I have already done nearly 30k miles over 2.5 years. The car will last just fine providing you know what you're doing. I did my research before I started to avoid any issues. There was one issue that I knew would rear its ugly head - piston ring gumming. I made a decision to blend my fuel in...

They definitely were not running - I could see the vanes not moving. Anyhoo, thank you very much for replies, especially @bernardgreen for the link, it lead to a journey of discovery which ended in me buying a drill-powered heavy-duty pump off eBay for about a tenner which is doing the job...

Thank you all very much for the replies. Yes how effective it is as a pump was a concern of mine, but thought I'd try it. I'm trying to move fluids from one place to another as you say. The reason I think it's broken is because it makes noise or any vibration when I plug it in Yes the...

Thanks for the reply. I have two and both do the same thing - of course, they could both be broken. I haven't wired it wrong. Fuse is fine, pump is definitely getting juice. Pumping stuff! Cheers, Matt.

Hello all, not really a plumbing question, but thought you guys would know. I have an old traditional Grundfos C/H pump from my old system which I want to run in isolation. I've wired a plug on the end, and when I plug it in - nothing. Does it need a timer to work? What is the timer actually...

Thank you all for the replies. So the general consensus is that neither of those things are going to cut it. Will have to be an immersion heater. Great tip about trying it with the tank full. I've got decent wrenches and what not, it's just a very old manky tank. The power supply is all there...

Hello all, I am planning on ripping out my heating system when it gets a bit warmer, and I am thinking what might be the best way of temporarily heating water (taking the pressure off me a bit!). My old hot water cylinder has no immersion installed, and the blanking plug is absolutely WELDED...

Start at the header tank (the smaller tank, assuming you have two up there) and see what pipes you have exiting from it. There should be one coming out horizontally from the side of the tank near the bottom - that is the supply to the primary system. There will be another pipe which supplies...

Woops, forgot to upload the picture.

The immersion heater installation was an utter failure. I could not get the port cover off; I shocked it, banged it, swore at it, heated it, wrenched it, nothing. So I turned my attention to the gravity primary. I drained it down and ran mains pressure through the system from the header. That...

Should I bang some Sentinel X400 in there, or is that not going to help me because the problem is in the gravity part?

@Burnerman Good shout, I'll get some tape and LS-X on it. @mysteryman As you say, the blockage could be anywhere in the gravity primaries. I've drained down and refilled recently to replace a radiator valve (maybe that caused the problem!) but I did not use a cleaner/flush nor did I...

@Boilerman2 Thanks for the reply. It may appear blindingly obvious to some, but for a young chap who has only just bought his first house, it is not always so obvious. Once I have done my job for 37 years, I imagine I might find certain aspects of it blindingly obvious as well, and then I...

Thanks for the advice. One more question before I get off my butt and do it (at least the immersion heater...) - can an air lock develop over time, or will it have been there since I last refilled the system? I drained it down about 2 months ago to fix a radiator, and the hot water was fine for...

There is water in the header tank, and there is water in the pipe between the header and that tee. I will try the magnet thing. There are no air vents near or at the boiler, or at the cylinder. Just the drain off at the bottom of the system, near the boiler. If I drain the system down...

Thanks for the replies chaps. @75pete Great idea. I turned the pump up to max, turned the room 'stat up so it stayed on, turned all the rads off, and left for about 30 minutes. The upper pipe got REALLY hot.... but still nothing in the lower pipe. The pipe going up to the loft (the open...

Hi all, long time reader, first time poster. I have a very simple gravity-fed system, open vent, no valves, and one pump for the C/H. Open vent is just a tee off near the header tank. Then there is a common pipe (for both supply and the vent) going to a T on the hot water cylinder supply...
