Product Description:
The Pool Filter MPV Top & O Ring Quality Original MK1 is a replacement multi port valve top designed for standard swimming pool sand filter systems. The MPV top is the control section of the sand filter valve and allows the user to select different filtration and maintenance functions.
A multi port valve is one of the most important control points on a pool filtration system. It directs water either through the sand filter, out to waste, through a rinse cycle, through a backwash cycle, around the filter bed, or into a closed position when the system is not being operated.
This Quality Original MK1 MPV top is supplied with an O ring and is made from white plastic. The supplied dimensions are 155 x 155 x 155mm. It is designed to fit most standard swimming pool sand filters and is commonly suited to selected Quality, Aqua Max and Eartheco style filter systems where the valve type and sizing match.
The valve positions allow the pool owner or technician to control how water moves through the filtration system. The Filter position is used for normal daily filtration. The Backwash position reverses water flow through the sand bed to flush out trapped dirt. The Rinse position is used after backwashing to settle the sand bed and flush remaining dirty water to waste before returning to normal filtration.
The Waste position sends water directly out through the waste line, bypassing the filter sand bed. This can be useful when vacuuming heavy dirt or lowering the pool water level. The Bypass or Circulation setting allows water to move without passing through the sand bed. The Closed position shuts the valve, but the pump must not be operated while the valve is closed.
This replacement MPV top is useful when the existing valve top is cracked, stiff, leaking, difficult to turn, missing its handle, not sealing properly, or no longer selecting positions correctly. It can help restore normal filter operation when the rest of the valve body and filter setup are still in good condition.
Before purchase, always compare the old MPV top with this replacement part. Check the valve type, top size, bolt pattern, O ring seat, handle layout and filter model. Incorrect valve tops can cause leaks, poor sealing or incorrect water routing.
FAQs
What is an MPV top on a pool filter?
An MPV top is the upper control section of a multi port valve. It allows you to choose the operating position of the pool sand filter, such as filter, backwash, rinse, waste, circulation or closed.
What does this Quality Original MK1 MPV top include?
The supplied product information states that this replacement part includes the MPV top and O ring.
What material is the MPV top made from?
The supplied product information lists the material as plastic.
What colour is this MPV top?

What are the dimensions?
The supplied dimensions are 155 x 155 x 155mm.
Which pool filters does this MPV top fit?
It is designed for most standard swimming pool sand filters and selected Quality, Aqua Max and Eartheco models where the MK1 valve type and fitting match. Always compare with the existing valve before purchase.
What does the filter position do?
The filter position is used for normal daily filtration. Water is pushed through the filter sand bed, where dirt and sediment are trapped before cleaner water returns to the pool.
What does the backwash position do?
Backwash reverses water flow through the sand bed to loosen and remove trapped dirt. Dirty water is sent out through the waste line.
What does the rinse position do?
Rinse is used after backwashing. It settles the sand bed and sends remaining dirty water to waste before the system is returned to filter mode.
What does the waste position do?
Waste sends pool water directly out through the waste line without filtering it through the sand bed. It is useful when vacuuming heavy debris to waste or lowering pool water level.
What does the bypass or circulation position do?
Bypass or circulation allows water to move through the valve without passing through the sand bed. This can be useful in specific maintenance situations or when directed by a pool professional.
What does the closed position do?
The closed position shuts off the valve. The pump must not be operated in this position, as it can create pressure and damage the system.
Can I move the handle while the pump is running?
No. Always switch the pump off before changing valve positions. Moving the MPV handle while the pump is running can damage the valve, gasket or internal parts.
When should this MPV top be replaced?
Replace the MPV top when it is cracked, leaking, stiff, difficult to turn, not sealing properly, has a damaged handle, or does not select filter positions correctly.
