Product details

This is the Waterway replacement volute face plate housing for the 3/4 HP booster pump, carried as part number 315-8300 and also listed as 315-8300B. It is the front housing that the impeller turns inside and that carries the suction and discharge connections.

When to replace it

A booster volute housing is normally changed rather than repaired. A crack around a port, damage from water left in the pump over a freeze, or the erosion that follows running the pump dry all leave a housing that will not hold a seal no matter how many gaskets go into it.

While you are in there

The volute o-ring is a separate part. Replace it at the same time, because a new housing sealed against a compressed old ring will find a way to weep.

Questions and answers

What people ask about this product, answered by our pool techs.

Is 315-8300 the same as 315-8300B?
Our records carry both numbers for this housing. If the number stamped on your pump is one or the other, this is the part; confirm the suffix against your pump if you need an exact match.
Which pump does it fit?
It is listed with the Waterway 3/4 HP booster pump parts.
Does the o-ring come with it?
No. The volute o-ring is a separate item and should be replaced at the same time.
Why would this housing need replacing?
A cracked port, a housing damaged by freezing, or a pump that has been run dry are the common reasons a booster volute housing is changed rather than resealed.
