Boiler still dropping pressure despite new pressure relief valve

[JRP1414]

Hi,

I'm looking for a bit of advice if I may please.

I have a Ferroli F30E combi boiler. It was already in the house when we moved in so I'm not sure how old it is, but I would say at least 5 years old.

Over the past 12 months, I have had to top up the water a couple of times as the pressure has dropped below the minimum 1 bar required and the system has shut itself off. I assumed that it was normal for this to happen over time, not really knowing much about boilers.

A couple of days ago, the pressure dropped again. I refilled the system but within a few minutes it was gone again. I followed advice given to other users on here and checked the pressure relief valve outlet outside. Sure enough, the water was literally flowing out.

I called a gas engineer out who confirmed my thoughts that the PRV had failed. Unfortunately, however, the PRV on this type of boiler comes as a unit with the manifold and pressure switch together, at some ridiculous cost of £75-100. As a result, the engineer suggested a cheaper way around by fitting a new bog standard PRV (£15) on the discharge pipe from the old one.

The boiler filled back up and everything seemed to be fine. However, a few hours later, I've noticed that the pressure has dropped again. Not completely, but about 0.5 bar. The discharge pipe is slowly dripping outside and the pressure continues to gradually decrease.

Can anyone offer any suggestions please?

Could the new PRV be faulty?

Could this way of fitting an extra PRV after the faulty one be causing a problem?

Any suggestions would be gratefully received!

He cured the symptom. Not the problem. Few thoughts...

1. Did he just cap off the old discharge?
2. Did he check the obvious?
3. It's a ferroli.
4. It's a ferroli.......

And finally......

hang on John this thread is still open so....

 

[bigman]

Just to add it is a Ferroli they are not made in a factory like other boilers they are forged in the bowels of hell by satan himself. Can anyone guess what boilers I was working on today?

 

[kris]

Ferrolis are usually a 10 on the richter scale

Gloworm?

Harcal 430?

 

[happyflyer]

Hoval flame reversal ???? Hell guys are there any boilers that you think are any good, there must be one at least.

 

[happyflyer]

Harcal 430?

Now Ermi,

What was wrong with the Harcal 430 down firing pressure jet, I must have fitted at least 200 of the things.

 

[TBServices]

Just get rid of the Ferroli otherwise you will live to regret it.

Nothing much! ------ nothing much right either.

 

[Crinkmeister]

My opinion: - you tried the low cost repair option - unfortunately, it didn't work. So I think you have to get your GSR back and ask him to fit the proper part.

On the plus side, you can sell him an as-new PRV for only £14.99 (that maybe doesn't work properly?)!

Still a few around after 40 odd years so cant be too bad

 

[JRP1414]

Well it's fixed. Seems the pressure gauge was a bit out so it was over pressurised. Looks like the cheap fix worked.

Thank you all for your fantastic advice, it was really helpful.

I shall rest assured that if I ever need a gas man in the future, I'll know exactly where to come.

Your mates have done that one to death. Got any new material?

 

[Dotty]

Yeah. How about watch your lip.

That material new enough?

Don't get snotty with us just because you have one of the worst boilers on the planet.

 

[Ermintrude]

And you were playing with boiler?

 

[JRP1414]

Yeah. How about watch your lip.

That material new enough?

Ooh, what rattled your cage?! First rule of pi55 taking - if you can't take it back, don't dish it out in the first place.

Hmm, boilers produced by folk in the gas industry who, funnily enough, have a vested interest in future faults developing?

 

[JRP1414]

And you were playing with boiler?

I prefer to call it fault-finding. Sounds more professional.

Yeah, two things..... Pick a fight with me or gas man and you're on a loser straight away. Secondly you've just confessed to working on something you shouldn't be touching.

Bye bye cretin.

He's gone? So soon. Now where's the fun in that.

[happyflyer]
