it is an Ideal Isar, which has a condensate trap, it is a few years old, which has been repositioned during a kitchen refurbish. It has been overhauled by a Gas safe engineer and runs OK, but I am fitting the kitchen and have to complete the 22mm condensate pipe run. There is also a...

I was following this advice from Worcester Bosch above: connecting into the internal discharge branch (e.g. sink waste or washing machine) with an external termination, the condensate discharge pipe should have a minimum diameter of 22 mm with no length restriction and should incorporate...

Yes I want to put it into the sink waste as in my post above, in order to avoid freezing.

Thanks for all that guys. So I intend to do as I suggested in my OP, and drop it into the sink waste after the trap, using some sort of reducer. Since the problems last winter of many externally led condensate pipes freezing, is there any chance that manufacturers have/will come up with a...

I read differing views on this. Is it permissible to drain condensate into the sink waste outlet pipe? Also what connector do I require to drop the 22mm pie into the 1½" outlet pipe? TIA

Hi guys, I am about to fit a water softener, Harveys block salt type, in my son's house. He has an Isar combi boiler. (I am only using the soft water to supply the hot water, not the CH heater. This has been approved by Ideal technical.). Due to the physical limitations of the cupboard in...

That is my problem Hugh, I don't think it is PVCu, it is the orange underground drainage pipe, make unknown, and is presumably why I was told that I shouldn't use solvent weld to join them. :?

Thanks very much Hugh, when you say my original idea, do you mean using silicone or WHY to fix the boss pipe to the drainage pipe?

Perhaps I could use this straight into the underground vertical pipe, http://www.toolstation.com/shop/Plumbing/Pan+Connectors/d20/sd2887 and then strap a boss connector onto the pan connector for the sink waste. Would this be acceptable practise?

Unfortunately, I don't know what make the pipe is. :?

Unfortunately I've just found this link, suggesting I can't use solvent weld. http://www.diydoctor.org.uk/forums/viewtopic.php?p=60372&sid=1aa5f83faaae5e1a191c2f599ec3db8e However, I find it hard to believe that there is no form of adhesive that is acceptable to connect these two pipes.

I have an underground (red in colour) soil pipe rising in a concreted ground floor toilet space to which I wish to connect the toilet, with provision for a sink waste as low as possible at the same outlet. It has been suggested that the short, grey, boss pipe that I proposed to use, to allow...

I would like not to have the DHW plate heat exchanger scale up again.

No, if you note, the paragraph, (copied from the installation instructions) is headed, Domestic Hot Water. :?: :?: :?: I shall call Ideal tomorrow. Thanks guys.

I'm sorry, I don't follow you. We had a Combimate as mentioned, but would like to fit a proper softener, however this would appear to be taboo according to these instructions, hence my two questions. Thanks

I have had to descale the DHW heat exchanger on my son's boiler, and decided that it may be better to fit a water softener than rely on a Combimate, however I note this in the Installation Instructions:- Domestic Hot Water In hard water areas where main water can exceed 200ppm Total Hardness...

I propose laying a new floor in a 1890 terraced house built on clay. Due to the limited foundation depth, I would like to keep the new floor thickness to 350mm. Is there any problem with the following make-up. 150mm well compacted level scalpings, blinding sand and 1200DPM, 100mm insulation...
