Derek in this video takes a look at the correct methods for installing a condensate drain on a gas boiler. Checking and making sure the drain is correct could reduce the risk of boiler breakdowns this winter.
Boiler manufacturers have had long enough to sort these issues out👎 Always the installer having to add more costs onto a never ending quote. Like Viessmans idea 👌 Think if Worcester still making the condensate sure that would be my option👌Again another nice video Derek. Cheers keep them coming.
Hi does rain water get into the outlet of the flue and where does it go? Does it travel through the flue and out the condenstate pipe, I’ve had a new boiler fitted with a deflection kit on the flue the boiler is a ideal logic max. The deflection kit slightly angled upwards towards the sky and the instructions says it should be like that, but I think it would be catching the rain?
Does condensate erode the glue used in ancient (1992) plastic pipe joints? I had a condensing boiler fitted about 12 months ago, with the condensate pipe plumbed into the waste pipe from the kitchen sink, just before it enters the wall. I've noticed that vertical run of the 40mm waste pipe outside of the house is often damp below the glued joint with a 90 degree bend where it exits from the wall. Never happened before, and that joint has been there 30 years so the only (unlikely) explanation I can think of is condensate leaking through through the joint. Has anyone else seen this?
Had a new ideal vogue boiler installed 2 weeks by ideal accredited Max installers adding another 2 years to the warranty. They didn’t upgrade the existing outside condensate pipe to the drain to the new size, as per regulations.
Thats interesting....but when I was trained on discharging internally....no air gap what so ever was allowed internally...as our "British Gas" trainer showed us by blocking the flue the condense pipe started to spew product's of combustion?....this was 15yrs or so ago...I also terminated into a internal stack or after a trap or made sure the trap end was sealed ???...please advise is there new safety features to shut boilers down to stop this happening....???from memory it was a Valient....🙏 😊 also condense pipe was always to be treated as part of the flue ? Has this changed to?
I'm catching the water in a jar because had new kitchen worktop installed didn't want to drill hole for it .empty everyday when boiler kicks in sometimes forget 😂 need help and this video really helped.thanks
Hi Derek. A very helpful video from you about the regulations regarding condensate pipe, I have learned a lot from you. A question please if I may. My wife says she doesn't want a length of pipe with black insulation showing, painted or not, running across the full length of our new extension. So, would it be okay for me to run the pipework with insulation on, through the inside of a length of drainpipe from the house to the nearest drain? Just to let it look more in keeping with the rest of the build. Thank you. And all the best for 2024.
One thing to check when connecting condensate pipe to internal waste/soil pipes is the property sewage disposal system. Mains sewage treatment no problem. But if there is a small sewage plant or a septic boiler condensate will lill it dead. In these circumstances connevtion to a soal away or raineater pipework is essential!
it is BULLSHIT. i licked condensate from boiler ad it is only tiny bit acidic. Not like everybody is writing. I guess it all depends how efficient your boiler is and how much CO it emits. And what flow temp you running. Known that in uk everything is old and inefficient i guess that's the problem. But when you run your boiler at MAX 45c flow temp you have no problems because condensate is so weak in acid that everyday soap, fairy, dish washing liquids\tablets and also washing machine chemicals they all are very strong bases so it neutralizes acid.
Going off topic a little here though your expertise would be appreciated.....if a ECV is falling to the on position & it's not possible to replace/move handle via removing pin & repositioning, is that situation classed as AR & reportable to the ESP
I've been using a Worcester CondenseSure Siphon for years. It dumps into the same stand-pipe as my washing machine, then into an external drain. Never had any problems with freezing
Not a good practice. If both appliances operate at the same time you run the risk of contaminating the trap as condensate could back up into the boiler. Also washing machine upstand is designed for the machine only. Each to there own 🙄🤷♂️
No there isn't a choice with the Manufactures 1:45 or Building Regs 1:55. Building Regulations are statutory manufacturers' guides are not statutory so must comply with Building Regulations. Can copper condensate pipes be used internally?
Internal is good, but you still have to trace how that pipework continues downstream? I've seen Bath waste freeze up. Bath Used mainly as a shower so slowly draining. So condensate same. Also used a product called "condensulate " in the past, not sure if it's still available? Keep up the good work.
I always use 40mm waste pipe and have never had one freeze , seen plenty of commerical boilers on 40mm pipe have no problems. Myself 32mm and lagging it is a bit of overkill
Last week I was installing a boiler and run 32 mm pipe external. Then lagged with the correct lagging. Not the grey crap. Anyway two British Gas engineers asked why I lagged pipe as they fit 40 mm and said you then don’t require lagging. So all those lovely overpriced b g. Installs they have done are wrong. Or are they correct. ?
