Performed KCM and draining and flushing of the tankless water heater. Flushed the tankless with distilled white vinegar for 45 minutes. Cleaned inlet filter. Bled lines of air and vinegar residual after flushing. Water pressure at house is at 80 psi. Water temp is 120. Recommended new washing machine hoses and to replace four old full turn style shutoff valves. Crawlspace appears in good condition, recommended getting some traps to prevent rodents from entering the crawlspace. No leaks or abnormal fittings observed in the crawlspace drain or water piping. Bathrooms appear in good condition, found one small leak at the bathroom sink but was able to hand tighten the nut and stop the leak. Could not enter second half of the crawlspace due to the crawlspace door was unable to be opened because siding had been installed around it. The customer did not renew there membership but would like to think about it. There membership expires in one month. Thank you for choosing CPI plumbing and Heati
