Vaillant Ecotec pro Low working gas pressure

[Last Plumber]

Agree. I have been in touch will the call centre and they wont send another engineer until I can provide proof/paper work from candent to show that gas meter pressure was checked. Thats going to take another 5days!.

If you are without heating and Hot water because of something you think may be their fault, then you could insist on a visit?

Bet he’s tested from the gas valve need to add your resistance eg normally around 2.5 mbar and 1 for your line so total 3.5 mbar

Needs to cut a test point before the gas valve on the gas pipework underneath the boiler

Is this normal for a routine 2nd service? boiler 2 years old?

Nope. I fit one when installing the boiler. As I once had 14.5 at the valve. Put a test point in before the boiler and had 19 at the boiler.

Thanks Very interesting ...

On a side note. When I requested to have the condensate trap cleaned, he put it back without filling with water. When I asked why? As Service manual says to, his reply was no need for this type of boiler, when boiler runs it will fill by it self.

Is he right?

No. The condensate trap should be filled prior to running the Boiler. If the trap is dry, products of combustion will exit the condensate pipe termination point until the trap has filled.

If all that you say is true, I think you should voice polite concern in writing (email) to the service manager.

We’re you watching, reading the book and offering an opinion during the service?

Doubt it. Bet it was all after thoughts.

Was watching, but not offering an opinion.

This thread is full of contradictions

Valliants are known to loose pressure through the gas valve ask your GSI to install a test point before the gas valve and retest , you should have 21mbar +/- 2mbar at the meter and 20 mbar +/- 2mbar so no lower than 18mbar at this test point on full load . Kop

So what I said😛😛😛

Just busting you b***s mate

 

[king of pipes]

Sorry H didn't see your post mate but great minds bud! I had the same issue on a council contract years back so now fit a test point before the gas valve saves alot of grief . Kop

When he did the annual service did the engineer also open up the burner and brushed through? Has he checked the exp. vessel, flue integrity, has done all the **** ? Seems like he either was lazy and rushed the service or he has not got a clue. As @Last Plumber has mentioned if that all is true you should perhaps write an email.

No, burner was not opened and brushed. exp, vessel was topped up.
**** was done with a print out.
does my gas pipe have a gas test point valve? have attached a photos.

There is no test point installed as far as I can see. How did he re pressurise the exp.vessel ? Did he drain the boiler ? I do not mean the flue gas analysis I mean **** which are certain things to examine, gas rate, integrity of the flue, supply of combustion air,safety controls, etc...

I am not sure, but this was ticked on the service check list.

Was it Vaillant that Serviced it?
