Curing Your Cold Radiators

It’s getting cold out there and the last thing you need is a faulty heating system.

Is one of the radiators in your house not heating up when the rest of them are?

Here is a check list you can go through before calling your heating engineer which could save you time and also a bit of money.


  • First, check that the radiator valve isn’t turned off. this can be turned on by hand or if the wheel head is missing, you can use a small adjustable spanner.  Make sure it’s fully open by turning it anti-clockwise.
  • Do you have a thermostatic radiator valve fitted? if so is it turned off or down too far?  Or is it faulty?  One way of checking if its faulty is to remove the head, you can normally do this yourself by unscrewing the big nut that attaches it to the body of the valve. If it is faulty the radiator should immediately warm up after taking the head off.
  • Another reason radiators stop working is sludge.  Valves and radiators can get blocked by sludge and the only way of getting rid of it is to clean and flush the system out.


We always recommend seeking the skills of a competent, Gas Safe Register approved heating engineer so if you are unsure or it’s gas related please call your local Gas Safe Heating Engineers.    

Topping up the pressure on your Worcester Bosch combination boiler using the internal filling link and key

We get a lot of customers calling us because they are unsure on how to top up the pressure on their new boiler using the internal filling link.


If the needle on the pressure gauge on your boiler has gone into the red or down to zero it means there is little or no pressure left in the heating system and it needs to be topped up ASAP. So here’s Gas Care Swansea’s guide to refilling your Worcester Bosch combination boiler through the internal filling link.

  • First you need to slide the under carriage out from beneath the boiler. this comes off pretty easily, just pull it towards you and it will eventually drop down.
  • You will see attached to the under carriage a white filling key. Take the key out from its holder.
  • Now you need to locate the filling manifold. look under the boiler and you will see a black plastic filling manifold with a plastic nut next to it.
  • When you have located the filling manifold you then need to insert the key. if you look closely at the manifold you will see two padlock symbols, one is locked and the other is unlocked. Now look at the key and you will notice that the edge of the key is shaped like an arrow. insert the key so the arrow is in line with the unlocked symbol. make sure you push the key all the way in then turn it clockwise to the locked symbol.

  •  Now the filling key is in the correct position you can start to fill the boiler. slowly turn the white (or it can be grey) plastic nut next to the filling manifold anticlockwise until you can here water flowing into the boiler, keeping an eye on the pressure gauge on the front of the boiler. when the pressure is at the desired level (1-1.5 Bar) close the nut, take the filling key out and replace the under carriage.


  • When removing the filling key you may get a little bit of water dropping out so its a good idea to have a cloth ready to wipe up any excess.
  • If you accidentally over pressurise the system don’t worry just vent a few of the upstairs radiators and this will bring the pressure back down.

Noisy Water Pipes

Water Hammer. this is the most common noise found in household water pipes. it can be caused by few things but generally its main cause is unsecured pipes. hot and cold water pipes need to be clipped, if they are not they will make terrible sounds when water draw offs are opened and closed. the cure is pretty straight forward really, locate the unsecured pipe and secure it.

the best clips to use on existing pipes are nail clips as they are easily fixed over the pipe in position, you can find these is all plumbing merchants. Basically you just hammer a few over your wobbly pipes and this will solve the problem straight away.

Worn Tap washers These can cause a lot of water hammer when taps are opened. when washers start to wear out they allow unregulated water through the tap this lifts the tap insert up and down very quickly making a terrible noise. To solve this you just need to change the washer in the tap.

Noisy water pipes in the home can be very annoying and to the untrained ear can be a puzzle to solve. so follow these these Gas Care Swansea – Plumbing Tips and solve your noisy water pipe problem.

A good tip in finding what pipes are causing the noise is to note when the noise happens and whats being used e.g are you using the shower? is the washing machine filling? does the noise happen when you turn the heating on?

Then you need to try and locate the noise. listen around the house while someone turns the tap on and off or when the heating has recently been turned on.

Next, what sort of sound are the pipes making?

Creaking Pipes. A creaking sound can be caused by the water in the pipes heating and cooling making the copper expand and contract. One way to solve this problem is insulating the pipes using pipe lagging, this will slow down the rate the pipes heat up and cool down, reducing and even stopping the loud noises.

Other noises can be a bit more complicated to solve and will probably need your local plumber or heating engineers help. Banging sounds from the boiler can be caused by many things and will definitely need a Gas Safe registered Engineer to look at it.

How To Stop Dripping Taps

How To Stop Dripping Taps – A Step By Step Guide

If your tap is dripping and no matter how hard you turn it, it won’t stop, it’s because the washer inside the tap has perished. So here’s Gas Care’s step by step guide on how to stop dripping taps.

  • First things first, you need to locate the stop cock (this is normally under the sink in the kitchen or if you can’t find it, it will be outside under the pavement). Then you need to turn it off to isolate the water supply.
  • Take off the lid of the tap (the part that indicates whether the tap is hot or cold), usually I’ll use a stanley blade or small slot head screwdriver.
  • Under the lid there’s a screw, you need to undo this to take the tap head off and reveal the tap insert.

  • Next, you need to undo the insert.  For this you’ll need an adjustable spanner, be careful not to turn the entire tap though (you may need someone to hold it for you). The insert will have a hexagon head for the spanner to fit.
  • When the tap insert is out, turn it over and you will see the tap washer.  You now need to separate the washer from the insert.  Sometimes there will be another tiny nut holding the washer in position, if so you need to undo this too.
  • Next, give the seating in the actual tap body a little clean, also it is worth giving the insert a rub to make sure the new washer sits correctly in position.
  • Replace with the new washer and put everything back together.


If you’re unsure of the correct size  of the washer then once you have taken the old insert out you can take it to your local plumbers merchants, show them and they can advise you. It’s a good idea to either keep the washing bowl in the sink or keep the plug in so you don’t drop any of the small screws down the plug hole.
