    Attached Spa drain not working??

    Hi all. I have an attached spa that suddenly doesn't work! For some reason, when I switch my valves to the spa setting (spa in and spa out) I get an insufficient amount of water moving into the pump (and then I have to turn it off). When I move the setting back to draw water from the pool, it works again. Any ideas?

    Is it sucking air into the pump basket?
    If so it's a suction side air leak in the spa line.
    If it isn't sucking in a lot of air then it's probably a spa suction clog.

    Are these manual valves you turn by hand, or are they run by a controller?

    The valve is manual. I think it is sucking air. When I look in the strainer basket, There is a small stream of water coming in.

    If it's clogged or partially blocked how would I un-clog it?

    Make sure the valve is set to draw from the spa, then open the pump strainer and stuff a garden hose wrapped in a rag or a drain king in the pump inlet pipe and let 'er rip. If there's mud or whatever plugging the pipe, it should blow it out through the spa drain.

    Thanks! I will give that a try. I assume that if the problem is a leak on the suction side, I might see the water exiting as well? Strange thing is - the spa has worked fine since I opened it in May. Just developed this problem this week for some reason. Since no-one has been digging; and it's been 85+ outside, I don't know how a leak would develop.

    O-rings and seals can develop a leak just through use. Also you can have an air leak and it not leak any water.

    Ok - So I mucking around with it this morning, and it starts to suck in air on the pool intake side too. I decided it could be the jandy valve leaking. Turned the hose on and ran it over the valve - and the problem started going away. While I had the thing open, I decided to stick the drain king into the spa intake side. I've never used one of these before. Anyway, I noticed a "hissing" sound around the area where the intake pvc pipe joint is. Some water also coming up into the spa. No sign of a clog. Re-assembled the Jandy and ran the pool. 100% water coming into the strainer basket. Like new! Turned it to spa - not bad - not great. Some air is definitely coming in. I am pretty confident that it is the joint in the pvc on the intake side. The way this thing is plumbed, it will be a big time pain in the ***** to cut and replace. Any suggestions on "sealing" it for the time-being?

    Post a picture of it and we should be able to come up with something that will work as least temporarily.

    You might try wrapping it with electrical tape if you can to see if it really is your problem.
