OK - thanks! I do appreciate your advice.

Understood. That will take a little time. In the meantime, do you think that the pressure drop across the shutoff valve could also have a small effect. If I could eliminate at least that restriction, would it make any difference? I know, I'm reaching. The grandkids are boarding the plane!

Thanks ajw. An easy short term answer would be to change the current 3/4" valve to a full port valve. Would that make any significant difference?

Hi all, Thanks for all of the advice. Got the manometer. I've got 8" WC on the inlet (statically) but it drops to zero when the gas valve opens. I now get the flame to light momentarily but it doesn't stay lit. Based on what y'all have said, it seems that I am starved for gas. Do I read...

Ordered. Thanks for the reference!

Hi Jeff. I meant the regulator on the pool heater, not the main regulator. Do you see issues with that? I know it is not my first choice but may be a stop-gap.

No manometers at HD. So, if it is being starved for gas, it seems that my only option short term is to crank the gas valve regulator open.

You're right. It is a 250 CFM meter. We did have a 400 BTU unit here before that seemed to run ok. This one has been there for about 3 years and seemed to work until this year. In the spring, we seemed to have the problem of it starting up, lighting, and then going out. Through many...

In the Houston area. I wondered about gas supply as well.

Hi all. I know there have been threads on Mastertemp issues, particularly around the igniter and the magical 1 micro amp reading. I haven't been able to find a meter to read down to 1 micro amp so I haven't been able to do that. But, here's what is happening now. The fan comes on, the gas...

Hi all, I've got an old cleaner - it says it is a Leslie's Legacy - which I think is a Polaris origin. There is no other info on it. It has a dedicated pump and outlet. The hoses and tail are shot and, rather than rebuilding, I guess I'll have to break out the checkbook and get a new one...

No that's not it. This is spread evenly across the water line on the rocks themselves. For the waterfall, it is a six inch band or so, again right where the water flows.

Thanks, Bruce. No, it is not a salt water pool (excluding all that stuff above the water line!).

Hi all, I've been using the BBB system for almost a year with fantastic results. Thanks for all the help and support in the forums. I've been going through the scale forums as I have a scale issue. My pool surround is some type of canyon stone, which has a ring of scale around the top. I've...

Thanks all. This is a great help. I'm an engineer by education and am stubborn to boot. Once I know why I should do something, I'm a convert. So, understanding why a lower pH is better, and helps reduce chlorine usage and calcium hardness, I'm on it. I live in Houston and keep the pool...

Thanks Polyvue and dman. Good suggestion on the overnight test. Here's my before and after. After adding bleach and acid yesterday: FC: 6.0 ppm pH: 7.5 This morning: FC: 5.5 ppm pH: 7.6 (as much as you can estimate that color difference!) For some reason, my pool likes to be at 7.8 - 8.0...

The great news is that I don't have a problem (that I know of)! I started the BBB method in June with a good shock to about 22 ppm. It fixed everything. We've stayed in control for the whole summer doing nothing more than adding bleach and acid. My question - is there a point where I should...

Thanks all for the welcome. I guess the vacation thing is valid, so I guess I'll have to keep them. My CYA is still at 80 so I'm very reluctant to add any more - and that's really been the biggest source of my problem. Right after Hurricane Ike, it had risen to 400. No wonder I couldn't get...

Hi all, This is a great site. I've done things out of order - tapping into your knowledge and the signing up! I was so tired of a cloudy pool, numerous trips to the pool store with samples, and numerous trips home with more expensive chemicals and the direction to shock the pool - again. I...
