spa spillover to pool

Posted by Dennis Gunter on April 18, 2012 at 7:51am

Have a spa installed higher than a pool with one system....the spa overflows into a resevoir and then thru an equalizing line to the pool.....the difficulty is the equalizing line is too small 1 1/2" and the resevoir overflows...there has been a suggestion to do a water exchange at the equipment; I know you can do with 2 systems .... can you do the water exchange from pool to spa at the equipment pad using one system?..the underground equalizing line is not big enough and leafs are jamming it up and the overflow at the bottom of the spa is filling up too fast...... like you, I don't want to dig up the expensive landscape and enlarge the line or add another line any advice thanks dg

    I like Len Payne's answer better than mine. For one, it is much simpler and fool proof.

    I would restrict the amount of water going from the pool to the hottub by a gate valve in the pool shed. By restricting the amount of pool water entering the tub, you should be able to equalize the flow to make a bad situation a little better.

    I never install a spa on the same equipment as the pool unless the spa can directly spill into the pool.  I have just seen too many problems with this particular application and have seen pools drained and popped due to this type of installation.   I don't recommend equalizing lines for spillover or motorized valves.  My suggestion is to put them on separate systems but that may not be possible because of equipment area size, gas/electric sizing, etc.

    An automated Jandy Valve wouldn't be sufficient?

    Is there a way to eliminate the resevoir and simply add a spring Valve or check valve with an air locking system near the equipment pad so no water can be lost out of the spa?  I don't get why the spa water doesn't just spill in the pool if the equipment is the same.

    If it has automation, disable the routine spillover feature. Run the pool for its normal time, then switch over to filter the spa for an hour or so. Then have it do a spa spillover for a few minutes to replace any water in the spa lost when the valves were switching (to minimize this, have the valves turn while the pump is on). Set up this spill over to run a short time so that it doesn't have time to over flow the basin. 

    Admittedly, this is not optimal, but it might work.
