Ebibuuzo ebitera okubuuzibwa¶

Kiki ekisinga okuba eky’obukuumi ku bbugumu ly’ekyuma ekibugumya amazzi mu maka singa tuba n’abaana abato oba ab’omu maka abakadde?¶

Ekitongole kya U.S. Consumer Product Safety Commission (CPSC), American Burn Association, n’ekitongole ky’amasannyalaze bawa amagezi okuteeka ebyuma ebibugumya amazzi mu maka ku diguli 49 Celsius (diguli 120 Fahrenheit), ekikwatagana n’akabonero akalaga nti “Low-Medium,” “Warm-Hot,” oba akabonero akalaga enjuyi essatu ku dial ezisinga ez’okubugumya amazzi ga ggaasi. Bw’oba obeera n’abaana abawere, abaana abato abali wansi w’emyaka 5, abantu abakulu abasukka mu myaka 65, oba omuntu yenna alina obulwadde bwa sukaali/obusimu oba okukendeera kw’okutambula, teekako vvaalu z’okutabula ebbugumu mu kifo ky’okukozesa ASSE 1070 oba teekawo ekkomo ku kkomo ly’okuzimbulukuka kw’ensuwa olwo ebbugumu ly’amazzi erisinga obunene erifuluma mu bbaafu n’ebifulukwa by’okunaabira lireme kusukka diguli 43 ku 46 Celsius (110 okutuuka ku Diguli 115 eza Fahrenheit).

Lwaki ttaapu yange ey’amazzi agookya yasesema mangu empewo n’omukka bwe nnagikoleeza enkya ya leero?¶

Ttaapu y’amazzi agookya bw’efuuwa, ekuba, n’okufuuwa ensawo ez’amaanyi ez’omukka n’amazzi agabuguma ekintu ekisooka ku makya oluvannyuma lw’okutuula ekiro nga tekikozesebwa, ekyuma kyo ekibugumya amazzi kyalemererwa okuggala ekiro ne kibugumya amazzi agali munda waggulu wa ttanka nga gasukka diguli 100 (diguli 212 eza Fahrenheit). Nga ttaapu ziggaddwa, kilopascals 350 ku 550 (50 ku 80 PSI) eza puleesa y’amazzi ga munisipaali munda mu payipu zo eza ppipa zakuuma amazzi ago agabuguma ennyo obutafumbira mu ggaasi (kubanga amazzi agali wansi wa 60 PSI gafumba ku 153°C / 307°F mu kifo kya 100°C / 212°F); mu kaseera ke waggulawo ttaapu n’osuula puleesa okutuuka mu bbanga (0 PSI), amazzi agaali gabuguma ennyo gaayaka mu kaseera ako ne gafuuka omukka munda ddala mu kifo ekifulumya ttaapu. Ggalawo ekimenya ekyuma ekibugumya amazzi oba vvaalu ya ggaasi amangu ddala.

Singa ekyuma kyange ekibugumya amazzi kibuguma nnyo ate nga ne vvaalu y’ekikomo eya TPR eri ku ludda etonnya amazzi agookya, nsobola okusiba payipu okuyimiriza okukulukuta?¶

TOSIKA, tosiba, ggyawo oba okusikula vvaalu eggalawo hoosi y’olusuku ku payipu efulumya amazzi mu vvaalu ekendeeza ku bbugumu ne puleesa (TPR) ku bbugumu ly’amazzi oba bboyiyira. Valiva ya TPR ye mechanical fail-safe yokka etangira ekyuma ekibugumya amazzi ekisukkiridde okukutuka mu kubwatuka kw’omukka okw’akatyabaga (BLEVE) okuyinza okusimbula ttanka y’ekyuma eya ggaloni 50 butereevu okuyita mu myaliiro ebiri egy’ennyumba; singa vvaalu ya TPR efulumya amazzi agookya oba omukka, eba etaasa nnyo obulamu bwo kubanga oba thermostat y’ekyuma ekibugumya amazzi eremereddwa mu kudduka oba ttanka yo ey’okugaziya ebbugumu ejjude amazzi.

Npima ntya ebbugumu ly'amazzi ga ttaapu gange amatuufu awaka singa dial yange eya water heater egamba nti "Warm / Hot / A / B / C" yokka?¶

Olw'okuba ennamba ezikyukakyuka ku bbugumu ly'amazzi erya ggaasi ("Low / Hot / A / B / C / Very Hot") zimanyiddwa nnyo nga tezituufu era zisobola okwawukana diguli 10 Celsius (diguli 18 Fahrenheit) okuva ku bbugumu ly'amazzi lyennyini, engeri yokka entuufu ey'okuteekawo ekyuma kyo ekibugumya amazzi eri ku ttaapu y'omu ffumbiro. Ggyako ttaapu y’amazzi agookya mu ffumbiro ng’ekulukuta mu bujjuvu okumala eddakiika 3 okutuusa ng’ebbugumu litebenkedde, kwata ekipima ebbugumu ly’ennyama y’omu ffumbiro oba ekipima ebbugumu ekya ssweeta ekya digito ekisomebwa amangu mu mugga ogukulukuta (oba munda mu mug nga gujjula buli kiseera omugga), era otereeze dial yo ey’amazzi agookya n’ennyindo emu buli ssaawa 3 okutuusa ng’ekipima ebbugumu kisoma diguli 49 ezitakyukakyuka (diguli 120).
