I live in the Wylie area. For the last month, we have been waiting to plaster. We’ve drilled holes, nothing has worked. I received this email from my pool builder: “We have you in line to use the diaphragm - Just to let you know it might be a a week to 10 days unfortunately. I will keep you posted when I know more next week”

Does anyone know what a diaphragm is? What’s the process? What it does? I’ve tried researching but haven’t been able to find any information online.

82,

The Diaphragm is a type of pump that can suck water out of the ground.. A sump pump can only suck water when the water covers the pump.. a diaphragm pump does not need to be underwater to work..

I had the same basic problem with ground water.. In my case they had to remove about 50 feet of decking and install a 6' deep' 18" wide and 50' long trench filled with gravel with a french drain at the bottom. The french drain carries the water to a 8' deep well that has a sump pump at the bottom. My pool is now about 5 years old and that pump has run (on and off) 24/7 and 365. It even runs on the hottest day in the summer.. Too bad it was not oil... :mrgreen:

Thanks,

Jim R.

No sure it is faster, but it works off of a moving diaphragm and not an impeller like a sump.. It can suck up a mixture of water and air, while you can not let a sump pump run dry..

The tried many different things on my pool and never succeded until I told them to install the french drains. Delayed my build 4 or 5 months.
