How Can You Fit the Ball Valves In Your Cold Water Tank?by Jessica W. Writer
Water flow has to be controlled in the cold water tanks, and the ball valves have a responsible role with regard to proper fittings.
A ball valve is defined as the type of quarter-turn valve having a hollow ball for controlling flow through it. The valve's 90-degrees turn positions the ball's hole in line with the flow direction, while the reverse completely shuts off the valve in the closed position. The attached stem at the ball's top extending outwards through the seal of the stem connects to a manual handle or else to a pneumatic or electric calculator. Often, the ball valves are used for ON/OFF operation, while these even operate as the flow regulating valve.
The ball valves are meant for controlling the water level in the cold water tank. If somehow, they stop their correct working procedure, then water will be dripping or flowing from the tank's overflow pipe. In this guide, we have pointed out how to fit a new ball valve.
Step 1 – Turning Off Water
The water at the mains should be turned off for starting.
Step 2 – Unscrewing the Feed Pipe
Make sure to wear knee pads, protective gloves, goggles and a dust mask. Avoid fiberglass insulation since it causes respiratory and skin irritations. Avoid disturbing the insulation as much as you can. Lay a Medium Density Fibreboard of MDF board or else anything similar over your attic insulation, so when you need to kneel down beside the cold water tank, then you can do it comfortably. Use an adjustable wrench and unscrew the feed pipe instantor fitting.
Step 3 – Detaching the Feed Pipe
Pulling the copper pipe away from the ball valve housing detaches the feed pipe.
Step 4 – Undoing the Retaining Nut
To undo the retaining nut outside the water tank and remove the ball valve, pull the valve body from the water tank.
Step 5 – Inserting New Ball Valve
Ensure the ball is securely attached by inserting the new ball valve assembly and checking it. Pass the threaded valve housing assembly through the existing hole in the water tank and then tighten it into place with the very retaining nut.
Step 6 – Reattaching the Feed Pipe
Pushing the copper pipe, get it completed with its olive (the soft brass ring at the pipe's end) into the valve body and tighten the instantor well fittingly carefully and with great firmness. Maybe, the olive should be changed if it is showing damage signs. Next, thoroughly dry the fittings.
Step 7 – Checking for Leaks
At the mains, turn the water back on and check the new joint by holding a dry cloth directly under the newly tightened fitting, should there be any leaks. With the joint being tight and still some water escaping, then the olive is damaged and it should be replaced.
Ball valves contain three main types, namely standard port, full port and V-port for precise flow control. These are helpful at maintaining consistent performance even after many operation cycles have been passed, as well as sealing tightly, handling high pressure and requiring the least maintenance. The ball valve's simple mechanism along with its easy operation and flexibility deems them much more popular in industrial applications with 1000 bar pressures and 400°C temperature.
