Spread the love

It is quite often that toilet cisterns start to malfunction and so you would be required to replace them with a new spare piece and this is where fluid master spares come in handy.

Many people who buy toilet spares are quite reluctant to call a professional to get the job done, simply because of the cost it incurs and rightly so, why hire a professional when you can do the job all by yourself.

Below we are going to list the process of installing a toilet cistern inlet step by step to help you install it like a professional.

But first… 

You are going to need some equipment to carry on the task at hand. The tools you will need are

  • pair of grips
  • screwdrivers

1.Check the cistern

First you would need to check the cistern you are required to replace. It would be either bottom entry or the side. In this case it is the bottom entry but that still does not matter as the steps would be the same. Open the head of the toilet and check the cistern and but the right product

2.Find the pipe coming out of the bottom

When you check inside you would find a fill pipe coming from the bottom with a float around it.

3.Turn of the water supply

This is a fairly easy task as all you have to do is turn of the water supply from the isolating valve or you may need to find the stopcock to completely halt the water supply that is in case you don’t have an isolation valve in your water connection.

4.Dry out the tank

You would need to dry out the tank by flushing out the water from it again and again until no water remains. Also you must check the valve or the stopcock to check that the tank is not filling again.

5.Disconnect the pipe

Now that you are sure that no water is coming through the pipe and the tank is dried out now you can disconnect the water supply from the fill valve below the cistern. Now take the grips and loosen the nut on the isolating valve, it will release some water as some would remain in it so you don’t have to worry about that much.

6.Remove the old fill and take out it

Now you can remove the old fill by removing the plastic back nut and then take it out as it will come out without any resistance. Duly remove all the old rubbers washers which might stick, clean the hole so that the new fill can be placed easily

7.Place the new fill valve

You can now bring in the new fill valve from Fluidmaster spares and place it in your toilet cistern. If you think that the height is an issue of the fill then don’t worry as you can adjust the height after you place it in the cistern. Once you have fixed the height of the fill valve you can lock it so that the height is locked.

8.Place it and lock it

With care you must first take out the back nut and then place it in the cistern. Once placed with its rubber washers it will provide a water tight fit. After that you can place the back nut on the threaded brass shank and move it clockwise to completely tighten it.

 Make sure the cone washer is in center and then tuck the back nut to complete putting the fill valve in.

9.Connect the fill valve to isolation valve

Now you can connect the fill valve with the isolation valve to continue the water supply to the cistern. Once you have connected it run the water supply to check if any joint is leaking or not. Flush the toilet down to check the fill valve is functioning properly. Once you are satisfied you can now close the lid of the cistern.
