Random Intermittent Trickle/Dripping in Bathroom help.

Sounds like you should ask the plumbers who installed the new bathroom why their work is leaking. New fixtures shouldn’t be dripping 24/7 like that

Plumber saying he doesn't know what's causing the problem and he is saying that it must be the new fixtures I bought are faulty that needs to be replaced.

He said because they are faulty I am liable and hence I have to pay extra to him to remove the fixtures to be replaced.

Hence why I came here to ask questions to see and verify whether the fixtures are faulty or what is causing the problem?

In the absence of any further technical suggestions, this is a consumer rights issue. Suggest you ask the question on the Consumer Rights board on here to get relevant advice. All the best with it.

That was my first thought. Noticed it here: very cold mains water at this time of year — below 6 degrees at my gaff. Water sits in tap spout and slowly warms up towards room temperature. Volume/viscosity change is eventually just enough to cause a sudden trickle..

Shower heads seem to hold a lot of water and take forever to stop dripping. Ive sometimes left the handset on the floor of the bath/cubicle to avoid Chinese water torture at night

.

I was just looking at this thread again. I reckon it's this.

If the tap is the "mixer" type where the outlet goes "up and over" there is water sitting in the outlet. Same with a shower.

A water pressure problem would most likely give a steady drip once all the other outlets were closed.

Something I have noticed with our shower is that it will occasionally have a drip if a door is closed somewhere in the house. The slight air pressure disturbance must cause the water to move enough to start a small trickle I'd assume.

OP states that it is 24/7 drippage though. The only other thing i could think of is when you get a closed section of pipe between a check valve and outlet. When that fills with cold water and then slowly warms up, it can produce very high pressure, but again it wouldn’t be 24/7. <Shrug>

Yes it is a mixer tap. The tap outlet is straight hotozontal instead of a up and over outlet tap.

I recall a post mentioned earlier in this thread saying stopcock has nothing to do with pressure. If so how do I adjust water pressure?

How does closing a door cause your dripping? You mean if you slam the door hard affecting pipework near it or closing the door affect air pressure in the room?

The shower head is 24/7 dripping because the shower head is connected to a hose that builds up water and holds the water that makes it constant dripping I believe.

Do you mean isolation valve when you say check valve?

As I said in an earlier post. A stopcock does not reduce pressure, You need a pressure reducing valve as I said. Something of this type I would assume.

You'd obviously need the right type installed in the correct place in your installation.
I'm not a plumber, just a DIY-er.

As to how closing a door causes dripping: I'd assume that with a fairly well sealed house it makes a small difference to the air pressure. As there is water in a shower hose it's enough to make it dribble.

Ok however previously before we replaced the old shower and old sink tap with the new ones we never had this dripping problem with our old ones so you sure its the stopcock/pressure fault?

Ok coming back to this thread what's the latest advice from my last post?
