Common Problems

#1. No water coming out although the tap was opened

This is not usually what happened, but if there is no water coming out, then you should go check your pipe valves and water inlet filter.

The power valves could be shut off earlier. Besides, the filter could also be clogged by dust or unusual stuff from the water supply.

#2. Water stays cold

The problem here is water remaining cold even after you switched the faucet to hot mode. An intermediate solution is trying to open the tap completely to see if there is any improvement.

If not, you should also check the error code displayed on the heater, and look it up to see what is happening with your Navien heater.

#3. Water is not hot enough

In case water took forever to warm up, you could see if you accidentally set the heater at low temperature or not.

One other possibility is that there is a problem with your recirculation mode. In this case, you’d better have a contractor come to check the heater for you!

#4. Water is too hot

Generally, this happens because users have set the temperature too high. Try lower temperatures; it also benefits your electricity bill!

#5. Other minor problems

For any other strange, unusual or potentially dangerous, you’d better shut water heater off, then call for help from the technical support.

How To Replace And Install A Kitchen Faucet By Consumer Reports

Removing an old kitchen faucet is one of the most challenging processes when trying to replace them. You should always expect it to spell troubles at some point in time – poor access to fittings, hard-to-reach nuts, corroded pipes, just to mention a few. Otherwise, how to install a kitchen faucet would not be an easy, hassle-free task.

More so, installing a new faucet will only require you to follow the instructions in the included manual to get the job done. In the absence of unforeseen issues, you could be done in a couple of hours.

Therefore, this article provides all the necessary replacement steps and how to handle most challenges often experienced when replacing a kitchen faucet. Thus, ensuring you are done and washing up under your faucet.

How to replace a kitchen faucet

Tools needed:

Here are the basic tools you’ll find handy when replacing and installing a kitchen faucet:

Basic wrench, flashlight, new faucet, rags, bowls/Tupperware, new supply lines (provided it does not come with the new faucet), work light or camping lantern, and a putty knife.

Note: the basic wrench with a long handle is the most helpful in this process.

Where do you start from?

Before purchasing a new kitchen faucet, examine your old faucet and determine how difficult working on this one will be. Also, poke your head under your unit and with the aid of flashlight size up the sink underside to have an idea of what you are dealing with.

Obviously, the most imperative process of installing a new faucet is loosening the old nuts holding the unit in place. If those nuts are corroded, then you should assume that loosening them will be challenging. Here’s where you find a long-handle basin handy in budging them.

Also, do not forget to have a stock of your faucet. If you are heading to a home-improvement or hardware store, then take a picture of your basin and faucet to show the salesperson. He/she will provide you with a faucet that will work correctly with your existing sink.

While most new faucet comes with an already-connected new supply line, it’s advised that you know the dimensions of your supply lines. In my opinion, it’s not a good idea to reuse your existing supply lines. The best option is replacing the old ones with new ones.

In case your new faucet does not come with new supply lines connected to it; then you should consider purchasing new ones, and measuring your old ones ahead of time will save you from stress.

Step-by-step guide for replacing a faucet

Before starting with anything, the first thing to do is to read the instructions carefully and thoroughly. Next, ensure that everything under the sink is cleared out and cleaned, and get 1 – 2 good-sized Tupperware or bowls to avoid water dripping all over the place. Also, you’ll need rags to be safe when disconnecting supply lines.

Most importantly, turn off the shut-off valves before loosening the existing nuts or removing the old faucets. Further, the workspace needs to be well lit, and, as such, have work light or camping lantern handy under the sink. Well-lit workspace makes replacing and installing a kitchen faucet easier and less messy.

Step 1 – unhinge the nuts of the existing faucet using the basin wrench. You can also use a putty knife to break your faucet free. Be careful and patient, so you don’t end up scratching your sink.

Step 2 – follow the instructions provided by the manufacturer to install your new kitchen faucet.

Step 3 – use the basin wrench to tighten the nuts. However, ensure you don’t make the nuts too tight to avoid dealing with plumbing issues down the line. Most people often tend to twist too hard t make the nuts tighter, thinking it for better sadly, it’s always counterproductive.

Step 4 – After you are done with fitting all parts together, wipe down all the pipes and tubes under the sink with a rag. Once you’re sure they are dried, turn on the shut-off valve and allow the water to run full blast. Experts also suggest that you remove the aerator from the head of the faucet to allow sediment accumulated in your pipe flushed out. After a while, replace the aerator (don’t forget to turn the water off).
