removal of foreign object from spa plumbing

Recommended Posts

Hello all,

I have a Viking Legend spa.  One (1 of 4) of the water intake grates near the bottom was accidentally broken, and a small piece of plastic from the housing was sucked into the intake pipe.  The piece is no more than an inch long and a couple cm's wide.  I didn't immediately realize it, so the spa and pumps were run afterward.  However, it doesn't appear to have affected the spa adversely - the pumps seem to run normally, and I don't hear any rattling or out of the ordinary noises.  My obvious concern is the plastic piece entering one of the pumps.  So - does anyone have recommendations on what step(s) to take next?  For example, should I drain the spa and try to push it back out by refilling through the skimmer?  Also, does the pump have a screen or some type of filter that further protects it from debris?  Suggestions welcome, and thanks in advance.

Jay

I think I might leave it be. 

I think to remove it you'd have to rig up a garden hose or water supply somehow to flush it out backwards.

Go under your spa and see where the pipe from that drain leads.  It may go to a pump, to a "T", to the bottom of the filter housing, to the heater or who knows where. I've pulled the metal faces from mini-jets out of pumps, BIC cigarette lighters (chewed up), small pebbles and plastic army men.  I've seen a few impellers broken by items that lodged in, and a few that still worked find, although a bit chewed up.  The plastic grating on the drain covers will loose a fight if put up against a jet pump impeller.  A circ-pump impeller might be a little more likely to be damaged, the the 3/4" fittings have even smaller interior dimensions and I doubt they could pass a piece of plastic an inch long and 2 CM wide.

Thanks, Cusser.  That was my thought as well, but my main concern was protecting the pumps.  I didn't know if a piece that small could get into either of them, or if it would cause any damage.  So far, no issues.  Do you know if there a screen of some sort that protects the intake directly into the pump?

Thanks, ScubaDave.  So far, I've had no issues.  It really is a small piece that doesn't appear to have had any negative effect, so I'm inclined to leave it be until I drain and refill the spa in a few months.  I did try to visually trace the line, but because of foam insulation, I wasn't able to trace with any certainty so I couldn't tell exactly where it comes from and where it goes.  I would assume the pump has a screen of some sort that protects it from small debris and foreign objects.  Is this the case?

No screen in a pump.  But I don't think you're going to have a problem.  Impellers are hard plastic and drain grates are thin and slim.  An impeller will win that fight.
