Guys,

Need some help, had the plumber in & e has done a load of bits including putting an upside down pump the right way up. He has not done everything agreed so we are a bit p1ssed with him but the problem is the boiler keeps tripping out on the overheat now & we can't get any hot water or heating any ideas on what the reason for the repeated overheat could be?

Was it doing this before your plumber made any alterations?

furrybloke · 15 Sep 2007

No, was working but had to have a new 3 point valve as it was not switching over.

The first thing to do is to establish whether it really was on upside down, then is it spinning, then is there water in the system.

After that, the solution will be obvious.

The pump was upside down originally. My wife phoned him & he said it was upsidedown due to the way the system flows. I asked the new plumber he said it didn't matter which way up it was??? The pump is running.

We never asked him to touch the pump just the valve.

A pump has to be the correct way up as the system will be designed for the water to flow one way only

The boiler going to overheat at it's simplest would be lack of flow through the boiler. Check the pump valves are open fully and check the arrow on the pump casting for flow direction. It should flow from the pump to the 3 way valve.

Is there a bypass fitted?

So why did he change it?

Anyway, is there any heat coming up to the "AB" port of the motorised valve?

Pump flows towards the 3 point valve now, is that correct? All pipes are hot. The boiler hasn't tripped for about an hour so fingers crossed (longest all day). I am going to grab a shower whilst I can. I have turned the boiler down to 1 from 3 out of 6.

Thanks for your help I will let you know how it goes.

furrybloke · 15 Sep 2007

Got nothing to do with no being happy p1ssed when someone says they work till 6 & sod off @ 4:30 each day & then tell you they need another half day!

Left some bits in that should have gone & took out bits that could have stayed!

So Yeah I am bloody public

Mailshot his neighbours and tell them what a tosser he is, he is sounds like he deserves it. Its the only way I can get back at the cowboys round here.

hi-spec plumbing heating · 15 Sep 2007

ya see so you never said you'll work late then change ya mind and go home

he's only human to his entitled to go home at a sensible time aswell

or is it what they say i can but you can't.

gas4you · 15 Sep 2007

I never tell customers a time that I will go each day. It can vary between 3.30pm and 6.00pm depending on what stage I am at each day.

As I only work on a fixed price quote it does not matter how long I take or my start/stop times each day as long as I get the job done.

Obviously the faster I am the more money I make

furrybloke · 15 Sep 2007

Gas4 if the guy had done that no problem the fact is we are having huge amounts done & it is being done in piece work he said he couldn't fix a price so agreed to 2 days work till 6pm & had to do as much as possible & complete certain jobs which allowed the next stage of the work. This is the fall down area.
