Once again we’ve been busy bees this week sorting out some poor quality plumbing. We’ve been to two existing clients to investigate water coming through the ceiling and on both occasions had to make incisions within the building structure to get access to the leaky pipework.
This fitting was found inside a wall. The previous fitter had blanked off a cold water mains pipe which may have supplied a toilet in the past. The pipe continued up into the loft where it supplied the boiler with cold water to turn into hot water via the combi. The clients had lifted some floor boards and could see it dripping every 10 seconds but were unable to find the source. However it was possible to remove a double electrical socket and gain access to the small fitting behind the wall. After all the water was drained from the cold water pipe by turning off the stop cock and opening a lower tap it was possible to remove the damaged push-fit stop end and after cleaning up the end so that a new stop end would seal properly, fit a new one.
The water was switched back on and the new fitting checked for water tightness. The socket was able to be screwed back on to the wall and the floor boards were left up to allow the area to dry over the following week.
The second call out for Boiler Bee was another existing client who had a similar problem. Water was found cascading down the ground floor walls and out of light switch sockets! Once again mechanical intrusions had to be made to view the leak which was caused by a badly fitted elbow joint installed when the house was first built in 2004.
It can be seen from the photograph that the locking ring has not been wound completely down onto the securing shoulder and as a result, over many years, the “O” ring has worked its way up and started leaking. The leaking was quite catastrophic as it is in these cases, where it just “goes”.
As this fitting was located below the floor a small access hatch had to be cut into the floor to allow Derek to get his 6 legs into fix it. You can see the small hole in the picture below and the new white push fit elbow fitted to replace the grey one taken off. Its good practice to remove the old fitting as this also you to get in there with some emery cloth and clean up both pipe ends to ensure maximum success in sealing the new fitting onto the old pipes.
The photo on the left shown the new push-fit elbow fitted to the old pipes. Its a shame that such sloppy workmanship existing but unfortunately it does. However, Derek and I are here to help so if you have a cascade of water coming down your living room wall please give us a ring, we don’t just fix boilers!
Derek and I have just fitted the most up to date and high tech boiler to a property in Gosforth. The Viessmann 200W came with weather compensation and connection to Viessmann’s own internet control app, ViCare.
Unlike Hive and Nest, the ViCare allows you to look at the boiler configuration as well as setting start and stop times and temperatures. It also allows you to see how the temperature has fluctuated throughout the day and week.
The boiler we took out was a solid Worcester 24 Cdi from around 1997 which had given good service but was leaking from the heat exchanger and could require money spent on it. The clients also wanted the boiler moved to the garage which was going to be converted into a utility room leaving space in the kitchen for units and worktops.
Fitting a new boiler in a new location allowed the new boiler to be fitted in parallel with the old boiler thereby not interrupting the heating system too much. The design of the installation included setting the new boiler pipework back from the normal vertical plane of the boiler to allow a washing machine to be fitted under the boiler and allow it to be pushed right to the back wall. In line with the current building regulations the walls in the garage had to be insulated to this done before hanging the boiler. Services were T’d off so that the systems could be extended in the future and the magnetic filter was placed in the under sink cabinet to allow easy access when servicing.
The pipes were then insulated and covered over with the plasterboard hatch to give a flat back to the space.
The flue was extended by almost 3m to take it to the front of the garage and through the brickwork above the garage door.
The final stage of the process was to disconnect and remove the old boiler making good the old connections and flue penetration. This was completed and the boiler handed over to the customer for them to get to terms with the extensive functions available on the 200W. The photos below show the process of making good the old flue penetrations:-
Viessmann boilers have won accolades from Which? testers for many years and now consider themselves as the most reliable boilers in the UK. When installed by an Approved Viessmann engineer (us) they carry a 10 year warranty*
We were called to a property in Holystone to look at a Gledhill Boilermate II. It had stopped working, there was no hot water, no heating and a clanking sound from the Potterton boiler. These are classic signs of poor circulation and sure enough after testing the electrical supply we found that one of the pumps has seized. The pumps are located in the airing cupboard to the side of the hot water cylinder and have been squeezed in place with no real thought for how they could be serviced in the future. After the isolation valves failed to stop leaking we were forced to drain the whole system and replace the isolation valves and two pumps as can be seen from the phone above. The whole job took about 5 hours but was complete and is mowing working – leak free.
We are absolutely delighted to announce that we have received over 500 reviews of our work on our Checkatrade web page over the past 2 years.
Over the pass 2 years we have repaired numerous boiler, installed new boilers, fitted new radiators, serviced gas fires, fitted wash hand basins, showers and sinks. We have flushed pipes and installed new pipes where needed; we have fitted underfloor heating and a whole host of internet and conventional electronic controllers on to existing, Y plan, S plan and combi boilers.
Over those two years we have received 435 10/10 scores and 98.8% of our scores are 9 or above. This is a testament to our missions which is to fix your boiler (and other plumbing items) offering you a great service and exceptional value for money.
As 2018 draws to a close, we hope to be able to serve you throughout the 2018 winter and into 2019.
After a little hiccup with the roof the water tables finally went on and the roof was complete
The next job was to get the floor ready for the screed next week which meant digging out my and Derek’s underfloor heating installation skills. With 100mm of insulation down we laid the 240m of 15mm heating pipe and secured it with staples. Now it’s ready!!
Derek and I have been very busy educating people about expansion vessels and fixing boilers.
If your boiler is loosing pressure on a regular basis and you have to keep topping it up via the filling loop it’s MOST likely that there is a problem with your expansion vessel.
In a pressurised heating system such as a modern combi, the water in the radiators is pressurised in a sealed system. Like all water, when the circulating water is heated, to provide the heat in your radiators, it expands. When it expands it needs somewhere to expand to and this is where the expansion vessel comes in. The expansion vessel is filled with pressurised air at the same pressure as the system so that it retains a certain volume. Once the boiler starts heating the circulating water the expanding water is forced into the expansion vessel and compresses the air in the vessel to thus allows vessel to accommodate the expanding water. When the system cools down the reverse occurs.
Problems occur when there is no or very little compressed air in the expansion vessel. When it doesn’t have any air in it is when it fills with water and water is NOT compressible and so doesn’t provide a space for the circulating water to expand.
What happens next is key; the pressure increases in the system and the pressure relief valve opens as a safety device to expel some of the excess volume. This can be seen as water dripping from the small copper pipe at the back of the boiler, usually in the back yard.
When the system cools and the circulating water retracts to its original volume there is less water in the system because some of this water has drained out of the pressure release valve. This results in lowering the pressure and sometimes the boiler will shut down as a safety measure because of low pressure. The user then adds water via the filling loop and the whole process begins again.
Some “plumbers” will say there is a small leak or that its normal to have to keep topping up your boiler – THEY ARE WRONG!!
The expansion vessel is full of water and needs to be serviced.
Most manufacturers service manuals state that the expansion vessels is serviced on a regular basis.
So if you are finding that your system water constantly needs replenishing then it most likely your expansion vessel, which is a relatively straight forward job for a busy bee 🐝.
Progressing on now with great gusto, our roofers arrived on site this week to start the roofing work to cover the structure in Welsh slate.
They have hand selected the best slates that were taken off and mixed them all up in a random fashion so you can’t tell if they were facing north or south. The remainder will be sourced from a local reclamation yard and cut to size the match the original slates.
After a 10 week wait we finally saw the arrival of the oak trusses – very excited and impressed 🤪
Unfortunately they arrived on a 65ft artic but with the aid of a neighbouring farmer were carefully transported to site ready to be lifted on by the 14T crane.
Lady Luck really looked down on us as we had a great window of fine weather until almost complete when the heavens opened but by that time we had the trusses protected with polythene and we had complete most of the roof structure including the insulation.
Our team of roofers arrived bang on time to “black out” the new roof and now we are completely watertight able to continue with the internal electrical and plastering work.
