Hi Tkd,
Therps are like plumbers,some are good,conscientious,and know what they're doing.And some are poor,hardly know one end of a
pipe from the other,and assure you it will be OK only to leak again.
There ARE good Th.though,you just have to find them--do NOT accept poor quality,if you seen that in a dress you'd take it back,same principle with Thp. You deserve a GOOD ONE,one way you can gauge is,ARE YOU TREATED WITH THE UTMOST RESPECT?
If not,shop elsewhere.
Good Luck,
BLUEDOVE.
