Versand könne etwas schneller sein (aber das lag vermutlich am Jahreswechsel und Feiertag) sonst alles top!

A little pricy for what it is, but it gets the job done. The check ball in my old valve had swollen with age and the pump had to work long and hard to push the condensate past the swollen ball. I thought about saving a few dollars by just removing the ball from the old valve and then installing an inline check valve in the discharge tube but, as they say, "time is money" and additionally, an inline check valve would also mean 2 more connections (potential leaks) in the discharge tube. This was definitely the better way to go.

The installation man suggested a new pump which cost is from $150 to 350. We just replaced the valve that fits several pumps and can use it without purchasing a new furnace water pump. I don’t understand, why a contractor would suggest a new pump instead of ordering the valve, which he could do himself and charge a double cost, which would be acceptable. The cost of the valve was only $10 and it was replaced with no problem !!!!!
