What is included in system maintenance.
System maintenance is the preventive side of our plumbing work, and a visit covers both the water side and the heating side of the system. Your annual boiler service is a separate job, because it is gas work on the boiler itself.
Pipework and joints
We look over the pipework we can reach, under sinks, in the airing cupboard and around the boiler, for weeping joints, corrosion and the green staining that shows a slow leak on copper. We also point out pipes in cold spots, such as the loft, that need lagging against frost.
Valves and stopcocks
The main stopcock and the isolation valves are checked to make sure they still turn off. A stopcock that has seized is no help on the day a pipe bursts, so it is better found now, and we make sure you know where yours is.
Hot water
We check the hot water reaches the taps properly and at a sensible temperature. On a cylinder system we look over the cylinder, its valves and the immersion heater, and tell you if it is getting close to the point where a cylinder change makes sense.
System pressure
On a sealed heating system we check the pressure and top it up if it has dropped. If it keeps dropping, water is getting out somewhere, and we look for where it is going.
Inhibitor and magnetic filter
We test the inhibitor in the heating water and top it up where it is low, as it slows the corrosion that turns into black sludge. If there is a magnetic filter, we clean out what it has caught.
Radiators bled and balanced
Radiators holding air are bled, and the system is balanced so the ones nearest the boiler do not take all the heat while rooms at the far end stay cool.
Your maintenance visit in three steps.
-
Step 1: Phone call
Tell us about the property, the kind of boiler you have and anything you have noticed, such as the pressure dropping or radiators that stay cold at the bottom.
-
Step 2: The visit
We go through the plumbing first, then the heating, working round the house rather than only looking at the boiler.
-
Step 3: Feedback
You get a plain account of what we found, what was done on the visit and anything worth keeping an eye on.
The price depends on the size of the property and the system, so we give it to you before anything is booked. The quotation is free, with no obligation.
