Good morning , can anyone tell me where I can buy 6011 weld rods either online or in the Birmingham area , everywhere seems to sell 6013 but not 6011. is there another name for 6011 as searches mainly bring back American suppliers , I am currently repairing an old 1970s bumper , the second hand...

Ok, I think its fixed , I looked at the filling loop again and the tap appeared damaged so it looks as if it has been costantly filling for I dont know how long , I Have replaced it and alls good , I was just wondering if anyone could explain what was actually happening , how could an open loop...

would this explain the fact that is yellow/brown to begin with , then clears, then re occurs? , also did it start without warning I appreciate your advice.

Roddy , Thanks for advice I will check that , did you get it replaced?

boiler make and model is ferroli optima 901 (yeah i know !!) is a combi , water is yellow , another forum suggested that as the pressure on the boiler hadnt changed that theres a possibility that its not the heat exchanger and possible a faulty filling loop? Also has only started since turned...

This morning I discovered that there was brown water coming from the hot tap only (all hot taps) , looks like the sort of thing you get when road works have taken place , however not the case as only the hot tap effected, this is obviously something to do with the boiler. Everything I have found...

I know it needs scrapping , however my finances currently disagree with me regarding that decision. Currently boiler doesnt turn on in morning, this is because pressure has dropped to 1.0 , as soon as I top it up using the loop to 1.5 it kicks in , PRV and pipes all seem fine , cannot locate...

It's only 2 1/2 years old, however it's made by montpellier and it's a pain to get bits for, the photo looks as If it's all rusted but it isn't, it's just residue from washing powder.

My washing machine was banging so I assumed it was the bearing, I spent 2 hours getting into the guts of it so now it's just an empty metal box and bits, I think I remember where everything goes, it wasnt the bearings, the "spider " at the back cracked, the picture looks like it's really...

OK, here's the full problem, the boiler keeps short cycling, the flame stays on but dies down, initially I thought as this was affecting the water temp, hot /lukewarm it was related to the water or heat exchanger, however the boiler locks out without water on, seems water just goes cold...

The pump seems to be moving the water, however Pump is getting very hot indeed, I've removed the small metal disk and it does spin freely and doesn't make a noise, please look at attached advice, is this suggesting that I turn boiler back on with the metal disc removed? Won't that throw...

Apologies for ignorance but if I open the filling loop and open a drain tap with hose attached into the drain, won't it just flush through the water until clear, I've see a youtube video where a professional removed a radiator and attached a drain to one side of the fitting and hose providing...

Then I will refill and add cleaner and then flush again and refill

Literally draining system and re filling.

I own a terraced house, the boiler is upstairs, the one Rad with a drain fitting is a step up from the others downstairs so im a bit concerned that the 3 others downstairs won't empty. Can I turn off gas to boiler, leave the cold water flow to the boiler on and attach a hose to the Rad drain...

I have an issue with my ferroli 901 short cycling , it fires up for approx 3 minutes , then shuts down , radiators seem fine, however water runs hot/warm , im assuming this is due to short cycling. i have changed the thermos on the copper pipes and the direct flow meter , ive been told its...

Yeah, I've done those, thanks, So as it stands if it's not the heat exchanger, the symptoms are, Pump is very hot which can't be right Water is hot then warm, Heating seems OK However system does seem to loose pressure when heating not on to the point where pressure is at zero, no...

Thanks , can i just clarify something please? , ive replaced the 2 sensors on the vertical copper pipes that have wires connected to the pcb (no difference) , replaced them both , however I have since seen that there are 2 temperature sensors on the actual heat exchanger , are they the ones you...

Recently I have been getting full CH however hot water runs for a while , then goes warm then fires up again then gets hot for a few minutes and then does the same , ferroli boiler optima 901 , its been suggested that its the heat exchanger , however this morning Ive noticed that the boiler...

Thank you all , I appreciate the advice , you may think that I am ignoring some of you but I am taking it all into consideration . Following on from some advice I swopped the wires so that the hot water sensor wires were on the CH thermo and the CH sensors were on the DHW thermo I discovered...
