vent
A hydrothermal vent is a fissure on the seafloor from which geothermally heated water discharges. Hydrothermal vents are commonly found near volcanically active places, areas where tectonic plates are moving apart at spreading centers, ocean basins, and hotspots. Hydrothermal deposits are rocks and mineral ore deposits formed by the action of hydrothermal vents.
Hydrothermal vents exist because the earth is both geologically active and has large amounts of water on its surface and within its crust. Under the sea, hydrothermal vents may form features called black smokers or white smokers. Relative to the majority of the deep sea, the areas around submarine hydrothermal vents are biologically more productive, often hosting complex communities fueled by the chemicals dissolved in the vent fluids. Chemosynthetic bacteria and archaea form the base of the food chain, supporting diverse organisms, including giant tube worms, clams, limpets and shrimp. Active hydrothermal vents are thought to exist on Jupiter's moon Europa, and Saturn's moon Enceladus, and it is speculated that ancient hydrothermal vents once existed on Mars.
The soil pipe from my bathroom passes through the outside wall and into the roofspace above the adjacent single storey kitchen before dropping into the ground at the end of the kitchen (about 4.5m out). The existing vent riser comes off outside the bathroom and rises through the roof on the...
Hi
I recently did some pipe insulating in my loft.
The only two I didn't do were the vent pipes. Not sure if that is the right term for them? They are the pipes that feed water back into the top of the tanks when there is excess, presumably from steam, expansion, etc. The one going to the cold...
Dear professionals, could someone kindly advise on per below issue, please let me know if more pictures or details needed. I think my Auto Air Vent is now leaking. A little background on the boiler – installed a year ago in Feb, Valiant Heat only boiler Eco Tec plus 424, plus new pump. The leak...
Hi, I'm new to the forum and just some background on myself. I have 4 years experience as a plumber but haven't worked in the trade in 15 years. I would say my overall knowledge is not great as I did most of the 4 years working on rinse and repeat estates of houses. I was also quite young and...
Hello all,
I'm preparing an estimate for a bathroom renovation in a block of flats. As always I'm trying to flag up / plan for and cost as many possible unknowns as possible in advance. One thing that I've not seen before is the ~50mm pipework connecting into the soil stack (see picture). My...
Hi all,
I have an old toilet on the top floor (to be removed) which empties into an outdoor vertical SVP and into the ground. The pipe is straight with a vent terminal on top.
Another toilet on the ground floor empties through the suspended timber floor into (what I suspect) a drain.
I wish...
Hi,
I'm wondering if this is allowed or will work in the UK. We currently have all our waste water connecting to a single vented stack. The pipes from the toilets etc connect to the vertical stack via a horizontal pipe as you would expect. I'm about to renew all the soil pipes. We have 2 entry...
Hi all I am just after a bit of advice.
I'm buying a new house with a downstairs bathroom. I can not see a vent pipe on the outside of the property or an AAV in the loft. It's a terraced house, so thought maybe it shares the neighbours vent stack?
It look like all the waste pipes go down...
What would be the heating time for this (indirect) vented cylinder? Rated coil = 14kw
Is it 96 litres x 4.2 specific weight x 40 (dT) ? How do I calculate the heating requirement of the boiler to heat this cylinder.
Secondly, they are simpler to install as opposed to unvented type but what are...
Hi, I'm after some help regarding my Father in laws heating system.
He has had a local engineer around but hasn't had a fix and is very remote so I'm looking at the issue before arranging someone to try to fix. He is on oil and has a modern raeburn boiler/range. He has a vented system with...
I currently undertake a plethora of jobs for a client and they have states that they have an unpleasant smell emanating from their bedroom. On inspection there is a box section with 2 circular vents on each side where the horrendous odour is coming from.
It looks like during construction of the...
Hi there
I have an existing soil stack on the side of my house. I have extended the house by building a loft.
The loft company ran the waste from the loft over the roof straight into (i.e. closing off) what was the soil pipe - and added an AAV at loft level.
However now I am reroofing and...
Hi guys
Is it normal for the cold feed pipe from the f&e tank to be combined with the open vent?
The cold feed connects to a 22mm tee one end is the vent the other cold feed to rads
I thought the vent connects to ch flow and the feed to ch return?
Thanks in advance
I recently took off an end stop on the vent/expansion pipe over the heating header tank. I now know why it was capped off. When the 2 way valve opens to heat the hot water, water pours out of the vent pipe. I had a heating engineer out, he said get rid, open vented systems are now obsolete...

im attaching a basic diagram of her floor plan and would like to hear some ideas of how i need to vent this
the ceiling will be cathedral so that will make this more difficult
thank you
Hi all,
So I re done my house 2/3 years ago and had all my radiators taken out on the lower floor, changed to wet underfloor instead. 2 zones. 2 manifolds. As I was doing quite a bit, I’d decided to exchange the two 15 year old boilers with a pair of new ones. Vitodens 100w 35kw open vent...
Hi, I would be grateful for any advice regarding regulations on installing vent pipe. My landlord has recently hired a handy man who installed a vent pipe for him but he installed it in a way that is it placed on the outside wall, only 50cm under our window (1st floor window). It feels to me...
Have a ground floor hot water cylinder, want to boost hot flow to upstairs bath with inline booster pump. Can't get to pipework near bath, so wondering if I create a new dedicated vent tee'd into pipe just after it leaves the cylinder, then install pump after new vent, and cap off old vent at...
I have to connect the UPVC pipe to the ground. There's a connection of sorts there already. The rubber gasket there has perished but I don't seem to easily find a replacement.
Even if I did, the old UPVC pipe I have doesn't fit tightly in there and presumably never did.
My question is, does...
My builder has removed the soil vent pipe stating that an AAV would suffice.
As I have had some troubles with them I have started to question what they say so I have done a bit of digging. From the internet I don't seem to find a clear answer about this.
Could you please clarify this for me? Do...
