Slide gate valves are used to control water pressure. Due to constant pressure of the water, there are possibilities of wear and tear of any part of the valve or the valve itself. It is recommended that they be checked properly to make sure that everything is fine and should be replaced at the earliest if there are any damages to make sure that there are no major problems.

Step 1: Turn off the Water Supply

Turn off the water supply from the main on both sides from the water meter. Place a bucket and a rag underneath the valve so that you can catch any water that might flow out.

Step 2: Loosen the Nut

Use an adjustable wrench to hold the valve housing firmly. Use an open-ended wrench to make the compression nut loose so that if there is any water pressure, all the water will leak out completely.

Step 3: Loosen the Bonnet

Take an adjustable wrench to remove the stem, which enters into the valve’s housing. If it is screwed then you need to make sure that the housing is held firmly with the wrench and using a proper sized open wrench, you need to turn the bonnet.

Step 4: Take out the Bonnet

Carefully take out the bonnet from the gate valve housing making sure that the disk comes out along with the bonnet from the housing.

Step 5: Replace the Valve

Replace the valve if there are any damaged seats, or clean the seats of the valve using a rag. Damage can include any chipped or broken edges or any sort of wear and tear of the disk.

Step 6: Replace the Disk Slot if Needed

Check the disk slot to see if there is any damage. If there is any damage then replace the disk slot by sliding the stem out from the slot.

Step 7:  Replace the Stem if Needed

If the stem does not turn properly or if it sticks then you can replace the stem. Some stems can be unscrewed from the bonnet.

Step 8: Reassemble the Gate Valve

The gate valve needs to be reassembled properly by sliding the bonnet along with the disk and stem into the housing. You need to make sure that while tightening it you do not apply too much pressure. If you notice this, then the valve is not sticking. Use an adjustable wrench to tighten the bonnet and the compression nut.

Step 9:- Check the Valve

Check the valve by turning the supply of water once again to make sure that everything is fine and that there are no leaks. If there is any leakage, turn the water supply off, fix the part that is leaking and check again until satisfied.
