1 *the Public Works Department approached nine homes regarding 2 their water pressure, seven of which have had no complaints; 3 *his men were unable to get into the two homes where pressure 4 problems were indicated to ascertain whether the problems might be 5- internally caused by an older water softener or heater or a loose 6 valve; 7 *indicated the basis for these suspicions was the fact that the 8 homes next door did not have pressure irregularities. 9 The Public Works Director explained further that: 10 - *a pressure gauge had been installed the previous day on the 11 house at 3312 - 33rd Avenue N.E. which is one house away from 12 complainant's and after a full day of - monitoring the lowest pressure 13 registered all day was 38 pounds at 9:00 P.M. ; 14 *this booster system has three individual pumps which operate 15 in sequence in response to demand for pressure; 16 *the first pump pressure goes up to 90 pounds and down to 17 approximately 65 pounds when the second pump is activated. The 18 third pump maintains a constant pressure level and is activated when 19 the second pump pressure requires; 20 *some of the two story houses on Hilldale are bound to have • 21 problems on the second floor with 32 pound PSI pressure release on 22 32nd and Silver Lake Road, but if that happens, an automatic line 23 pressure valve, which connects with the regular water line system 24 opens up and that line system takes over; 25 *the survey shows that the system is working "very efficiently 26 and effectively" and in just the manner for which it was designed. 27 Most Problems Caused by Sprinkling 28 Mr. Hamer indicated the pressure is naturally going to go down all 29 over the City during sprinkling periods from 3 :00 P.M. to 11:00 P.M. 30 and the booster system in this area is no more able to keep up than 31 the elevated tower system which serves the rest of the City. The 32 only thing the City could do to prevent water - pressure going down 33 while people are sprinkling would be to ban sprinkling altogether 34 which he perceives would be pretty drastic for just a few homes 35 whose problems probably aren't caused by the extra demand on the 36 system. 37 The Public Works Director said because his men had been unable to 38 get into the two homes with low pressure problems, he was going to 39 write to those homeowners to see if they wanted his department to 40 make an internal inspection to try to find what was causing their low 41 pressure.
