What does my pool diverter valve control?

What Does My Valve Control?

Good question; strike that, great question!  This topic is brought up quite often by puzzled pool owners presented with a rat’s nest of pipes, elbows, valves and pumps. The state of some pool plumbing systems makes you wonder if they charged by the hour or by the pipe. The maze of PVC and excessive valves causes an issue when attempting to find the source or outlet of water flow.

Another common reason we have trouble identifying a pool diverter valve’s function is the label may have bleached out or fallen off. These are natural occurrences that we normally do not think about until we are squinting to read faded print on a baked label. But we are here today to let you know a little trick on identifying the function of your valve in both of these cases. (more…)

Bubbles coming out of my pool return line

Why Do I Keep Getting Bubbles In My Jets?

Everybody loves a bubble bath, show me a person who doesn’t and I’ll show you a liar. Bubbles are fun but for pool owners bubbles represent a time for panic. For us, bubbles are no longer the sign of fun in the sun and frolicking, they are a harbinger of doom. Ok, that was a little excessive but you get the point. A stream of bubbles is a sign of the unwanted presence of air within our pool’s plumbing system. This air is likely the cause of a sucking air leak from a pump, union or diverter gasket. The leaks and the air pockets they form will lower water pressure and greatly decrease the capacity of our filter system. (more…)

Parts of a Pool Pump

Identifying Major Pump Parts and Their Functions

A person who has had the pleasure of seeing the innards of a pump (opened by their own hand or glancing over the shoulder of a technician) may have noticed it looks simpler than expected. After all, the pump is this piece of machinery that can pump 80 gallons or more a minute, leaving one to expect a few bells and whistles hidden away inside the casing. But in practice the pool pump can be broken down into two categories of parts; the drivetrain and the outer structure. Or put simpler, the parts that push and pull the water and the ones that keep it from leaking. (more…)

V-Thread, Buttress, and Clamp Style Valve

What Is a V-Thread, Buttress, or Clamp Valve?

Without checking, what thread type is on your sand filter valve? Not a clue? Do not worry, you are not the only one.

The connecting joint of a multiport valve is an afterthought to most pool owners; likely there are more pressing matters, water chemistry, air leaks and the like. The only time we notice the thread type is the third time we try screwing on a new replacement valve. That is exactly when we see that the thread on the tank is a buttress but valve is a V-thread. That is $80 for the valve down the drain. not literally of course, because the drain is not working as a result of your filter is being out of commission. And that is where we come in.

The trickiest part is that only some filter tanks can use all three of these forms.  It depends on certain factors i.e. model, year, or specific type. For example the Pentair Tagelus uses all three. (more…)
