Boiler Pressure Dropping

Are you constantly having to top up the boiler pressure to get the boiler to work?

Are the radiators not heating up to the toasty hot temperature that you are looking for? Chances are you have a leak in the pipework or a radiator on the central system.


It is at this point you may be thinking – what does a plumbing company have to do with my boiler?  We JSL Plumbing is just one part of JSL.  We also run a division called JSL Heating which specialises in the installation and repairing of boilers and all other related heating systems issues in your Glasgow home.


boiler pressure dropping


So….Your boiler is losing pressure which allows air to get into the system. Your radiators are then not full of heated water but a mixture of water and air. That means that they do not heat up as efficiently as they should. The easy fix to this is to bleed the radiators which will allow the air in the system to escape. However if you find a lot of air in the system, you may have a problem that needs a professional to have a look at it.

  • Quick resolution of problem and good communication.
  • Very friendly throughout the process. Clear information given and very thorough. I will be using them again!
  • JSL Plumbing & Heating replaced a kitchen and a bathroom tap and fixed a toilet where the cistern was leaking into the bowl. He was personable and professional, and provided advice on which replacement taps we might want to get for the bathroom. He provided updates on his progress throughout, and the pricing was reasonable. We have used JSL before and would happily do so again. Have also recommended this company to others.
  • Job completed to our satisfaction. Bathroom and en-suite left tidy and work completed in the timescale agreed and charged as per the quote. Good quality fittings used. Would certainly use JSL Plumbing Services again in future.
  • Jim assessed the leak, which required repair and offered an honest appraisal. He was on time, polite and carried out the work as planned. I wouldn't hesitate to recommend him and would use for a larger installation in the future.
  • Had a bent radiator pipe I needed replacing and as I'd already called them out thought I'd get some bath taps fitted. I'd been putting the job off as it was in a really awkward tight place and knew it wouldn't be pleasant. The plumber was happy to help and it didn't cost me as much as I expected for the time and fiddly nature of the job.
  • Very good service with work done quickly after contacting company.
