I usually just cut out the bad sections of plastic line and splice in new ones. Plastic tubing you can get at Lowe's 1/4 and 5/16 diam. tubing is needed and they have 1/4 inch brass compression couplings but NO 5/16 You can get 5/16 couplings on this site part # WR2X8545 and they may have 1/4 inch brass compression couplings.

Hello,

I was wondering if you ended up splicing in a new section or replaced the actual tubing and water tank? If so how much work or problems did you incur while replacing the water tank?


Thanks,

Thanks for the quick reply. I did just that a couple of weeks ago. However, this is the 5th time the line has cracked and broken due to the heat. The last 5 times the various repairmen have just cut the bad tubing off and replaced/spliced with new tubing.

So, the most recent time I was at my mother-in-law's and was able to repair the line myself. While doing so, it is quite clear that this will be the last time the tubing can be fixed without replacing the whole water tank line. With each repair the line has become shorter and shorter to the point it is pretty much kinked right now where the tubing enters the right side on its way up to the water filter.

Quite a poor and sad design to say the least. Who designs plastic tubing to be so close to a heat source?

Thanks again!
