Radiator Repairs

Business radiator problems come in various shapes and sizes. Thermostatic valves can stick, joints can leak, tiny pin holes can squirt a fine jet of water across the room, or the radiator can stop heating up. For hotels, pubs, shops and other businesses, a chilly environment will deter customers. No1PHD plumbers can diagnose faults and repair every kind of radiator, quickly and without fuss. We specialize in all commercial environments and business premises so we have the knowledge and experience to solve your plumbing, heating and drainage problems fast and effectively.

Stuck valves

As winter sets in, businesses turn on radiators that have probably been turned off for months. It’s then that owners and managers are faced with stuck valves. Conversely, a customer may complain about excess heat, and the business owner finds the radiator is stuck on its maximum setting. This frequently means disruptive room changes in hotels for example.

Many radiator valves today are thermostatic – you can turn a valve, which has a numbered scale, to adjust how much heat the radiator is producing. Business owners often try to unstick the valve themselves by getting pliers and using force to try and turn it. This frequently fails to work, and sometimes ends up destroying the working parts of the valve – not what you want.

There’s also the “hit it with a hammer” school of thought, which has similar potential for damage. Spraying the area with a lubricant may help, but not if the problem is inside the valve, and the lubricant isn’t reaching it.

Our professional plumbing team knows exactly which bit of the pipework to unscrew, and has specialised tools for tackling every kind of radiator. Years of experience mean that our plumbers know exactly how much pressure to apply, to avoid damaging the valve. And if it is already damaged by well-meant efforts to do the job yourself, the plumber can replace the valve.

Leaking joints

A leaking joint can rapidly damage a hotel or pub carpet, or stain a bar’s stripped wooden floor. Joints can be difficult to access, and again, hard to budge. For a permanent solution, get the leak repaired by a plumber with the correct tools. Our plumbers can quickly fix a problem that you may have been struggling with. We’ll repair the radiator if possible, but if not, we can quickly install a replacement radiator.

Pinhole leaks

Guests or patrons can be puzzled to find a pool of water on the floor some distance from a radiator. The problem can be caused by a tiny hole in the radiator. Because the water is under pressure, a fine jet of water can travel across the room, pooling a couple of feet from the radiator.

When the leak is found, it looks as though it will be easy to fix. Some businesses try using one of the mastic leak stoppers that supposedly work underwater. However, in practice, these are complicated to prepare and apply, and when the water is under pressure, it finds its way around or through the mastic before the mastic can harden and plug the hole.

After noticing that the house was unusually cold, we found that the heating wasn’t coming on and that our hot water had also failed. We called the team at No 1 PHD who dispatched an engineer to investigate. After discovering that the culprit was a faulty boiler part, they ordered in a new part and got it fitted as quickly as possible. The guys were great, and we couldn’t be happier.

For days, we’ve noticed a foul smell coming from outside and a gurgling sound coming from one of the drains. Whenever it would rain, the area around it would flood slightly and take ages to drain. We tried buying drain unblockers, but none seemed effective. Eventually, we turned to No 1 PHD and were left wondering why we didn’t do this sooner.
