According to the guide to grasses at Pawnee Butte Seeds, tall fescue is adapted to Arizona. They list creeping red and sheep fescue as not adapted, but those varieties take less water than tall fescue does. Tall fescue usually needs about 3/4 inch of water per week, but I think you'd probably need more than that in Phoenix due to the amount you'd lose to evaporation. I don't know which ones are most heat tolerant. One drawback to most fescues is that if some of the grass dies, it won't fill in (unlike bermuda, bluegrass, and others). Creeping red fescue will fill in, but I'm not sure there are varieties that are appropriate to Phoenix. You might try calling Pawnee Butte seeds. They're located in Colorado, but seem to be targeting most of the intermountain west, so they may be able to help. I would imagine there's an extension office in Phoenix (or somewhere in Maricopa county, anyway) that could give you some help.

I agree I really like the mixed fescue lawn we have in back (seed mix of red,tall,etc. varieties of fescue... similar to the turf rolls sold at our local Home Depot each year)& it feels SO cool to walk on in the heat of summer & stays green most of the winter & the top does not die back. But, I find it does require more upkeep (fertilizer, water) than the very fine bladed (feels like a soft green velvet rug!)some kind of Bermuda that came in some how from a neighbor's lawn that he seeded from a variety of Bermuda he can't now recall & has now taken over our front lawn. Love them both but the latter certainly is less needy, hardier, takes abuse .... and turns brown/top dies back in winter & comes up from the roots in spring. I have to power-rake the dead top layers early in the spring every year or so before it begins to grow up again from the roots. I live in zone 7 @ mile high Albuquerque, NM & the minus 9 we got this past winter (& minus 19 back in the 1970's!)hasn't kept the Bermuda from forming a pretty front lawn again this summer... it loves the heat & we have had NO rain at all all year here in our part of the City so only survives on weekly sprinkling for an hour & fertilizing once in the spring. Some of the varieties of fescue in the seed mix I got have broader leaves & tends to clump so has to be mowed well. A neighbor bought Zoysia plugs two years ago but has had little growth or spreading from them yet & is disappointed. Guess you will have to decide on either the year round green of fescue or hardy, summer green of Bermuda maybe!

About 6 hours later the same problem happens and the water is there again I can blow into that tube and hear bubbles, why is there so much water?????

I'm thinking your getting double pumping for a short time and the water is taking the path of least resistance. Also, the expansion point of the system should be on the suction side of the pump, a sealed expansion tank should be used instead of the open system. Makeup water is added at the expansion point too. Stay Warm!
