Just pump some shower scrubbers through the pipes periodically. Have a tee and a valve on the bull of the tee to pull it out when it gets to the pump. We do this on a much different scale in the natural gas industry. It's called "pigging a pipe".
If you got real intersted, you could pipe in a "pig" catcher (shower scrubber catcher).
(The wire bristled cleaning missile (pig) we send through the pipe squeels like a pig when it goes through at almost super sonic speeds)
Congrats so far, nice house and build.
Thanks Delmo. Ill deal with the potentially clogged PVC in about 20 years - or let the next homeowner deal with it.

Beautiful build; house and tank. I wish you the best.
thank you Dan. appreciate the well wishes.
Daniel. :wildone:
amazing build!
Thank you!
To all- amazing progress going on at the house. The hallway wainscot is almost complete- probably by the end of tomorrow if not sooner. Flooring is going in next and other than some minor clean up and touch up stuff, we are heading close to the home stretch. Stucco is all complete outside and the roof tiles will be done by next Wednesday.
They still have some lighting to put in, some carpets in a couple of the rooms, appliances and fixtures in the bathrooms, but really I figure by the end of july all the hard work will be complete and that will give them the month of August to do any final adjustments.
Thanks all for allowing me to share our home. Im really waiting for a bit of clean up to be done before I do another major photo update. Probably over the weekend will be a good time to reshow the house.
