Silly question (and might already been asked 100rds of time) - I am specifying a circulation pump for the hot water secondary (circulation) return to reduce the wait for hot water. HW is coming from unvented cylinder with a secondary return connection.
The secondary return is almost straight...
Hi Guys,
Dyno have fitted a PRV under the kitchen sink in an attempt to resolve a H/W cylinder popping noise and issues with mixer taps, which unfortunately hasn’t cured the issue. I am concerned with the installation of the PRV (and the removal of the NRV) and would like to hear your comments...
I’ve just come across the matter of ‘water seal’, which i’d previously never heard of. I’m currently in the process of fitting a new shower and so I’m not sure whether I have an issue here or not.
You will see from the attached picture that the trap pipework feeds into an internal soil pipe and...
Hi,
I'm a sparky. We are installing a couple of standard S plan control systems for a couple of new domestic sized system boilers in a residential care home. We also look after the fire alarm here.
The client has just had a new tanked gas supply installed on site to supply these boilers which...
How long has it been mandatory to install a fire valve in the fuel line when installing a new boiler to comply with Part J?
Now could someone hazard a guess as to roughly how long to do the following.
1 Remove an old oil fired boiler.
2 Replace with a new oil fired boiler
3 Install a 3m remote...
I have just been looking at the back page of the Regin service forms, under item 2.4 it says "Change wheel type fire valve for remote acting type" is this a requirement that has been sneaked in and passed me by?
Are there any 3 port motorised valves (preferable cheap) that do not require a constant mains current to flow when the value is either open or closed (ie it just needs current while actually opening or closing)?
I'm trying to cobble together something for a small diesel heater to be used in a...
Hi
I am considering renting out my house in Scotland and have an lpg hob in the kitchen. I am aware I need a gas safety certificate and a mate who was an approved gas safe plumber (now retired) has had a quick look and thinks I may need a shut off valve installed under the hob, I have every...
Hi folks,
I have a standard flexible hose (the braided ones) coming off my cold and hot feed to the kitchen taps, and also one to the outside tap. I'm curious... do these need to be the flexible hose? Why not just a flexi plastic pipe with some speedy fittings? Does anything gong to a tap need...
Having a brain fade moment guys - is it an actual requirement to have an isolation valve for individual gas appliances, or just good practice?
I'm certain it's a requirement but I can't find evidence to back it up. Someone is arguing that If the ECV is within easy reach it's just good practice...
I have just purchased a flat as a buy to let. My question is regarding the Megaflow Unvented Cylinder. I understand from this forum that the cylinder should be serviced annually by a G3 certified engineer. Is this a legal requirement? If so, does the servicing engineer provide me with a...

Just wondered what everyone thought of the new boiler commissioning requirements that will come in from April 2014 that will require a CO safety test. I assume most allready analyse a new boiler installation as I do.
Hi folks,
I am quoting to fit a replacement boiler in a commercial premises, The. client tells me 3 other plumbers have told him its a requirement to also chang the HW tank now I've searched everywhere and I cannot find a requirement to do this additional work.
The tank is old and uninsulated...
When testing FSD's and hearing the 'click' a lot of hobs I test don't seem to have these, they are usually old so is that the reason? I have been putting NA on the landlord safety certificates a they don't appear to be present.
Is that correct?
We are moving into commercial catering and cant get a straight answer from gas safe...they have replied directing us to different clauses and points but not actually confirming if it is a legal requirement for businesses to get their appliences checked annually - anyone know?
Hi all
Please forgive the no doubt easy query, I'm a little confused ...
We're hoping to move into a bungalow in the next few months with an extremely antiquated central heating system. It's going to need a new boiler and rads

What do you do about FGA on a boiler like the ldeal classic nf where there is no test point and you cant get to the terminal? MI do not state FGA is required so is there no need?
Hi all,
I am really struggling to get to grips with a Worcester 24 DCi and I'm pretty sure that it's mocking me.
I have to turn on two hot water taps at any time to get the boiler to recognise that it needs to create hot water.
Once this happens, the water is only luke warm, possibly...
Are there any/many disadvantages / inefficiencies to over-spec'ing a combi boiler's heat output (ie. 40kW!) in order to get the higher flow-rate for showers, when it's then far in excess of the CH requirement (calculated just over 10.2kW or 35,000 BTU/Hr). How well do boilers modulate down...
