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...

Grant Vortex 50/90 condensing oil boiler where the air tube spigot over the fan is not connected to the existing flue, should this be closed off with a Reillo cover plate to stop vermin getting into the open fan motor.If is blanked over will need a further combustion test to confirm adequate...

when I removed the back coal saver I can now see the mental back boiler. I could not see the back boiler when I put the coal saver in place last year . Do I recover the metal back boiler in fire cement or is their something better. The fire cement at the bottom of the photo is where I block...

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...

Good morning! I have a dripping tundish, so decided it's time to replenish the air gap in my Megaflo - something I've done from time to time in the past. So I've turned off the water, opened a hot tap, and then tried to open the pressure relief valve on the Megaflo. But it's stuck: the plastic...

Hello, I need to open this manhole / drain inspection cover but not sure what type of key is needed. Does anyone know? Photo is of the 'keyhole' There are no other features on the cover (concrete) except for some unreadable letters.

Hi guys, We have an open vented heating system and a Worcester Bosch greenstar boiler. Recently there is little to no heat getting to all radiatiors. It seems that when we turn on the nest heating the boiler starts whirring as expected as then dies down quite fast. I cleaned the magna filter...

Hi all, I wonder if someone can help. We have a Worcester MT10 combi boiler that has a fault with the expansion vessel. The landlord is having the boiler replaced this weekend, but in the meantime I was advised by their plumber to top up the pressure each morning (as it's currently dropping...

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've just had a brand new combi boiler installed just a few days ago. I've noticed that the boiler will fire up randomly with the tap light flashing meaning it's providing hot water. The only issue is no hot water taps are on/open so I don't understand why the boiler is firing up thinking a...

Recently had boiler issues heat exchanger was replaced but water would still go Cold Randomly especially in the shower. Engineer says Combi boilers can only provide hot water if the turbine is spinning at max speed so you have to open the tap at 100% to get hot water. So he removed(broke) the...

Just a quick tip for all the people on the site due to the rediculous price of energy we are all looking where savings can be made , I have recently been contacting the boilers I install to work on open therm this doesn't work for all boilers but a modern combi is usually compatible, it's worth...

Hello I have no experience in this industry. A few years ago our home was completely stripped apart, remodelled and extended. This required new hot and cold water pipes all over the house, a larger boiler, larger tank and so on - see attached. We wanted the water tank to go into the loft but...

Sorry for stupid question but if you don't know you don't know. Can I turn off the 'bypass radiator" in the hall (has no TRV) as long as I keep another radiator, (any other, somewhere) open? Or is this bypass radiator somehow plumbed differently and must never be closed?

This basin tap needs a washer change. How do I get in it?

Hi, I've recently bought a house and the drain is open in the conservatory. I think it's an old clay grey water drain and has the pipe from the kitchen sink coming out the wall about two feet up and running straight down into it. My idea is to redirect the pipe to come out the wall under the...

Since one year ago, almost every time when opening any taps at my home, the whole pipe is rattling, very noisy. I got A plumber installed a few water hammer arrestors. But it doesn't work at all. Does someone know what cause that please? Thanks!

We got an open fireplace with a back Boiler it also feeds the radiators with a pump, the water goes via the back boiler through a coil under a hot water cylinder heating the hot water. My question is, if the hot water would be connected to a pump EG pumping the water passed the back boiler...
