Have you actually checked the tyre pressures with a manual pressure gauge?

I recently bought an endoscope (2 metre cable version) for the grand sum of £1.52 including shipping from China !) and also found it kept losing the USB connection, when used with my Moto G14 phone and the manufacturer-suggested AN CAMERA app. However, when using the nExt CAMERA app (free of ads...

For a given pressure differential between the two ends of a tube the flow rate is theoretically proportional to the fourth power of the radius, and flow resistance is the inverse of that. So for the same lengths of tube with the same pressure differential, going from 15mm to 22mm reduces flow...

Without the 'not' you'd have B&Q's website.

Is that a drip of water or paint under the right-hand end of the draincock?

Is that bolt removable? If so, you could file the lower end to reduce its diameter just enough to fit inside your reduced-length tube, then drill through tube and bolt diametrically and fasten the two with a pin through the drilled hole.

What does this tube attach to at the ceiling fitting? A downwardly protruding bolt?

Isn't planning consent now required for a non-porous driveway?

It shouldn't make any difference. See post #3 re the intended water level.

Thanks guys. I was hoping to do a quick swap of an isolation valve, re-using the old valve's nuts and olives. I'm guessing the old (weeping) valve dates back 10 years or so. Doesn't look like a Prestex one.

Is the thread size of nuts on 15mm compression fittings (specifically isolation valves) in the UK standardised, or does it vary with manufacturer?

Off-cut of garden hose?

I had a similar failure with the half of a double socket used for the kettle, i.e a fairly high current. Inside the switch is a brass rocker strip. One or other end of the strip lands on a contact to complete the circuit. My theory is that the heat developed when the contact wears results in the...

Why the spare screw stuck in the plastic (pic #1)?

I'm surprised planning consent was given (assuming it was).

Cartridge=gland. The O-ring is halfway down the gland. The valve seat is in the tap housing and shown in post #11.

Try a thinnner O-ring/ rubber washer on the cartridge, so that the blue seal can press fully against the valve seat.

That's not normal vibration. Possible causes: Not all feet touching floor, Excessively unbalanced load, Machine case touching a kitchen unit, Worn/missing vibration damper, Loose/broken component.

The solder should flow all round if the parts are well fluxed, but it needs sufficient to penetrate well into the joint by capillary action. If the valve contains a seal, be careful not to damage that with excess heat.

It depends on the power of your heat source, and whatever other pipework you have connected to the T (which will conduct heat away from the T). Clean and flux the parts to be joined, assemble them, and heat up until solder applied to the joint area melts freely and gets drawn into the joint.
