New bathroom and the bath tap runs cold

BuggerFlip · 17.01.2018 11:23

Hello,

I recently had my bathroom renovated. It was quite a bit of work as the bathroom was gutted and everything replaced, the position of the bath moved etc to accommodate a large walk in shower. It took a long 4 weeks from the 2 types recommended by the bathroom store. Overall I’m happy with their work, but we had a bit of a fight when I suggested they work longer to finish the bathroom. That was the week before Christmas and the 2 1/2 week job went into its 4th week. We couldn’t put up the Christmas tree because the living room housed the bathroom and there was dust everywhere. For comparison, the toilet people came at 9.20am and worked for about an hour, then went to breakfast at 10.30am to 12pm and then finished at 3am. When they took the job, there was no mention of their 4-hour day. All I asked was that they try to finish the work by the end of the week as the children were keen to put up the Christmas tree and suggested that they have breakfast before starting work for the day – that didn’t turn out to be the case good on!

Anyway, to get to the point. The bath was only used a few weeks ago and with just the hot tap running (through the mixer spout) it runs hot, then freezing cold, then a little hot and then a little stone cold. It’s almost impossible to run a bath at a decent temperature. I checked the boiler and it shows an error code of U9 which I think just means the temp is 109. Before the bathroom renovation, the bathroom hot water tap was fine and we had no problems at all. I reluctantly contacted the plumbers and was told it was a problem with my boiler. Would you agree that it is your responsibility to ensure the bath produces hot water consistently, wouldn’t you? Having spent over £6,000 just on the installation I’m quite upset that the bathroom isn’t working as it should. There are no further problems with another tap in the house or central heating from this combi boiler. Any advice on how I should go about this with plumbers?

Reasons Why Your Hot Water Just Went Cold

Depending on the design of your heating system, whether you have an ‘open vented’ system or a ‘sealed system’, the cause of the fault can vary and we strongly recommend that you have a competent technician carry out the check.

Below we have a list of common mistakes that might help troubleshoot or identify what might be affecting your hot water

Airlocks (open vented system)

An airlock is a situation where air gets trapped in the system, blocking the hot water on its way to your faucets or shower heads. An airlock can partially or completely prevent hot water from flowing out of a faucet.

The best way to remove an airlock is to use tap water pressure from your kitchen sink mixer and follow these 3 easy steps.

1 – Use your palm to block the spout of your kitchen sink faucet

2 – Open the hot water tap

3 – Open the cold water tap

The cold water now flows into the hot water system and uses the pressure to remove the airlock. Do this test for between 3 and 5 minutes, then release your hand and turn off the cold water faucet. If you succeed, the hot water will start to flow

However, if the issue has not been resolved, we recommend calling an expert as your system may have underlined plumbing issues.

Low water pressure

We get many calls each week about hot water issues and low water pressure. Both are associated with the same error and both can be easily fixed. If your boiler shows 0 on the pressure gauge and you have no hot water, 9 times out of 10 you just need to increase the pressure of the central heating system to 1 to 2 bar, this can be done by opening the filling circuit under your boiler or on your cylinder.

Changeover valves, pumps 2-way and 3-way valves (open vent and sealed systems)

These are both common combi boiler failures and usually progress to a failure for the same reasons, sludge or a PCB failure, you will need to contact your local expert to test this.

Due to lack of maintenance and treatment, sludge builds up in your heating system. Your central heating system should be drained, refilled and refilled with a central heating inhibitor that will prevent the corrosion process in your heating system. Otherwise sludge will accumulate which can block your diverter valve, 2-way, 3-way valve and central heating pump.

You can do a manual test with your hands at home to see if any of these components are faulty. We do not recommend touching or disassembling these components, nor should you place your hands on electrical cords.

To test the diverter valve on a combi boiler, you can simply turn off your central heating, leave the hot water tap running from an outlet, and place your hand on the supply pipe coming out of the boiler (usually the leftmost pipe). If that gets hot while the faucet is running, then you know your diverter valve is closed in the wrong position.

The same rule applies to 2-way and 3-way valves, if you request hot water or central heating but the valve lever does not move, you can hear the motor is stuck or the water is flowing through the wrong pipe or not all , then you know your valves may need replacing.

Pumps can be tested by a compliant person at home by removing the pump’s center eyelet with a flathead screwdriver and then inserting a smaller screwdriver into the center. If the pump stops easily or does not move at all, it needs to be replaced.

If a pump feels hotter than usual, this is also a sign that the pump is having trouble turning. Always consult an expert to properly check your pump.

Other causes that you cannot test

Fans, gas valves, NTCs, flow switches, circuit boards, defective flues, flame measuring electrodes, spark electrodes… the list goes on. Boilers are complex machines and there are many components of a central heating system that can cause problems with your hot water and therefore it takes an experienced heating engineer to work on them.

Intermittent hot water or you want to know more? Get help from the experts

If you’ve noticed this keeps happening, it’s a good idea to call in a gas safety technician to try and diagnose the problem. Trying to guess for yourself what’s wrong with your cauldron can do more harm than good. The information provided above is intended as a guide to diagnosing simple faults. We always advise that you call your local expert to have your boiler professionally diagnosed.

So if you are having any issues with your combi boiler, closed system boiler or open flue system boiler then give us a call on 0208 323 5678 and our fast response team can advise on the best course of action.

10 Reasons Why the Water in Your Bathroom is Ice Cold

Are you afraid to take a shower every morning for fear of being splashed with ice cold water?

While it’s an effective way to wake up quickly, most people would opt for coffee instead.

It’s definitely not pleasant.

And it’s not a situation you want to face all the time. So what could possibly be causing this cold-water dilemma?

We look at ten possibilities.

1. Pressure relief valve failure

You probably don’t think about it much, but your shower faucet has pressure balancing valves that not only regulate the pressure, but also control the ratio of cold and hot water coming out of the shower head.

Corrosion and mineral deposits in the valve cartridge can cause the valve to stop working.

While the solution is fairly simple, you need to be comfortable disassembling the faucet and removing the cartridge to replace it. If DIY plumbing isn’t your thing, call a plumber.

2. Sanitary problem behind the wall

Do you have an older house?

It’s entirely possible that behind the wall you have old-fashioned plumbing with cross-connected pipes that perform the same function as those new-fangled showerheads. And something went wrong.

Unfortunately, this is NOT an easy fix and you’ll need to call in the professionals for it.

3. Indicator light

If you’re only getting cold water, the problem could be with your water heater.

For a gas water heater, check that the indicator light has not gone out. Without a pilot light, the gas that heats the water in the tank cannot be ignited.

If the light is off, follow the instructions for your model to light it back up. While newer water heaters have igniters, older ones may require a match.

Once the indicator light comes back on, everything should be fine again. However, if it refuses to stay lit, then look for a possible problem with the thermocouple.

This safety device prevents the gas from escaping from your heater unless it is being burned. And the replacement is definitely not a repair that you should do yourself.

4. Faulty heating elements

On the other hand, if you have an electric water heater, you could have a problem with the heating elements.

Electric water heaters have a heating element at the top and bottom of the tank. There is a thermostat for each element.

In general, the top element controls the bottom one. If the upper element thermostat is broken, you will only have cold water. If it’s the bottom one, you’ll have some hot water. But just enough to annoy you.

5. Too much draft on the water heater

How many people are in your house?

If one family member is doing laundry while another has just turned on the dishwasher after breakfast, chances are your water heater isn’t right for your shower either.

Every water heater has a maximum capacity of hot water that it can hold in its tank. And when that’s gone, it can take half an hour or more for the new water to heat up again.

The only true fix is ​​to get a larger capacity water heater. Or create a rigid schedule of when and what water can be used for. But who has time for that?

6. Hard water

Hard water is full of minerals. This is great for a breakfast cereal. Not so good for your faucet.

Water with a high mineral content tends to leave behind some of these mineral deposits as it flows through your faucets.

And because higher temperatures encourage the kind of reactions that cause these deposits, the hot water side becomes clogged more than the cold water side.

This will likely be something you notice gradually rather than suddenly. You may want to call your plumber to make sure this is the case and then see what he or she recommends.

7. Airlocks in pipes

If water is bubbling out of the hot water faucet, most likely there is a problem with air in the water line.

It is not uncommon for air to become trapped in water pipes. And because it’s less dense than water, it gets stuck at high points in the pipes.

This is called an airlock and can result in a partial or even complete water blockage.

8. A leak in the hot water tank

Have you noticed water around your hot water tank?

Before you go into panic mode it could just be condensation on the boiler. Once the tank has heated up, it disappears.

However, if the tank is hot and you still see water, you could have a real leak.

Often a leak is the result of an old water heater making its way out. And a water heater that’s far past its prime might not do as good a job of heating your water. If that’s the case, you’ll need to replace it.

But if you have a newer tank then something else could be going on. Best to call a plumber.

9. Frozen pipes

During particularly long and cold periods in winter, there is a risk that your water pipes will freeze. The pipes most likely to freeze are the ones closest to an outside wall. That’s why it’s a good idea to keep cabinet doors under the kitchen or bathroom sink open if they’re on exterior walls.

You can use a heat lamp, space heater, or hair dryer to thaw the tube. Or buy a thermostat controlled heating tape and wrap the affected part of the pipe.

If these solutions don’t fix the problem, contact a plumber. A frozen pipe threatens to burst.

10. Set the temperature on the water heater

Is your water heater set to the right temperature?

Most water heater manufacturers consider 120 degrees to be the optimal temperature to set your thermostat.

If your water is consistently cold, you may need to increase the temperature. Just keep in mind that if you turn it up too high, you could end up with a scalding hot shower instead of a freezing cold one.

And that could be worse.

You don’t have to settle for freezing cold showers!

Nobody should have to wake up to the shock of ice cold water every morning.

So when the water in your bathroom is getting cold, it’s time to do something about it. Contact us today so we can help you resolve the issue.

Then take a hot shower again.
