Question Running H2O from Filtration Drain Connection tube? GE PXRQ15F R/O system.

Hi all,

We used to have a G.E. PNRV18ZBB01 R/O system for about 7 years. We just upgraded to a PXRQ15F R/O system (Install manual: http://products.geappliances.com/Mar...e=49-50198.pdf). The other unit was functioning ok, the reason for the upgrade was that I was really tired of the crazy maintenance on that older system and wanted something easier to take care of, in addition to part of the base of the faucet casing being broken.

The problem we are having is that the black 3/8" inch Filtration Drain Connection tube has running water through it, even when the faucet is turned off. The installation directions were followed, and in our case we had to go with the 'Secondary' installation on page 16 on the manual (option D), for the filtration drain. This was the same set-up for our previous model which worked just fine w/o the noisey 'leak' sound into the secondary sink plumbing which ties into the primary sink/disposal plumbing.

Why would this new model drip water (really is more like a gentle continuous running water) from this Filtration Drain connection when the faucet isn't, or hasn't been in use for hours? This is occuring right after going through the sanitation process and installing the new filters. Perhaps it's because the refill tank isn't filled up yet? I've read elsewhere that there could be a worn out bladder (in the tank?), but that was on older units. This one was just purchased new last weekend and finished installing it today.

Any experieces one might be able to share, related to this would be greatly appreciated.

The tank must fill before the auto shut off will activate. Once the auto shut off stops water to the membrane, the drain will stop flowing. To check to insure the shut off works, turn the tank valve off (with the faucet closed). Within 5 minutes, the drain should stop.

Thumbs up

Thanks for the reply biermech!

Yes, after the tank had filled (went to bed before it was finished but estimate around 4 hours), the "Filtration Drain Connection tube" no longer had water running through it, and therefore no water draining noise coming from that sink. Apparently, this newer unit is different from the previous model in such a way that during the recharging (i.e. after replacing filters) process, there is significant water flowing through that drain tube. With the previous model, there was no draining noise as there must have been either no, or insignificant amounts of water draining through that pipe during recharging.

Anyway...thanks again.

Gary
