One last question before I install that new bladder tank.
What would be the best to use on the threads between the pvc and the galvonized pipe. My old system had galv. from the water supply line up to the copper that runs thru the house. I am switching it over to plastic from the bladder tank to the "T" that connects the water supply (from the well) and then up to the copper house lines.
What would be best, teflon tape or pipe dope between the plastic and galv. I was thinking the tape but was told by someone he would use the pipe thread sealant?
Is it either or or is one better than the other?
Thanks TOM

There is a teflon sealant that I like on the plastic threads. I do not like the regular iron pipe dope on plastic.
I have used miles (well maybe yards) of the tape and it works good also. BUT I like the ease of the teflon sealant and it just seems to work better.

Not off the top of my head. I just threw out 3-4 part used bottles of it a couple of months ago too. It does get stale and requires alcohol to re thin.
It easier and less concern just to get a new bottle when I need it.
The auto parts stores carry it also. Ask for a liquid teflon pipe sealant.

A plumber clued me in to Megaloc - I believe that is a liquid teflon sealant. It is great stuff.

Broken - I looked Megaloc up - it is manufactured by Hercules Chemical Company. We got our can about 8 years ago in someplace like True Value Hardware store. It should be sold in any good hardware store. It appears it does not contain Teflon but will fix any leak.

Since the middle of Dec. when I installed the new tank with all PLASTIC and no cast, I have not had a problem. (Shhh I did not want to say anything till a few months, you know that Murphys law)I use just regular old harveys sealant for the threads (all I could find in the store and since I had it already just used what I had). NO LEAKS and there is a heck of alot of water I can run between the pump turning on now.
Only thing I am not sure of is the pressure still wont stay up at 60psi. It shuts off at 60 and quickly drops to around 54 and stays there. Dont know if the older pipes in the other house has a light pressure leak and at 54 it is not large enough to push out anymore or what. But I am real happy with it at 54 down to 38 before it kicks. I used to have a 30/50 before I installed the larger 40/60.
I turned the setting on the new one to click off at 56 now and it turns on at 35. Thats more than enough pressure and dont want to create more of a headache than I need if too much pressure is on the older pipes?
Hey thanks for all the suggestions. In the end I followed my gut but you guys just reasured me and gave me the confidence that I was not messing up!
Thank you
TOM

Some water pumps have spring loaded check valves, maybe you have a tired spring in the check valve on one of your pumps.
