No them, just me. That's why I'm seeking a bit of more experienced input here - looking like consensus is keep the pump, so worth my while dropping by! :)

Hello, Hoping you with more knowledge + experience can help with a quick query.... please :) One of the pump valves started to drip badly this week from the spindle, so I've got them out to replace, so have the pump out. Pump is a Grundfos UPS 15 50x18 Model C No U748 MKII - see picture...

AFAIK is should follow those fundamentals. Remember that on a pumped system the pump will still run and make noise all the time - it's just the burner that cuts out; perhaps the pump has been inside the boiler and it's that you can hear? Or perhaps a combi/some boilers can modulate down to a...

Usual for all boilers I think... my understanding of how they work... 1. Thermostat calls for heat because the room is colder than the set point. 2. Boiler fires up and heats the water in your system up to the temperature set on that dial on the front of the boiler. 3. When the water in the...

Won't there be a stop cock out in the street somewhere that you could turn off? I'm fairly ignorant to whether this is normal or not - but I've always had one, next to the meter if you have one of them.

This is worth a look too: https://www.your-loop.com/product/dual-fuel Monitors your gas usage rather than boiler on/off - so may not give quite the resolution you are looking for.. and not the cheapest thing in the world by the time you need dual fuel. But in my experience it is solid/reliable...

Warning pipe - I presume that's what a novice like me calls the overflow? The white plastic one that takes the excess from the tank to outside? If so - then yes, from memory the water level is only 15mm or so below that when system is cold. I shall endeavour to adjust the ball valve to keep the...

That's what logic tells me... no loop to pump round, so it can't... Yet sometimes the overflow is dribbling outside when the heating is on - never seen it when the HW is on, but guess I can't 100% rule it out as it only happens sometimes with the heating on - maybe I've just never seen it when...

Interesting; pumping over problems are my reason for trying to get a little bit more familiar with the system. There may well be more questions along that line once I've ruled a few other things out.

Yes, three pipes. And pretty much as you say. Bottom two are feed in/out - right hand bottom is flow from boiler, left hand bottom goes to the pump. Top has a single pipe - combined vent/feed. It goes up to loft, where it splits just before the tank to separate vent/feed.

Sorry, hadn't realised it didn't show - image was showing for me as logged in to where it's hosted. Should be working now. Something along the lines of an air separator was my best guess; house built in late 80s, but I'm not a plumber.

Hey, Could someone tell me what this chamber is for/what it is please? Pipe out the top is the feed/expansion into the heating/dhw circuit (single pipe for both, splits in loft just before header). Right bottom comes from boiler, left bottom goes to pump. Assume it's something to do with...

I learnt something anyway! :)

Ah, that's another option, assuming it's not yet made it to the skip - thanks :)

It was wound yeap; the bulbs are halogen and not led though.
