Condensate Drain

pat35

Im fitting a grant boiler in garage attached to the house.There is a sink on the opposite wall to where the boiler is fitted.im going to connect up 1 1/4 abs pipe through the wall and bring it into the garage and use this as a condesate drain.I will also fit a trap on the abs pipe in the garage.
1/ Will this arrangement be ok?
2/ If the boiler is not running during the summer ,would the trap run dry and cause back smells,and would there be a better solution to this?

I don't think anyone is going to assist you on here with a diy install of a boiler that could potentially give off high CO if not installed correctly. If the condensate pipework isn't installed correctly it could also leak dangerous co fumes

Yes ,bring out the 1 1/4 pipe from the bathroom.connect 3/4 qualpex from the condensate trap at the boiler to the pipe from bathroom,making sure both ends are SEALED.

As far as I know any pex pipe isn't yet approved for condensate.
And sealing off the pipe completely is a bad idea because with no air break, there's a high risk that the condensate trap will have its water syphoned out and therefore your pipe becomes a flue for a period of time. If this pipe is a flue, and the boiler is installed by a DIYer and not commissioned, then you've a good chance there's gonna be high CO in the waste pipe

What pipe is approved?,what pipe do you use for condensate?

would the air break not be in sink

I've ever used pex for condensate
Id always use 22mm plastic waste

Yes this arrangement should be ok. Just follow the MI when installing/connecting condensate drain pipe work into 1 1/4 wastepipe. If instated properly it should not cause any siphonage from trap and finally on completion get the boiler commissioned.

No decent self respecting service engineer is going to commission a diy boiler install

How so? I'd put the air break close to the boiler if possible, depending on pipe run length

Any plastic pipe is approved,copper is not

Are u sure?
I'm not 100% sure myself. Maybe Pex is ok on a very short run but it bends too easy which could leave sagging pipe on horizontal areas and it Wouldn't be neat or straight on vertical

i dont think this is approved.if you leave an air gap and the condensate trap runs dry,are you potentially leaving a gap for co to escape, the grant vortex manual says it should be sealed to an internal waste

Could be a bit tricky alright but if you ask nicely and on inspection if everything is found to be ok I don't see why a service engineer wouldn't commission the boiler and fill out passport. This is assuming now that on inspection boiler is installed to MI.

True on the vortex alright. But in many gas boilers, they insist on a tundish being fitted. So each to their own I guess

In fairness no DIYer is gonna fit a boiler correctly. And no self respecting service engineer will sign off on it.

except in this case going by op previous post he is not a Diyer,more than likely a plumber

Why in God's name would you put your name to someone else's work?

Madness.

Some plumbers fit boilers and dont have a flue gas analyser or coursers done to commision or sign off the boiler to validate the warranty.it quite normal for a plumber to get a service technician to do this

Fair enough.

But in my opinion anyone who cares about their work and name or even not wanting to end up in front of a judge would be stupid to sign off on someone elses installation of a boiler.

I seriously doubt it if he's asking about a simple waste solution to a condensate pipework problem

Well when you service any boiler your putting your name to that boiler. If anything happens to that boiler in the mean time it falls back on the service engineer who serviced the boiler last whether or not a 1000 Cowboys were at the boiler previous to you.

So what's the difference if installed correctly.

Not the case,its either installed correctly or its not,and the persons commissions the boiler sets up the burner to mi .so the guy who commissions the boiler is signing off on his own work

point taken.so lets take it he is a plumber..,what advice would you give to connect a condensate waste from a Oil boiler to a internal waste?. What seems to be a "simple waste solution to a condensate pipework",doesnt seem so simple after all,and if op is competent we should be adviseing him correctly..

In the event of a incident the commissioning engineer doesn't get to choose which bit is their responsibility and which bit is the installers, they have Duty Of Care and the level of responsibility is decided for them.

When you sign off on somebody else's work there is a level of risk for any issues that may arise irrespective of who's work it is. I don't put my name to other people's work as I have trust issues.

As a manufacturers representative I have seen many situations where it becomes a petty blame game when I identify faux pars on a installation.

Condensate lines are simple but yet mistakes are made, why take a risk by following online advice, the safe option would be to have a local tame Oftec engineer looking at the installation and giving advice.

As I said in a previous post.

"Well when you service any boiler your putting your name to that boiler and saying that the boiler is installed and running to manufacture specification. If anything happens to that boiler in the mean time it falls back on the service engineer who serviced the boiler last whether or not a 1000 Cowboys were at the boiler previous to you".

So what's the difference in commissioning and signing off this installation if installed correctly, as I am sure you don't just only service boilers that you have installed.

It's only a problem when it's a problem.

Servicing a boiler and signing off on a new installation are two completely different things in respect of responsibility as I have witnesses.
