View Full Version : Pegasus Problem

12-01-2009, 08:01 AM
Hi Guys,
I have a curious problem with a Pegasus shower only single handle unit that I installed for an outdoor shower (read "set in stone (well stucco)"). For the past two years the unit has worked perfectly. Last month the cold water just stopped. I have removed the cartridge and only hot flows- no cold. The flow stops are full open. I even tried blowing air into the cold line from the cold flow hole (with nearby hose bib full open) and nothing...

There is a large (1" or so) bolt head on the cold side of the unit that I haven't messed with yet.. it looks like it must be an adjustment access hole cover or ? .. maybe something there..

any suggestions or ideas??

Sounds like a balance spool, which is stuck. Call Peg/GB for parts.

Balance spool? Would that be what is hiding behind the large bolt head perhaps? I'll go take a look...
Well, this is what I found..

The cold flows fine with the cap removed.

I cleaned out some crud from the top and sides of the insert and the cap, but the insert wont budge. Is there a way to remove it? Is this the mysterious Balance Spool that you've mentioned?

If it DID NOT come out when you removed the cap, it is broken. You have to get a new balance spool, (it is one piece and attached to the "cap"). Then extract that piece from the valve before installing the new one.

Thank you. I must say you have been much more helpful than the guys at my local Home Depot... they just have no idea. And the old plumber there that I spoke with today said (while on duty and in uniform mind you) that I should "not have bought Pegasus because it is crap!"

Live and learn...

I'll fish out the broken spool and replace it with a new one if I can find it. If not, I'll open up the wall and install a Moen.
