As you said 'Both' are leaking are you missing a washer or something from each connection?

Thanks all, its done now thank god. 16m2 of 70mm screed by myself has took nearly all day and I'm knackered :lol: I tried an initial wetish mix (it didn't self float by any means but was easy to tamp down into the mesh and pipes) and very roughly floated the top. By the time I got to the...

I've read a lot of sites and discussion all pointing to floor screeding being a fairly dry mix (4:1). Squeezed in the hand it should retain its shape etc. None of what I've read discusses what happens if you make it too wet? I'm putting a 70mm 4:1 sharp sand screed over water under floor...

Don't forget the floor when you've done. Even if it's a solid concrete one now you'll need to somehow damp proof it or anything you store will get rusty/damp.

I'm intending to lay a concrete floor with water UFH, but I'm reading conflicting advice when it comes to the order?? To me the logical order would be ... 70mm screed with pipe work in and either mesh or fibre reinforce 100mm insulation foam 100mm Slab concrete DPM Binding 10mm...

Yeah, I know that's the right device but the supplied fitting for the filter has a huge thread on it , the same size as a radiator valve. If I use the above I still then have to get the up to the correct coupling size which then requires another piece. Unless the above comes in a...

New fridge freezer, needs plumbing in for the cold water drinks dispenser. The supplied fitting to connect the filter to the water supply has a size and thread equal to a radiator valve (the other end is to connect to 6mm plastic pipe) . Is there any reason I can't used this as my shut off...

Thanks for the help all. Was confident enough about the anxillarys being ok to go ahead and buy a new PCB. Fired up straight away.

I'm with Flameport here, it sounds like your Thermostat is internally faulty. When it switches the supply off it shorts to earth (tank) somehow. Get a new one and replace just that bit, not the coil, I don't know if you've removed it before but its just dropped inside a tube. You don't have...

I was trying not to be too technical here. I originally posted ~0Ω which is 'approximately' 0 taking into account lead resistance etc. What do you mean by OL ? Thanks very much for that , just what I was looking for.

Just thinking about somethign else, is it definitely an MCB you've put it on and not an RCD? (An RCD will have a 'push to test' button) Your problem just doesn't seem to add up. If it can heat for two hours and then trip I wouldn't think there is any break down in insulation . By the sounds...

ffs sorry. Brain fart. [email protected]

As with all cross manufacture these days you'll find your clutch is actually exactly the same as a vauxhall Corsa. Try any cheap motoractor and you'll get one. :D

It has 3. Am I right in thinking it has two pipes to check the 'negative' and 'positive' pressure created by the airflow entering and exiting the system. ? My email address is [email protected]

? What do you mean? or are you refering to Everest ? I've noticed his trolling in the other topics , hence I didn't reply ;)

I am begining to suspect the pcb may have gone to silicon heaven. before I order one I need to check all components connected to it to make sure one of them isn't dragging it down. Valve coils - Both have some reading, not short or open so I'm hoping they're ok. Thermostat and over heat...

If you're saying the thermostat should be 1MΩ at rt , does my 600KΩ suggest a problem or is that a 'thereabouts' kind of reading ? The pilot valve coil reads 1.5KΩ, the gas valve coil reads 65KΩ. Your comment about "the pcb checks the resistance of the solenoids...

So the Overheat stat is ok, cause it currently reads 0 Ohms which is closed.

It reads 0 Ohms, ie short cct. Sorry if I confused the issue by putting ~0 , that means approximately 0. I assume it would go open cct when it activates because of overheating? Or are you saying it should be open cct, and then closes when activated? This isn't usually the logical way with...

There are two sensors on the water pipes. According to the PDF manual they are :- Thermostat sensor and Overheat Thermostat. The fault finding chart suggests checking them with a meter but isn't clear as to the readings expected. I'm electrical/electronic trained and can't understand what...
