Both plug holes upstairs gurgle when the water is draining, although there doesn’t appear to be restriction to the drain flow rate of any of them, only one of the downstairs plug holes gurgles, I don’t know if this is getting worse or I am just more aware of the gurgles.

it depends on what the cause of the gurgling is.
It could be vortexing and sucking air, putting a restriction in the drain could fix that as it would be a velocity issue. (the extra height in the siphon would aid that and cause it to be more prominent upstairs)
My toilet gurgles when I empty the water out of the bath. Even though it’s not in the same room.

Thanks stumpy, there doesn’t appear to be any significant restriction to the drain rate, even when the tap is blasting directly into the plug hole.

That sounds a bit weird Mr car?
Plumbing is often mysterious.
Shuddering in the plumbing was often a problem in the old cottage down Mole Creek way. Violent shuddering of pipes, especially when the water was getting too hot (heated by woodstove).

Plumbing is a mix of voodoo and witchcraft
My house has a tap that will “hammer” but only if the toilet was recently flushed. It isn’t connected to the toilet in any obvious way and is the only tap in the house that does it…

put a non return valve as close to the tap as possible
I’ll get maintenance onto it…
Possibly a vent in the line is either not fitted, blocked, or the level of the water is high enough in the pipe work to stop it doing its job, causing air flow back through s&p traps as liquid flow displaces air in drain pipes. A partial block or restricted flow downstream can do this. Also a a lack of run off/drain angle in the plumbing can variously contribute to this.

Not necessarily. I’d say that bubbles toilet system and bath drain share some infrastructure. It is a country drain after all.

You forget that the water supply to the rest of the house is usually the same water supply to the toilet cistern.

Ballcocks can contribute to hammer in lines, & Pressure Regulator Valves can motorboat too. Any ballcock not solidly fixed can be part of a or contribute to oscillation/s of sorts in a pressurized arrangement. It’s perhaps not so much the wave as the pressure of the water hits the water in any container (though this can be part of it), it’s more the support of the ballcock that flexes. Not return valves may play a part too.
Lots of things contribute to hammer in lines but the very first in the line is the plumber that installed the system.
Backtracking his faults can be tricky. The first things to do are to reduce pressure overall or reduce pressure at high pressure points. Hammer is often caused by not placing enough stirrups in places that need more.
Funny stuff, plumbing. When I turn on my garden hose, the HWS fires up momentarily and then the fan runs for a few minutes.

No.. that’s electrics.

Easiest fix is anti hammer tap washers or a blanked off air filled riser.
small pressure tank with a rubber bladder works well (they market 1litre ones as ‘water hammer arrestors’ but i’ve mainly sold 2 litre ones for this use.
Easiest fix toprevent damage as i said before is nrv near the tap

Nearest to the tap is bestest.

OK, so the you-beaut ceramic washer mixer taps are great. Even with the pressure reducers inserted in water saving devices, the lever action still allows you to flick it to full. This is similar to what a washing machine does when it asks for water. A ballcock can be set at full pressure or less.. I recommend turning the tap nearest the ballcock inlet to.. way less.

Yes. Gurgling is caused by the motion of trapped air bubbles. This applies both to domestic plumbing and human internal plumbing. For some pretty pictures of what is actually happening do an image search for “multiphase flow regimes”. Gurgling can be temporarily reduced by either filling the basin to a lower level or applying some swirl to the flow before or after the plug is removed. The swirl provides a central channel for air to escape up the pipe as the water flows down.
For a more permanent solution you would need to change the plughole (for example by adding or removing a plastic or metal insert) or replace the basin.
