Cisterns Liverpool

Issues with Cisterns and Ball-Valves

Our plumbers in the Liverpool area have had a lot of problems with the issues outlined in the below article. When it comes to the cold water supply in plumbing the cold water cistern and the ball-valve that goes with it are two of the main parts. In this article I will go through a few of the issues that you might come across in relation to these.

Typical Cistern

Issues with Cisterns

When it comes to cold water cisterns, there are two main issues that you will come across and should be aware of. The first of these issues is that sediments will collect at the bottom of the cistern and this will need to be cleaned out on a regular basis. The way to do this is to drain the cistern before attempting to do this. The second issue is in relation to galvanised iron cisterns and it is, of course – corrosion. If you come across a cistern that is very badly corroded you are best to have it replaced with a plastic one.

Issues with Ball-Valves

Just like with cisterns, there are two main issues when it comes to ball-valves. The first issue is that of a corroded ball and the second issue is a leak from the valve. If the ball is corroded it can suffer what we call a ‘pinhole’. This means that the ball itself will start to fill with water and this in turn will increase the water level in the cistern. This can be temporarily solved by making the pinhole bigger and empty the ball of water, before tying a plastic bag over it. If you come across this issue, replace the corroded ball with a plastic float as quick as possible.

If you come across a leak from the valve, it is most likely one out of two issues. It could be because dirt or grit has gotten into the valve or the actual valve washer could be worn. If this is the case you will have to take the valve apart and extract the washer, without damaging the piston. Clean the valve and smear some petroleum jelly on the threads of the cap and on the piston, before reassembling it again.

Useful Tips

It is a good idea to check all ball-valves on a regular basis, especially the ball-valve found in the feed-and-expansion cistern. The reason for this is that this ball-valve is not used very often and it can therefore get stuck when closed, especially if the water in the cistern has evaporated. If you find the water level in the cistern too high or too low, you can adjust it easily by bending the floating arm of a Portsmouth ball-valve but take care not to put any strain on the valve. If you are working with more modern ball-valves, you will notice they are much easier to adjust and that will therefore make your job easier. This could be a lot to take on for anyone who is not a professional, so contact any Liverpool plumber because this city has the best ones.

Plumbing and Electrical Bonding – The Liverpool Plumbers way

Back in the day when the mains water pipes were made out of galvaniser iron or lead, they were also used to provide another type of service to the building. Quite shockingly, they provided an electrical earth connection to whatever building they were servicing. Luckily, this is no longer the case. However, all metal pipes inside a building have to be connected to the electrical earth point and this is a service provided by electricity companies. There are three main points in the system that will have to have an earth connection and in this article, I will tell you a bit more about these. Being the best plumbers Liverpool can possibly give, here at Moran Plumbing, they have went into great detail on this matter, if your require further reading.

Plumbing Bonding

Electrical Bonding and the Three Mains Points

The first of these three points is the main water service pipe and this includes the main gas service pipe. These have to be earthed as soon as they enter a property. The second point is wherever an earthing bridge has to be used. A bridge has to be applied across both plastic pipes and fittings that are inserted into the water pipes and this has to be done everywhere in the building. The third point is to earth all accessible metal pipe-work that are in close proximity to any type of water source, such as basins, baths, and sinks. There has to be an earth wire running from the main earthing point, connecting it with the hot and cold water pipes – including the taps and any types of metal fittings. Generally, there are only a few electrical fittings allowed in a bathroom and they will have their own earth connections. A heated towel rail is a good example of this. These types of bathroom connections should all have been made with an earthing clamp and they should have a warning label saying; ‘SAFETY ELECTRICAL CONNECTION – DO NOT REMOVE’.

Plumbing Insurance Claims

A Word of Warning


When it comes to DIY jobs around the house, I am all for doing it myself if possible. I spend a lot of time in my Liverpool home carrying out various DIY projects. So much so, I drive my wife crazy with the noise and sometimes mess, I make. However, it is very important to remember that certain jobs should only be undertaken by certified professionals and this is relevant when it comes to electric work and any work relating to gas supply and service. Not only can you void any insurance claims caused by not using certified professionals for these kind of jobs but more importantly – you can cause an accident that will not only devastate your own house but also the lives of others. It is better to be safe than sorry so contact your electrician or gas engineer and let them deal with these jobs. Best of luck!
