I have a pool where the pressure rises about 20 psi when the return lines are on the spa. On most pools the pressure rises about 10 psi when the returns are on the spa. The other abnormality on this pool is that the jets in the spa will go in and out, there will be pressure on a jet and then...

I would like to extend the amount of time between cartridge filter cleanings on my route. Many filters are undersized and for many customers its not an option to put in a properly sized filter. My two main ideas are enzymes and cyclone pre filters (1/4 the cost of upgrading filter). Keep in...

New Pool 13k gallons. IC 40. I lowered the alkalinity to 70 before adding boric acid. I added the amount of boric acid that the pool calculator said was needed. I checked the alkalinity a few days later and it was up to 130. Ph was at 8.0. Does this make sense at all? What would have caused...

I am installing my pump for my new pool. Local code requires 4x the diameter pipe of straight run into the suction side of the pump. My question is whether a praher union would count as straight run. My pad is small and it would be nice if the space the union takes would go towards my straight run

I have a blower for a spa that is not turning on. The previous owners had an air switch connected to the blower that they had cut out. Is it possible the reason the blower wont turn on is because the air switch was off before it was cut out? If so is how can i either bypass the air switch, or...

I have a pool that has 1 in piping going to the skimmer and the dedicated suction line. This results in not being able to get good enough flow to run the skimmer and the vacuum effectively at the same time. The timer box has a second intermatic timer available from an old booster pump. Is...

This heater is turning on and working fine for about 15 minutes and then it clicks off and says service heater. Does anybody have any idea why this would happen? I figure that if it is working for 15 minutes that it is not something to do with the pressure switch, but correct me if i am wrong...

Got a pool that sat for well over a year with nothing but disgusting water in it. Eventually most of the water evaporated and left a huge black stain in the deep end of the pool, as well as dark yellow stains all through the rest of the surface about halfway up the walls. Muriatic acid...

Has anybody tried this product to add borates? They suggest adding 5lbs per 6000 gallons. I dont know but that doesn't sound like it would be enough to get to 50ppm.

I have a blower motor that is turning on and it sounds good, but it is not forcing any air into the spa. The blower motor is positioned below the water level of the pool by about a foot. A couple feet below the blower is a check valve. Is it possible that the back pressure of the water...
